The Part I of Workflows Introduction gives the basic details about the workflow usage as a tool and the features involved. In Part II, the details about the workflow builder will be covered. In the subsequent parts, more details about the runtime analysis tools of workflows will be discussed.
What are SAP Business Workflows:
Using SAP Business workflows, one can define the business processes that are not yet mapped into SAP system. Workflows are suitable for the situations where the given task is executed repeatedly or when the large number of people is involved in the completion of that work. Workflows can be used in conjunction with the existing business scenarios e.g. during the standard functionality errors or exceptions occurs then workflow can be triggered on these actions.
There are lots of standard workflows available from SAP for different areas like Sales & Distribution (SD), Travel Management (TV), Treasury (TR), General Logistics (LO), and Personnel Management (PA) etc.
Why Workflows:
Following are the scenarios, which occur on daily basis in each organization –
  • Finding out what work needs to be done
  • Planning of work that needs to be done amongst the group of people
  • The identification of roles & responsibilities on who will do what, when & in how much time
  • Working in coordination with others
  • Informing next person about his work to be done, when the earlier one has finished his own
  • Duplication of work that has been already done because of communication gap,inefficient knowledge transfer & the incomplete documentation in the central repository
  • Identification of delay in the completion of the work
  • Preparing status on this delay
  • Workflows help to optimize each of the above scenarios. In workflows the processes are linked to each other and flow one after the other. At each step, a right person (Agent) will take care of the process. If the step doesn’t need any interaction then the process flows automatically.
    Here deadlines can be set for the activities depending on the fair time that step needs to complete. Once this deadline is reached and the process is not performed by the concern then the administrator (manager) gets the notification mail. Here as the right people can be kept in loop in this automated process so a disciplined work atmosphere is automatically planned in the organization.
    Due to this automated system, the process becomes transparent to all the users and the risk of manual errors is also reduced. Again the time required to complete any work manually is simply reduced in this automated system. So this adds to the quicker completion of targets and hence leads to the financial growth of the organization.
Features of Workflows:
  • New business processes can be easily defined with the workflows.
  • Workflow uses the existing transactions and functions without changing them.
  • Workflow uses the Organization structure. This helps in the term of changes to organization structure, which will be immediately in effect in the execution of workflows.
  • Lots of tools are available in the workflow like tools for definition, analysis and monitoring of work processes.
  • Workflow template (transaction: PFTC) can also be created for the workflow definitions.
  • Workflow Builder is a very effective tool available for creation, change and display of workflow definition.
  • Agents can be easily maintained in the workflows. They receive the work item in their SAP Business Workplace, which they will process.
  • Deadline monitoring can be easily used against the tasks for the defined agents.
  • Using Business Object Editor (transaction: SWO1), we use the business objects in workflows. These business objects help to use the SAP standard functionality in workflows.
  • ABAP Classes can also be used in workflows along with the business objects.
  • Business Workflow explorer gives the overview of all the tasks.
  • Workflow can also be used on Internet. This is especially useful for the managers, who might not be directly accessing the SAP transactions. So the approval forms generated via workflows can be sent on internet. This is even useful for the people who mainly preparing SAP data and not knowing much about the SAP transactions. They can be given a simple web form for entering data & on submitting data of this web form workflow can be started.
  • Several workflow wizards are also available for supporting the workflow definition
  • Version management is available for workflows. Only one version can be active at one time, which is referred while execution.
  • Lots of administrative tools are available for control and analysis of workflows.
  • Lots of diagnostic tools are also available in workflows.
Prerequisites of using Workflows:
  • System Requirement: R/3 Release 3.0 & above
  • Mail servers involved should be SMTP Compliant if the workflow involves email notifications.
  • As the workflow may execute lots of background jobs so it may require lots of system resources. Hence the hardware should be enough to fulfill all these requirements along with the normal functionality of the server without affecting the speed.
  • Customization Settings:
    • Following are the customizing settings needed to use workflows-
      • With the System Supervisor ID, go to transaction SWU3(Automatic Workflow Customizing)
      • Click on the button Perform Automatic Workflow Customizing (F9) from the application toolbar for performing automatic customization of the workflow.
      • Once this is done, all the check marks below should turn green
      • Along with so many settings available in the workflow customizing, system automatically creates a batch user WF-BATCH. This user has SAP-ALL authorizations to execute the workflow.
      • Now, go to table T78NR from Customizing SPRO transaction.
      • Click on Create button from the application toolbar to create a new prefix range.
      • Give the Prefix Number as 900 for custom development & click on Save button.
      • The newly created prefix appears as activated in the table.
    • The user triggering the workflow should have his email ID maintained in the SU01 transaction.
    • SMTP Configuration:
      From SAP WAS 6.10, SAP directly supports SMTP (Simple Mail Transfer Protocol). This means that the emails can be exchanged directly between SAP system and any SMTP compliant mail server. From SAP WAS 6.20, faxes, pager & SMS can also be exchanged via SMTP.
      • Goto transaction SCOT.
      • Goto menu View -> Node
      • Goto SMTP node. Double click on the required node which is * in this case.
      • Click on the Maintain Node button.
      • Give the Mail Host & Mail Port for outgoing mails. Click on Set for Internet options to set.
      • Give the Address Area as * for the receipt addresses. Also set the Output formats for the SAP Documents as shown in the image below. In the specified format the output will be sent as attachment in the email.
        Confirm the settings.
      • Similarly Pager/Fax settings can be done. For Pager(SMS), the prerequisite is that in transaction SA14, the paging services should be defined. Once this is done, the here in the SCOT transaction, click on Set adjacent to Pager (SMS).
      • Mention as * in the Address area for the receipt number and Domain name in the Domain input.
      • Confirm the entries. The SMS will be of the format SMS=+ReciptNumber@Domain
Transactions Involved:
Lots of transactions are involved in the Workflow tool. Majority of them are for runtime analysis and diagnosis. The details of these transactions can be found from SAP Easy Access menu.

Following are the frequently used transactions –

  • Customization Settings:
    • SWU3 – Automatic Customizing Workflow.
    • SCOT – SAP to mail server Configuration
    • SU01 – User Maintenance
  • Workflow Design:
    • SE37 – Function Builder
    • SE38 – ABAP Editor
    • SWO1 – Business Object Builder
    • PFTC – Task Maintain
    • SWDD – Workflow Builder
  • Runtime Behavior/Analysis:
    • SBWP – Business Workplace
    • SWUD – Workflow Diagnosis
    • SWU_OBUF – Synchronize Runtime Buffer
    • SWPR – Workflow Restart After Error
Workflow Terminologies:
  • Workflow builder: Workflow builder is the business workflow tool for creating, editing and displaying the workflow definition.
    The Workflow Builder provides a graphical modeling view, which gives a direct overview of the processes of the different steps. Also there is a tree view to shows all steps of the workflow definition in a hierarchical view.
  • Workflow Container: The workflow container contains workflow-specific system elements as well as other container elements, which are defined explicitly.
    Container elements for which the import or export indicator is set form the interface of the workflow. This interface is valid for all versions of the workflow definition. Container elements for which no import or export indicators are set are local container elements of the workflow definition and are valid only in the versions of the workflow definition in which they were defined.
  • Workitem: Workitem is runtime representation of a task or a step in the workflow definition. There are various types of work item.
    The SAP System determines the recipient(s) of a work item i.e. Actual Agent from the intersection of responsible and possible agents. If this intersection is empty then no body will get this workitem for further processing.
  • Dialog Workitem: A work item (type W) which at runtime represents a workflow step or a task that requires dialog with the user. Typically, dialog work items are displayed in the Business Workplace. When a dialog work item that is based on a task is executed, the underlying object method is called. You can monitor deadlines for dialog work item execution.
  • Triggering Event: Triggering event is the one, whose occurrence triggers or starts the workflows or tasks.
    The event must be entered as a triggering event for the task or workflow that is to be started. The event linkage must be activated. The event must be defined as an object type component in the Business Object Builder. A task or workflow can have several triggering events. Information from the event creation context can be passed in the binding from the event container to the task container or workflow container.
  • Block: Block is an element of workflow definition. It contains the consistently arranged steps and operators. It has one start and one end. The consistency and robustness of a workflow definition is ensured because a block is always created when a new step is created, or an undefined step is changed. Similarly, when individual steps are deleted, cut, or inserted, the entire block in which the step is located is affected.
  • Step: A step is an entity, which can be inserted into the workflow builder. Whenever executed, step gives the predefined desired results.
    The step is always defined in block. There are different types of steps available in workflow builder to perform different kinds of operations. These steps are Activity, Web Activity, Send Mail, Form, User Decision, Document from Template, Condition, Multiple Condition, Event Creator, Wait, Container Operation, Process Control, Loop(Until), Fork, Undefined, Ad hoc Anchor, Local Workflow & Block.
  • Task: Task (Standard Task, Customer Task) is used to define the Activity step in workflow definition. Task can be executed independently also.
  • Task Container: Task container is a location for storing data from the task environment. The task container contains the information about the object reference to the object to be processed, the actual agent of workitem, necessary input parameters for the method. These parameters come from workflow container after the binding between workflow container and task container. It also stores the information available after the method processing.
    The task container contains some predefined workflow system elements. One can define more container elements in the task container. It is also known as a work item container at runtime.
  • Responsible Agent: Responsible Agent is a user assigned to a step in the step definition. Expressions, organizational objects, or rules can also be used to assign the responsible agents.
  • Possible Agent: Possible agent is a user who is authorized organizationally to start a task and execute the relevant work item.
  • Actual Agent: Actual Agent is the person who receives a work item for further processing. The agent can be directly assigned to step or agent determination can happen dynamically at run time either from rule or from the organization structure.
Workflow Binding Concept:

There is three level of two way Binding concept involved in workflows. Here binding is meant by the interaction between two consecutive levels using variables (Import/Export parameters). The first level of binding exists between the event triggering the workflow and the workflow’s container i.e. workflow gets the necessary inputs for processing. The second level of binding exists between this workflow container and the step (task) container. And the third level of binding exists between the step (task) container and the method inside this step (task).
Here the values in the variables are passed to workflows, which then flows to tasks & finally to corresponding methods as Import parameters. The outcome of these methods if needed can be passed back to task & then finally to workflow. The outcome of one task can also be passed to next tasks using this binding concept.

Workflow Builder in Brief:
  • Transaction for workflow builder is SWDD.
  • The workflow builder is divided into different areas like Information Area, Navigation Area, Step Types, Graphical Model, Results of Syntax check etc as shown below.
  • In the Information Area, the information about the workflows like workflow number, version and the status of the workflow are displayed.
  • In the navigation area, all the steps of workflow definition are displayed in sequence.
  • The Step Types appear in the Objects section of the workflow builder. This object section consists of following options in the dropdown, one which can be viewed in the workflow builder. e.g. in the current case, Step Types are displayed.
    • Step Types That Can Be Inserted
    • Workflow Container
    • My Workflows and Tasks
    • Document Templates
    • Workflow Wizards
    • Teamworking
    • Workflows of this Definition (Outcome)
    • Note It!
  • At the bottom of the workflow builder, the syntax check results are shown as either informatory, warning or error messages.
  • In the Graphical view, the actual definition of workflow is build by dragging the steps from the steps list or by right clicking the step directly on undefined one. The default steps in every workflow are Workflow Started, Undefined step and Workflow Completed.
  • Triggering Event for this workflow can entered in the workflow builder by menu Goto -> Basic Data. Here enter the relevant business object and the event name. Activate the link and binding.
  • Once the workflow is built here. It needs to be activated so that it can be used further.
  • Workflows can be locally tested at the Builder level also.
  • Following types of steps can be inserted into the workflow builder.
Step Name
image Activity Activity is used to execute the methods of Business Objects. At runtime it does the execution of a task or sub workflow
image Web activity The content of container elements is sent to a URL unchanged or in the form of a generated XML document. The step can wait for a reply. Communication with a process started by a Web activity is possible. A process started by an XML message can communicate with its caller.
image Send mail This is used to send mails to SAP, Internet mail addresses. The text entered in this step type is sent as an e-mail.
image Form The data in a container element that refers to a structure can be displayed, processed, or approved as a form.
image User decision The actual agent will be given choices to execute the workitem with different decisions. The process flow of the current workflow is controlled on the basis of a decision made by the current agent.
image Document from template A document is created from a document template.
image Condition One of two branches defined in the workflow definition is processed. The system makes the decision based on defined conditions. When doing this, this system takes account of information from the context of the workflow or the application objects processed.
image Multiple condition One of several branches defined in the workflow definition is processed. To do this, the system checks the value of a container element in the workflow container.
image Event creator An event is created.
image Wait for event The system waits for a specific event. The work item is only completed if the expected event occurs. The event can also be triggered by the occurrence of an XML document.
image Container operation Elementary arithmetic operations or value assignments are applied to individual elements of the workflow container. E.g. Setting up flag values for processing can be done here.
image Process control The functions Cancel work item or Set work item to obsolete are applied to other work items of the current workflow.
image Loop (UNTIL) A sequence of steps is processed repeatedly until the defined termination condition occurs.
image Loop (WHILE) A sequence of steps is processed repeatedly as long as the defined comparisons apply. The system leaves the loop when the basis of comparison does not agree with any of the comparison values.
image Fork The processing that follows takes place in a fork. One can define how many branches have to be executed for the fork to be successfully completed, or can define an end condition in the condition editor.
image Undefined step No function at runtime. Undefined steps always have an outcome.
image Ad hoc anchor In the definition, one can save workflows that can replace this step. At runtime, an authorized user can select one of the saved workflows. The ad-hoc anchor is then replaced by the steps of this workflow.
image Block Steps can be grouped together in workflow block.
image Local Workflow Local workflow in the caller workflow has the local container and has full access to the workflow container as well. The local workflow gets triggered by local events in the caller workflow.
How Workflow can be Started/Triggered:
Workflow can be triggered in following different ways –
  • Automatically By Triggering Events: Workflows can be triggered using events. Whenever this event occurs, workflow automatically gets triggered. For this, the event must be specified as the Triggering Event.
  • Automatically By using Workflow: Workflow can be triggered if it is specified as the step of another workflow.
  • Manually:
    • Workflows can be triggered manually in the standard environment where the necessary input data is given to workflow with triggering event.
    • Also workflows can be triggered in testing environment i.e. in development environment for testing purpose.
    • Workflow can be stared using Start Transaction. Start Transaction is the one whose execution allows all the import parameters of a workflow to be entered. After the start transaction has been executed, the SAP System starts the associated workflow with this data.
    • A user can start a workflow or task from a message issued by the system. A workflow or task must be assigned to the message. An appropriate function for this is available to the user in the message long text.

    Hi Sapna,

    That’s a really nice step-by-step view of how to start up using workflow.

    Sweet as a nut 🙂

    Hint: It will be easier to find this gem if you change the blog to include the “SAP Business Workflow” topic as an index and hopefully someone will add it to the Wiki workflow FAQ.

    Thanks for spending so much of your time to share this with others,

      your bolg was very nice. explanins much conceps about the workflows.

      i am already started working on workflow. i need to what is difference beween the workflows in version 4.7 and ECC5.0.
    in ECC 5.0 i am able to see more steps if you can please explain this in bit detail that will be help for me.

    one more thing is ecc6.0 i have seen some standard workflows that are triggered through document database. and even we are not able open these work items sap inbox these gets open only in EP UWL. if you can tell some thing about this also that will be use full.

    thanks in advance.

    Its pretty kool. It makes me familiarization with terminology and overall idea about workflow. Thanks a lot. Actually searched here to give points to your Blog but I didn’t find a option to Blogs.

    I am looking for Part II even if it is in rough copy stage can you mail me that to ‘

    Thanks for this blog.

    I have a question. Is the number range tranportable or must it be defined as a local object and redefined in each environnement manually ?

    Hi Sapna
    I am a begginer with Workflow, was going thru lots of stuff from Internet, but it was tough for me to understand.
    Your blog helped me a lot to understand the basics…

    Thank you ..
