*UPDATE: *Type definition updated. 

*Introduction:-* Your Business Workplace on Web!!!. This weblog will explain you how to trigger the Workflow and Execute (Decision making) the Workitem from Web using BSP Application. Also you can play around with Workitem with various options like Reserve/Re-submit/Reset etc… *Scenario:-* I took simple scenario to let everyone understand. Applying leave request from web, Applicant will get the initial notification and Manager will get an Workitem to “Approve”/”Reject” the Leave request. As soon as the decision is taken from Manager, applicant will be informed regarding the status. Note: This blog is not intended to explain Workflow concepts. *Highlights: – *Let’s look at the roadmap before we start.

  1. A Quick view of Workflow, which I used.
  2. Development of Leave request BSP application – To apply a leave. Also this will send the initial notification to applicant and submit the request for approval in the form of workitem in Manager’s (as set in Workflow) Inbox.
  3. Result-1: – Notification in applicant inbox and Workitem in Manager’s Inbox.
  4. Development of Web Business Workplace where your Manager can look at all the Workitems & carry out the necessary actions (decision making).
  5. Configuration involved to link your Workflow Task & BSP Application to make it more dynamic.
  6. Result-2: – View all the responsible Workitems and select one of the item to carry out the decision making.

Before we start our steps, lets look at the Workflow, which we are going to use.

    Let’s start with simple task…

  3. *Development of Leave request application *Create the BSP Application called *YMY_LEAVE*.*Page attribute:*0.1. image 0.2. *OnInputProcessing:* * event handler for checking and processing user input and * for defining navigation * Container Set Element DEFINE SWC_SET_ELEMENT. CALL FUNCTION ‘SWC_ELEMENT_SET’ EXPORTING ELEMENT = &2 FIELD = &3 TABLES CONTAINER = &1 EXCEPTIONS OTHERS = 1. END-OF-DEFINITION. DATA : IT_CONTAINER TYPE TABLE OF SWCONT, WF_ID TYPE SWWWIHEAD-WI_ID. DATA: FIELDS TYPE TIHTTPNVP, DB_START TYPE SYDATUM, DB_END TYPE SYDATUM, WA_FIELDS LIKE LINE OF FIELDS. DATA EVENT TYPE REF TO CL_HTMLB_EVENT. EVENT ?= CL_HTMLB_MANAGER=>GET_EVENT_EX( REQUEST ). IF NOT EVENT IS INITIAL. IF EVENT->SERVER_EVENT EQ ‘myLeave’. CALL METHOD REQUEST->GET_FORM_FIELDS CHANGING FIELDS = FIELDS. READ TABLE FIELDS INTO WA_FIELDS WITH KEY NAME = ‘start_date’. IF SY-SUBRC EQ 0. START_DATE = WA_FIELDS-VALUE. CALL FUNCTION ‘CONVERT_DATE_TO_INTERNAL’ EXPORTING DATE_EXTERNAL = START_DATE IMPORTING DATE_INTERNAL = DB_START EXCEPTIONS DATE_EXTERNAL_IS_INVALID = 1 OTHERS = 2. ENDIF. READ TABLE FIELDS INTO WA_FIELDS WITH KEY NAME = ‘end_date’. IF SY-SUBRC EQ 0. END_DATE = WA_FIELDS-VALUE. CALL FUNCTION ‘CONVERT_DATE_TO_INTERNAL’ EXPORTING DATE_EXTERNAL = END_DATE IMPORTING DATE_INTERNAL = DB_END EXCEPTIONS DATE_EXTERNAL_IS_INVALID = 1 OTHERS = 2. ENDIF. READ TABLE FIELDS INTO WA_FIELDS WITH KEY NAME = ‘reason’. IF SY-SUBRC EQ 0. REASON = WA_FIELDS-VALUE. ENDIF. * Set the data into Workflow container SWC_SET_ELEMENT IT_CONTAINER ‘start_date’ DB_START. SWC_SET_ELEMENT IT_CONTAINER ‘end_date’ DB_END. SWC_SET_ELEMENT IT_CONTAINER ‘reason’ REASON. * Start the Workflow CALL FUNCTION ‘EWW_WORKFLOW_START’ EXPORTING X_TASK = ‘WS90200031’ IMPORTING Y_WORKFLOW_ID = WF_ID TABLES X_CONTAINER = IT_CONTAINER EXCEPTIONS INVALID_TASK = 1 NO_ACTIVE_PLVAR = 2 START_FAILED = 3 GENERAL_ERROR = 4 OTHERS = 5. IF SY-SUBRC = 0. COMMIT WORK. NAVIGATION->GOTO_PAGE( ‘result.htm’ ). ELSE. V_MESSAGE = ‘Your Leave Request is not posted into System, Try again later…’. ENDIF. ENDIF. ENDIF. 0.1. Create the *result.htm* page to display the results with following Layout.*OnInputProcessing:-* DATA EVENT TYPE REF TO CL_HTMLB_EVENT.EVENT ?= CL_HTMLB_MANAGER=>GET_EVENT_EX( REQUEST ).IF NOT EVENT IS INITIAL. IF EVENT->SERVER_EVENT EQ ‘back’. NAVIGATION->GOTO_PAGE( ‘Apply_Leave.htm’ ). ENDIF.ENDIF. 0.1. 0.2. Let’s look at the outcome of the Step-1. 0.1. Execute the BSP Application YMY_LEAVE and enter the data as follows: 0.2. image 0.3. Click on Submit button: 0.4. image 0.5. Let me look at my Business workplace (Tcode: SBWP), I must have received a notification mail in my Inbox. 0.6. image 0.7. Let me login into my approver’s Inbox; must have got the workitem as follows: 0.8. image 0.9. Select the workitem & Click on execute button to look at the workitem details. 0.10. image 0.11. Now the challenging part is how we are going to achieve Decision steps of workflow on web. I would like to make this process *dynamically* so that it will work for any workitems, not only for Leave request workflow. 0.1. 0.2. *Development of web workplace* 0.1. Develop a BSP Application called YWORKPLACE where you can see & execute all the workitems. 0.2. 0.1. Create a page called *main.htm* *Note:* This page will show all the workitems from Inbox and Re-submission folder with options to Execute/Reserve/Re-submit/Reset etc. 0.1.

Let’s work on Decision making page. This page has *Dynamic* capability to make decision making for any workitem, just you need to pass the workitem as parameter to it. You can create separate BSP Application or else you can create another page in YWORKPLACE Application itself. Name the Page as *”decision.htm”. *
  4. *Layout**Page Attribute:*0.1. image 0.2. *OnInitialization* 0.1. CALL FUNCTION ‘SAP_WAPI_DECISION_READ’ EXPORTING WORKITEM_ID = WORKITEM_ID IMPORTING DECISION_TITLE = DECISION_TITLE TABLES ALTERNATIVES = ALTERNATIVES. CALL FUNCTION ‘SAP_WAPI_WORKITEM_DESCRIPTION’ EXPORTING WORKITEM_ID = WORKITEM_ID TABLES TEXT_LINES = TEXT_LINES HTML_TEXT_LINES = HTML_TEXT_LINES. 0.2. *OnInputProcessing:* DATA: EVENT TYPE REF TO CL_HTMLB_EVENT. DATA: RETURN_CODE LIKE SY-SUBRC, NEW_STATUS TYPE SWW_WISTAT. DATA: WA_MESSAGE_LINES LIKE LINE OF MESSAGE_LINES. EVENT = CL_HTMLB_MANAGER=>GET_EVENT( RUNTIME->SERVER->REQUEST ). IF EVENT->NAME = ‘button’ AND EVENT->EVENT_TYPE = ‘click’. DECISION_CODE = EVENT->SERVER_EVENT. CALL FUNCTION ‘SAP_WAPI_DECISION_COMPLETE’ EXPORTING WORKITEM_ID = WORKITEM_ID DECISION_KEY = DECISION_CODE IMPORTING RETURN_CODE = RETURN_CODE NEW_STATUS = NEW_STATUS TABLES MESSAGE_LINES = MESSAGE_LINES. ENDIF. 0.1. Last step is, linking our workflow Task (Decision making Task) & BSP Application (Basically Page/controller which used for decision making) using *Customization*. Follow the steps: 0.1. Goto Tcode SWFVISU & Click on “New Entries” 0.2. image 0.3. Enter the Task number which is responcisble for desicion making & Visualization Type as “BSP Standard” 0.4. image 0.5. Select the entered row & double click on Visualization Parameter under “Task Visualization” 0.6. image 0.7. Enter the following Parameters. In my case, I created another page in same BSP Application. You can also create the another BSP Application for decision making process. 0.8. image 0.9. Save the entries. It might as you customizing request to save. 0.10. 0.1. 0.2. Now we all set to see output 0.1. Let me Execute BSP Application “YWORKPLACE” Page “main.htm” using “Approvers” user ID. Page will display all the workitems as shown below: 0.2. image 0.3. Once you select the workitem, relevant buttons will be enabled to process the workitems 0.4. image 0.5. You can Execute/Reserve/Re-submit/Reset etc. Just for demo, let me click on Reserve button 0.6. image 0.7. Look at the workitem in GUI, status should changed into “Reserve” as shown below: 0.8. image 0.9. Key thing here is, execution of workitem. Let’s click on “Execute”. *Dynamic decision-making *screen will pop-up as per our customization. 0.10. image 0.11. Click on “Approve”: 0.12. image 0.13. The workitem must have vanished since it’s approved and applicant will be informed via mail as shown below: 0.14. image

      Thanks Raja D, Nice to know you were thinking similar to this one..

      I invested solid amount of time to find things on place to integrate  Workflow with BSP, so thought it would be great help for the community…

      Regards,
      Raja T

    First of all i would take a moment to thank u for a very helpful BLOG.
    I am fairly new to BSP’s and Workflow.
    I tried the blog on CRM 5.0, I made a workflow and was able to execute the it till the point where(Appliocation is executed and get a notification in MAilbox is achieved)

    Problems faced:
    1.)I was not able to define the some of the    variables as they dont exist on the CRM server like TVC , UWL and etc. Any workaround for this.

    2.)While customizing in the TCODE SWFVISU
       i Was not able to define OPEN_WINDOW (Visualization parameter) EQ ‘X’.

      Thanks for your comments..
      [i]1.)I was not able to define the some of the variables as they dont exist on the CRM server like TVC , UWL and etc. Any workaround for this.[/i]
      –> I developed this scenario in ECC6.0. I’m not sure whether these variables are  available in CRM system. I dont have access to the system now. I will post you fields of TVL, UWL structure..

      [i]2.)While customizing in the TCODE SWFVISU
      i Was not able to define OPEN_WINDOW (Visualization parameter) EQ ‘X’.[/i]

      –> YOu need customizing to make it more dynamically. YOu can hard the BSP Application  & parameter without customizing. If you need more detail please open a forum thread under BSP area.

    Hello Raja,

    Thanks for the e.g.

    Is there any way for the user to trigger an Approve/Reject work item and send the outcome to the server workflow as an event without the user logging in.

    Like encoding the User E-mail or Event name as part of the link in the Outlook E-mail….

    Any Ideas…..

    Thanks
    Arun

    Hi Raja,

    Thanks for a nice blog…

    My question is if we integrate the workflow with the UWL of portal using webflow connector…

    On execution of the above workitem can we see the BSP or anything else(ITS etc..)?

    Please clarify..

    Thanks..
    Ravi

    UWL_LINE
    TVC     
    UWL
