Rohan is SAP certified Consultant and works in NTT DATA, He has work experience in SAP ABAP , Dynamic programming,

WebDynpro ABAP, POWL , Smart forms , Adobe forms and so on.

Main Steps Involve in creating POWL Feature.


  1. Create Feeder class
  2. Implement Feeder class method
  3. Define Application id, Type, Role and queries
  4. Integrate POWL with our WebDynpro application
  5. Test POWL

1. Create Feeder class.

  • For our example, we need to create tables for Data selection
  • Create a table name:  YEMPLOYEE, presented in Fig. 2.
  • Create Table entries for above table for references.
  • Create Table Type    : YTT_YEMPLOYEE ,presented in Fig.3

         

Fig. 2 Database table used for our example

         

          Fig. 3 Table type for database table YEMPLOYEE.


  • Now go to T.Code: SE24 and create a class with following interface, presented in Fig.4
  • Class Name          : YPOWL_CLASS.
  • Interface Name     : IF_POWL_FEEDER.

         

          Fig. 4 YPOWL_CLASS   is made and is using the interface IF_POWL_FEEDER.

  • Now create attribute for same class, presented in Fig.5
  • Attribute Name:

MT_RESULT                      Type      YTT_YEMPLOYEE.

MT_FIELDCAT                   Type      POWL_FIELDCAT_TTY

MT_SELCRITERIA             Type      POWL_SELCRIT_TTY

MT_CRITERIA_DEFAULT   Type      RSPARAMS_TT

                                 

          Fig. 5 Attribute for YPOWL_CLASS   is made.

  •   Implemented Feeder class has various methods as shown in Fig 6.

         

Fig.6 Interface Implemented methods.

NOTE:  It is not necessary to use all methods provided by interface from the start.

There are 2 mandatory methods and 6 optional ones.

GET_OBJECTS and GET_OBJECT_DEFINITION are two mandatory methods, rest are optional.

Method description:


               1.GET_ACTIONS: In this method, we can define the buttons and their action which can be handle in                    

                    Method HANDLE_ACTION. Method GET_ACTION properties defined in structure POWL_ACTDESCR_STY like text, tooltip, index etc.

             

               2.GET_ACTION_CONF: In this method, one can fire a confirmation dialog window  on the click of button, it will ask user whether to delete

                    the entries or not or similar.

              

               3.GET_SEL_CRITERIA: In these method selection criteria is defined for this particular feeder.  I.E Fields which appear in POWL selection screen.

      • Structure use: POWL_SELCRIT_STY

              

               4.GET_FIELD_CATALOG: This method describes the field catalog to be used for query results table and the UI properties of the particular fields.

      • Various properties can be set here: Column position, column header, column visible, column color etc.
      • Structure use: POWL_FIELDCAT_STY.

              

               5.GET_OBJECT_DEFINITION: This method is used to define the container (e.g. specify field types) where the selected data gets stored.

              

               6.GET_OBJECTS: This method is used to retrieve data from the backend system. Data retrieval can be done via simple select query or by

                    using a function module. Selected data is passed to E_RESULTS which is exporting parameter of this method

              

               7.GET_DETAIL_COMP:Enable the detail component feature.

              

               8.HANDLE_ACTION: In this, all the actions for the buttons are defined and also we can control enable/disable property of buttons here.

                    Control can be  transferred from class to portal via firing a event using :

      • E_portal_actions-fire_wdevent = abap_true.

2. Implement Feeder class method.

     NOTE: Please implement/Activate all method of feeder class, otherwise system will generate dump saying ‘Implementation is missing’.

3. Define Application id, Type ,Role and queries

  • After a feeder is developed, it needs to be made visible to the roles. Basically, this means we need to register the feeder under a specific APPLID, define a POWER List type and introduce it to the roles .

Step 1.Create an Application ID

    • Transaction code: FPB_MAINTAIN_HIER
    • Click on Change->Display button and then on New Entries button
    • Give  application id name:YEMPLOYEE_APPLID
    • Presses SAVE , it will ask for transport request. Give/Create transport request and save it.
    • Now u can see your entry (YEMPLOYEE_APPLID) in the list as shown below figure.

              

         

      Step 2.Create a POWL TYPE

    • Transaction code: POWL_TYPE
    • Click on New Entries button.
    • Give Type name : YEMPLOYEE_TYPE
    • Enter description and feeder class name as shown in below figure.
    • Presses SAVE, it will ask for transport request, add it to same request created for APPLID.
    • Now u can see your entry (YEMPLOYEE_TYPE) in the list.

    

      Step 3.Role assignment for POWL TYPE

Here we connect the APPLID with the POWL Type and make it visible to the role.


    • Transaction code: POWL_TYPER
    • Click on New Entries button and enter details as shown in figure.
    • NOTE:Role is Optional field and can be specified only if a role dependent mapping is required
    • Press SAVE, it will ask for transport request. Give/Create transport request and save it.

       Step 4.Query for POWL

Here we define default queries for power list. A query id is made which is connected to POWL type.

NOTE: you can define one or more queries.

    • Transaction code :POWL_QUERY
    • Click on New Entries button and enter details as shown in figure.

    • Press SAVE, and give transport request.
    • After this, we can create/see the query parameters and the query settings with the help of the corresponding buttons:
    • On clicking Query Parameter, you could see following screen, with field declare in feeder class.
    • On clicking Query setting, one can enable different feature like quick search for fields.

     Step 5.Map APPLID & QUERYID for POWL

Here if several queries are defined then sequence of tabs can be controlled via this transaction.

    • Transaction code :POWL_QUERYR
    • Click on New Entries button and enter details as shown in figure.
    • And tick the checkbox Activate.
    • Press SAVE, and give transport request

4. Integrate POWL with WD application

    • Transaction code :SE80
    • Create a Web Dynpro component YEMPLOYEE_POWL_WD and save it.
    • Define Component usage. POWL_UI_COMP,as shown in below figure.

    • Goto Views, Define POWL Component usage in properties tab of MAIN VIEW
    • Now, Define a view Container, Label and Text view inside the MAIN VIEW (POWL VIEW).
    • FOR CONTEXT NODE: Create node with single attribute EMP_NAME & bind it to TEXT_NAME
    • Now Go to Windows, in the properties tab of Windows, define the usage of POWL_UI_COMP component.

    • In WINDOWS, View container(VC_UI) embed the view Powl_Master of Powl_UI_Comp component as shown in fig.
    • Now click on Outbound Plug tab of window, give PLUG NAME & PARAMETER NAME.

PARAMETER NAME                 TYPE

APPLID                                    STRING

FORALLQ                                 POWL_XFLAG_TY

QNAME                                    POWL_QUERY_TY

QSELPARA                              STRING

REFRESHQ                              POWL_XFLAG_TY

SRVGROUP                              POWL_XFLAG_TY

    • Click SAVE and go to WINDOW tab and create navigation link for OUT.

    • Define the mapping of Outbound plug of windows with Default plug of view Powl_Master as shown:

    • In the methods Tab of Windows , write the code in Handle Default Event handler to fire the outbound plug to Powl_Master View :

METHOD HANDLEDEFAULT .
DATA: LV_INBOX_QUERY TYPE STRING,
LT_QUERY_PARAMS
TYPE RSPARAMS_TT,
LWA_PARAM
TYPE RSPARAMS.
DATA LV_QNAME TYPE POWL_QUERY_TY.

LV_QNAME = ‘YEMPLOYEE_QUERY1’.
CALL FUNCTION ‘POWL_ENCODE_SELPARA’
EXPORTING
I_SELPARA = LT_QUERY_PARAMS
I_ESCAPE =
‘\’
IMPORTING
E_SELPARA_STRING = LV_INBOX_QUERY.

WD_THIS->FIRE_OUT_PLG(
APPLID =   ‘YEMPLOYEE_APPLID’
QNAME =   LV_QNAME                 
FORALLQ =
‘X’                        
QSELPARA = LV_INBOX_QUERY          
REFRESHQ =
‘X’                        
*     REFRESHA = ‘X’                      
SRVGROUP =
‘X’ ).
ENDMETHOD.

5. Test POWL.

     Now create WD application and activate the whole program and run the application.

  • Initial Screen

          Here, You can

    • Define New query (Define New query)
    • Change Query (Change Search condition)
    • Personalize (Set Layout , Remove query , Set default query etc)
  • AFTER DEFINING NEW QUERY

    Thanks for the blog. I don’t know much about POWL, but it seems like a lot of effort to just get list of employees in WebDypro.

    Why wouldn’t you just use selection criteria and an ALV table in WebDynpro? Or was this example just for illustration purposes..?

    thanks

      Paul the personalization of queries based on role and user is the main feature which the POWL provide you.

      You can different set of BO’s or Objects at a same time using different queries.

    Great source of information. Thank you. As Paul mentioned could you please tell us the difference between having POWL and having an ALV with selection criteria to make different queries.

    Hi Paul / Sudhanshu,

    The Above article illustrates the steps on how to implement POWL in WD App. and List of employee output is provided for illustration purpose.

    There is already a generic work list tool offered in Enterprise Portal, called the Universal Work list (UWL), in this special need for user-definable work lists is not satisfied.

    This is because the UWL has just an opposite paradigm: the user is shown those objects he is obliged to process or to notice. E.g.: Selection criteria with ALV as output.

    The creation of a custom query that delivers a list of objects for  the respective user is merely

    Interested in or he has to select on its own for his daily work which is therefore not in scope of the UWL.

    This is where the Personal Object Work List (POWL) comes in: It is aimed at providing the user with a portal-based interface that he can use to define (and optionally store) queries in a similar way as he is used to do from R/3 selection screen variants. Moreover, it is possible to flag such queries as “activated” so their results are immediately visible when navigating to a portal page/work set containing the respective POWL iView. This way, the user has its custom “workload” right at hand (as it is the case in UWL with the user’s mandatory, externally “pushed” workload).

    For example , using POWL you can call a work list with

    1. Incomplete sales orders or a work list with

    2. Sales orders that are blocked for delivery by clicking the define query and result is just a click away.

    In General,

    1. POWL helps to create/edit/save multiple Custom queries as per user needs and load user specific default query at runtime or activate by clicking, thus save End user time to check multiple results at runtime.
    2. Its provides Query Auto-refresh functionality, Which auto refreshes data in an interval of time.
    3. POWL provide Query scheduler which enables us to provide the possibility to scheduled work list E.g. nightly work list build .
    4. POWL provide Authorities check to restrict user to POWL functionality like query creation/edit/deletion thus defining security roles from user to user.
    5. Furthermore POWL can be used to retrieve work items for custom workflow tasks in the POWL inbox processing work items, alerts and notifications.

    Dear Rohan,

    Thanks for the above steps. It has so many information.

    Could you kindly guide me to achieve the below mentioned scenario.

    We are using SAP SRM 7.0

    We are having RFx list screen which has few fileds in the selection conditions.

    Now, the requirement is I need to add/hide few fields in the selection condition.

    Because, by using the existing condition field our customers cannot control the required data.

    As a beginner, I could not exactly find the solution and also having little fear to handle standard WD component.

    Here is the component and View details.

    WD Component: POWL_UI_COMP

    View: MASTER_CONTENT

    Kindly provide me if you have any documents or any related materials.

    Thanks in advance.

      Hello Madhavan,

      You First Need to application ID for your application.
      This you can find by putting a breakpoint in cl_POWL_MODEL-> Initialize method.

      Form application ID, find the powl Type in POWL_TYPE transaction, from there you will get feeder.

      In feeder get_sel_crit method, you can do all this.

      Best regards,

      Rohit

    Hello!

    Thanks for share your knowledge.

    I am implementing your step by step guide and I found a mistake.

    Method GET_OBJECTS was write as GET_DETAIL_COMP. Is It  the same code?

    Best regards.

    • Method GET_OBJECTS

    METHOD IF_POWL_FEEDER~GET_DETAIL_COMP.
    E_DETAIL_COMP =
    ‘YEMPLOYEE_POWL_WD’.ENDMETHOD.

    • Method GET_DETAIL_COMP

          METHOD IF_POWL_FEEDER~GET_DETAIL_COMP.
           E_DETAIL_COMP =
    ‘YEMPLOYEE_POWL_WD’.
         
    ENDMETHOD.

    Hi Rohan,

    thanks for the guideline, however I don’t get something:

    How do you create a text field on Web Dynpro and pass it as selection parameter to POWL?

    I did create text field and in the action method do encode the parameter and pass the to POWL like this:

    CALL FUNCTION ‘POWL_ENCODE_SELPARA’

         EXPORTING

           i_selpara        = lt_query_params

           i_escape         = ‘\’ “_line

         IMPORTING

           e_selpara_string = lv_inbox_query.

       wd_this->fire_out_plg(

           applid = ‘CL_GT_AC_USERCONN’

           qname = lv_qname

           forallq = ‘X’

           powldeltarendering =

           qselpara = lv_inbox_query

           refreshq = ‘X’

           refresha = ‘X’

           srvgroup =

           ).



    The Problem is, that the selection parameter (encoded and passed tp POWL) don’t land in the get variable I_SELCRIT_VALUES of the Method GET_OBJECTS of the POWL Feeder Class… There I only have the paramtere defined in POWL.


    Whats missing?

    Hi,

    I followed all the steps indicated above and instead of database table I used a DSO table.

    But I am not getting the search panel i.e the panel where

    “Here, You can

      • Define New query (Define New query)
      • Change Query (Change Search condition)
      • Personalize (Set Layout , Remove query , Set default query etc)”.

      Also my requirement is to build a POWL screen where data can be manually entered and saved.


      This is my first time POWL and WD integration. Can anyone please help me.


      Thank you in advance.
