I have spent many hours in first analysing these things and then implemented them for specific requirement .

So I would like to share my knowledge here .


Worklists for SPP is based on POWL concept . Therefore adding new query requires to follow POWL procedure.

As Planner’s worklist in SPP uses its own standard web dynpro component, we don’t need to create web dynpro component

for displaying it. We just need to take care about feeder class . Detailed steps can be find as below :


1.     Create a Feeder class ex : ZCL_FEEDER_PRE_FORECAST.

2.     Inherit IF_POWL_FEEDER, IF_POWL_FEEDER_EXT and /SAPAPO/IWCI_PUIA_POWL_DETAIL interface in feeder class (refer below screenshot)

         PIC1.png

  So you will get all methods of mentioned interfaces as shown in below fig.   

   PIC2.png

3.     For defining selection criteria for custom query, we need to write code in IF_POWL_FEEDER~GET_SEL_CRITERIA .

        Here we must need to pass selection to changing parameter ‘C_SELCRIT_DEFS’ .

4. Field catalogue and logic for fetching data could be defined in IF_POWL_FEEDER~GET_FIELD_CATALOG and IF_POWL_FEEDER~GET_OBJECTS

    as per POWL concept .

5. For defining various buttons in queries over Planner’s worklist, We can use method IF_POWL_FEEDER~GET_ACTIONS of feeder class as

    shown below .

    pic4.PNG

      Action id will be assigned to button as defined in method IF_POWL_FEEDER~GET_ACTIONS .

      for assigning action against particular button, we can write code in method IF_POWL_FEEDER~HANDLE_ACTION referring

      respective action id.

     

      For Navigation over the GUI tcode or URL we can write logic as shown below :

      DATA :           lt_tihttpnvp TYPE tihttpnvp,

                      ls_ihttpnvp  TYPE ihttpnvp,

                      lv_url_l     TYPE string,

                      lo_url       TYPE REF TO cl_url,

                      lv_host_l    TYPE string.


          

      CREATE OBJECT lo_url.

    *     Pass paramerters

           ls_ihttpnvpname = ‘BALHDR-OBJECT’.

           ls_ihttpnvpvalue = ‘ZSPP_DM’.

           APPEND ls_ihttpnvp TO lt_tihttpnvp.

           CLEAR : ls_ihttpnvp.

           CLEAR : lv_url_l.

    *    Create URL

           CALL METHOD lo_url->its

             EXPORTING

               transaction = ‘SLG1’       ” name of tcode

               query_parms = lt_tihttpnvp

             RECEIVING

               url         = lv_url_l.

    *       Call the URL

           IF lv_url_l IS NOT INITIAL.

             CALL METHOD cl_nwbc=>url_launch

               EXPORTING

                 url = lv_url_l.

           ENDIF.


6.   For defining UI components in feeder class, we can write code in method IF_POWL_FEEDER_EXT~GET_UI_PERIPHERALS .

      As in given example, it is required to display another web dynpro component as a pop-up on action of button .

      Other than pop-up, we can display web dynpro component in various ways. You can check this method for details.

      pic5.PNG

      In HANDLE_ACTION method, we can call this by writing below code against respective action id .

     

        e_portal_actionsfire_wdevent = abap_true.

         e_portal_actionslaunch_editor = abap_true.

7.  For showing detail component for particular record in POWL. It is required to give web dynpro component which will be used

     for showing detailed structure . Standard details component is  /SAPAPO/PUIA_POWL_DETAIL .

     We can use it in method IF_POWL_FEEDER~GET_DETAIL_COMP  as below code

         e_detail_comp = ‘/SAPAPO/PUIA_POWL_DETAIL’.

8. After creation of feeder class, we need to create Powl type and assign it to standard application id for planner’s worklist

   which is SPP_PLANNER .

   We can create powl type through table POWL_V_TYPE (tcode : SM30) . While creating Powl type we need to provide feeder class.

   In our example we will provide ZCL_FEEDER_PRE_FORECAST .

9. Then we will create query id.  In query id, we will provide visible possibility of selection parameters and link powl type to query id .

10. In table POWL_V_TYPE_R, we can assign powl type id to application id & assign role to it (if required) .

     pic6.PNG

11.  As planner’s worklist have multiple queries, so either we need to create our own category for displaying query in planner’s worklist

      or we can use existing categories . I will show difference in both later in this document .

      In our example, we are creating new category from table POWL_V_CAT .

     And we can map this category to planner’s worklist by using tcode    POWL_QUERYR . Here we provide application id which is

     SPP_PLANNER for planner’s worklist and our own powl query. Here we can also provide query sequence and other details .

12. Now for showing pop-up (already declared in feeder class ) we need to define a web dynpro component which we have provided in feeder

     class. In our example it is ZWD_PRE_FORECAST_POP_UP .

       For this create a web dynpro component. In our example we are showing alv list/ table as pop-up .

       we must need to implement following components in our own web dynpro .

       pic8.PNG

         And also implement interface as shown below :

         pic9.PNG

            In component controller we need to create structure for alv list/table .

   pic7.PNG

Then we will create nodes in context of main view and map it to component controller’s node .

  pic10.PNG

And in view itself create table in layout table and bind it  .

    pic11.PNG

Create shown event for action in component controller .

pic12.PNG

write the code for populating table in method SET_SELECTED_DATA of component controller and in other method according to requirement .

we are writing in SET_SELECTED_DATA because we are getting values of selected rows over POWL in this method .

13. For displaying detail component over powl .

     we need to do setting in customising using path : Advanced Planning and Optimization-> Supply Chain Planning ->Service Parts Planning (SPP)

      ->Monitoring ->Detail Component for Planner’s Worklist and Customer’s Worklist ->Maintain Detail Component .

    We can define detailed component structure and logic method to fill that structure and other settings here .

Now in that logic method we need to following parameters :

    pic13.PNG

Here ES_RESULT is output structure which you have provided in SPRO path .

and in feeder class against that respective button, you need to write following code where <fs_results> is selected row over powl :

READ TABLE c_result_tab ASSIGNING <fs_results> INDEX i_action_index.

       IF sysubrc IS INITIAL.

*       Buffer customizing

         /sapapo/cl_puia_powl_detail=>buffer_detail_cmpt_config(

             EXPORTING

               iv_applid  = i_applid

               iv_type    = i_type

             IMPORTING

               et_message = e_messages  ).

         IF e_messages IS NOT INITIAL.

           RETURN.

         ENDIF.

*       Set selection parameters for detail component

         ls_selectionapplid            = i_applid.

         ls_selectiontype              = i_type.

         ls_selectionactionid          = i_actionid.

         ls_selectionkeyfieldsmatnr   = <fs_results>matnr.

         ls_selectionkeyfieldslocnofr = <fs_results>locnofr.

         ls_selectionkeyfieldslocnoto = <fs_results>locnoto.

         ls_selectionkeyfieldsvrsioex = space.

         GET REFERENCE OF <fs_results> INTO ls_selectionselection.

         /sapapo/cl_puia_powl_detail=>set_selection( is_selection = ls_selection  ).

*       Set lead selection

         /sapapo/cl_puia_powl_detail=>set_lead_selection( EXPORTING iv_action_index = i_action_index CHANGING cs_selected = c_selected ).

         e_selected_changed = abap_true.

*       Update side panel selection after lead selection update

         /sapapo/cl_puia_bcv_assistance=>set_selection( is_selection = ls_selection ).

       ENDIF.


For reference you can check standard class : /SAPAPO/CL_FEEDER_CRITICAL_PRD in this context .


14. Execution : transaction (/SAPAPO/SPP_PLN_LIST) .

   pic15.PNG

      Here in second query we can see DEMAND CLEANSING, it is coming from our own category and under this we have

      mapped our powl query which is PRE FORECAST .

      We can also map our custom query against standard category .

     

      In the query, we can see various buttons we are coming from method IF_POWL_FEEDER~GET_ACTIONS from feeder

      class and action for them is linked in method IF_POWL_FEEDER~HANDLE_ACTION .


      One important thing to note is that Planner’s worklist (SPP) should always be executed through NWBC otherwise

      itwill not come with its full functionality and could miss navigation property etc .

     

     If we click on buttons for navigation .It will navigation to desired screen as defined against action id in handle_action method .

     pic16.PNG

          By clicking on button for pop-up, it will show the web dynpro component which we have developed for showing ALV .

     pic17.PNG

      Detailed Component will be shown like below :

   pic18.PNG

       In above mentioned methods and paths, there are many more options available . You can check in detail based on requirement .
