An SAP Consultant

The below function modules are used to get the manager

• RH_GET_LEADING_POSITION :  Employee number or Employee User ID or Position or Org.Unit are passed as Object to function module.

• Use syntax addition "EXPORTING LIST TO MEMORY AND RETURN" to SUBMIT statement. This addition stores the basic list for the program accessed in the ABAP Memory. It can only be used together with the addition AND RETURN.The list is stored in the ABAP Memory as an internal table of the row type ABAPLIST. ABAPLIST is a structured data type in ABAP Dictionary.
• Use the function module LIST_FROM_MEMORY to load the list from the ABAP Memory to an internal table of the row type ABAPLIST.
• Use the function module LIST_TO_ASCI to convert the content of an internal table of the row type ABAPLIST to ASCII representation.
• Please check the below screen shots to see data in table before and after LIST_TO_ASCI function module is used. 

• Data is in pipe delimited. So loop the internal table and split the row type into corresponding fields. 
• Sample code to convert ASCI data to internal table

LOOP AT IT_WGTY_REP INTO WA_WGTY_REP.
        CHECK SY-TABIX GT 3 AND SY-TABIX LT LV_TOT_RECS.
        IF SY-TABIX = 4.
          SPLIT WA_WGTY_REP AT '|' INTO LV_DUMMY01
                                        LV_DUMMY02.
          IF LV_DUMMY02 CS 'List Contains no data'.
            EXIT.
          ENDIF.
        ENDIF.
        " Split pipe delimited data
        SPLIT WA_WGTY_REP AT '|' INTO LV_DUMMY01
                                      WA_ALV_OUTPUT_C-PERNR
                                      LV_DUMMY02
                                      WA_ALV_OUTPUT_C-FPPER
                                      WA_ALV_OUTPUT_C-PAYDT
                                      WA_ALV_OUTPUT_C-LGART
                                      WA_ALV_OUTPUT_C-LGTXT

                                      LV_DUMMY03.

        APPEND WA_ALV_OUTPUT_C TO IT_ALV_OUTPUT_C.
        CLEAR  WA_ALV_OUTPUT_C.
      ENDLOOP.

• Get all pending work items from table SWWWIHEAD(Header Table for All Work Item Types).

 "Get all pending work items
  SELECT WI_ID WI_TYPE WI_STAT TOP_WI_ID
    FROM SWWWIHEAD
    INTO TABLE IT_PLVE_WITEMS
   WHERE WI_TYPE     = 'W'
     AND WI_STAT     = 'READY'
     AND WI_RH_TASK  = C_WORFLOW_TASK.

• Get the work items assigned to user using table SWWUSERWI.

IF IT_PLVE_WITEMS IS NOT INITIAL.
    "Current Work Items Assigned to a User
    SELECT USER_ID WI_ID TASK_OBJ
      FROM  SWWUSERWI
      INTO TABLE IT_WI_AGENT
      FOR ALL ENTRIES IN IT_PLVE_WITEMS
     WHERE WI_ID     = IT_PLVE_WITEMS-WI_ID
       AND TASK_OBJ  = C_WORFLOW_TASK
       AND NO_SEL    = SPACE.
  ENDIF.

• Based on two tables, we can filter work item for user.

• Go to Workflow log and click on the top-level work item as shown below.

• Use menu path GOTO->Technical Work Item Display. 

• Use menu path Edit->Change. 

• Click Execute next to Complete Manually. 

• Status changed to Logically Deleted.

Steps to forward work item

• Go to SWIA transaction code. 
• Enter the work item ID and Execute. 

• Select work items and Click on the Administrator Forward icon. 

• Enter the user name in the popup to whom you want to forward the work item and continue.

We set workflow status to Logically deleted, if the (sub) workflow is no longer required or meaningful.

Repetitive structures in HR denotes the table which has the same type of field structures(which stores same kind of values). For example, Table for Basic Pay Infotype 0008 is PA0008. This table stores all the wage types assigned to an employee in its fields LGAXX,  BETXX,  ANZXX,  EINXX and OPKXX. Here XX denotes the number 01-40. These fields are repeated for 40 times, as it is defined in SAP system(We can maintain 40 different wage types for an employee in Standards).
