How to capture service text with po items.

Dear Friends

I have two PO item 10 and 20 ( EKPO),  which have 4 and 2 services items in ESLL table. I have two internal tables and I want to merge this information in single internal table. I have tried following way, but didnt helped me much.

I have attached screen shot / code / expalaination of problem with this message.

I am requesting you to please explain me how I can make this code work-able. I will greatly appreciate your any help.

Thanking you

My Code

SORT it_ser by ebeln ebelp_ekpo ASCENDING.

LOOP AT IT_SER INTO WA_SER WHERE BSART = 'ZSRV'.

 

*      Service Line edition starts here.

           CALL FUNCTION 'BAPI_PO_GETDETAIL1'

             EXPORTING

               purchaseorder = wa_ser-ebeln

               services      = 'X'

             TABLES

               return        = it_return

               poservices    = it_services.

 

           IF it_services IS NOT INITIAL.

               AT NEW EBELP_EKPO.

               LOOP AT it_services INTO wa_services WHERE outl_ind NE 'X'.

                    wa_ser-menge_ekpo  = wa_services-quantity.

                    wa_ser-meins_ekpo  = wa_services-base_uom.

                    wa_ser-netwr       = wa_services-gr_price.

                    wa_ser-txz01_ekpo  = wa_services-short_text.

                    MODIFY it_ser FROM wa_ser.

                    CLEAR wa_services.

               ENDLOOP.

               endat.

           endif.

 

CLEAR: wa_services, it_services.

Please see the images. I want to add all the services with po details in single table.
