Need to Process Large Internal Tables Efficiently

Question

I have two internal tables, T_EKKO(for PO Header data) and T_EKPO(for PO Item data). These tables carry data for 10 PO's with at least 1 line item in each one.
The requirement is to write the following fields on the result screen:
     Line 1: PO Number.-      
Line 2:PO Item, Article Number.
What is the most efficient way to do this?

Answer 1

Hi,
You can use parallel processing techinque..
Ex.
SORT T_EKPO BY EBELN.
DATA: V_TABIX TYPE SYTABIX.
LOOP AT T_EKKO.
  WRITE: / 'PO Number - ', T_EKKO-EBELN.
  READ TABLE T_EKPO TRANSPORTING NO FIELDS
                       WITH KEY EBELN = T_EKKO-EBELN
                       BINARY SEARCH.
  IF SY-SUBRC = 0.
Store the row number.
    V_TABIX = SY-TABIX.
     LOOP AT T_EKPO FROM V_TABIX.
Exit condition.
         IF T_EKPO-EBELN <> T_EKKO-EBELN.
           EXIT.
         ENDIF.
         WRITE: / 'PO item', T_EKPO-EBELP.
     ENDLOOP.
  ENDIF.
ENDLOOP.
Thanks,
