FM Call within EXIT_SAPLEINM_002- INCLUDE ZXM06U02- Read Code

Question

Hi,
Im calling FM RV_PRICE_PRINT_ITEM in EXIT_SAPLEINM_002 ( INCLUDE ZXM06U02). Please find part of code below:
DATA: tkomv type komv occurs 0 with header line,
      tkomvd type komvd occurs 0 with header line,
      tkomk type komk,
      tkomp type komp.
  WHEN 'E1EDP19'.
    LOOP at int_edidd into x_edidd.
      IF x_edidd-segnam = 'E1EDK01'.
        L_E1EDK01 = x_edidd-sdata.
        EXIT.
      ENDIF.
    ENDLOOP.
    L_E1EDP19 = int_edidd-sdata.
    IF L_E1EDP19-IDTNR <> '' AND L_E1EDP19-KTEXT <> '' .
      SELect single umrez into v_umrez from ekpo where ebeln = L_E1EDK01-BELNR
                                                 and matnr = L_E1EDP19-IDTNR.
      GET PARAMETER ID 'BSP' field bsp.
      CLEAR: tkomv,
             tkomvd.
      select single * from ekpo where ebeln = L_E1EDK01-BELNR
                               and ebelp = bsp.
      select single * from ekko where ebeln = L_E1EDK01-BELNR.
      tkomk-belnr =  ekko-ebeln.
      tkomk-mandt = ekko-mandt.
      tkomk-kalsm = ekko-kalsm.
      tkomk-kappl = 'M'.
      tkomk-waerk = ekko-waers.
      tkomk-knumv = ekko-knumv.
      tkomp-kposn = ekpo-ebelp.
   CALL FUNCTION 'RV_PRICE_PRINT_ITEM'
    EXPORTING
     COMM_HEAD_I       = tkomk
     COMM_ITEM_I       = tkomp
      LANGUAGE          = 'E'
    IMPORTING
      COMM_HEAD_E       = tkomk
      COMM_ITEM_E       = tkomp
    TABLES
     TKOMV             = TKOMV
     TKOMVD            = TKOMVD.
   LOOP AT TKOMV.
   IF TKOMV-KSCHL = 'ZD05'.
          select single * into v_konp from konp where knumh = tkomv-knumh.
          kbetr = v_konp-kbetr / 10.
   ENDIF.
If I test FM RV_PRICE_PRINT_ITEM in SE37 with the values Im supplying, I was able to read data. But if its inside the exit, table TKOMV doesnt contain any entries.
Is there anything wrong with this?
Also, how do I debug this exit in IDOC_OUTPUT_ORDERS? I have setup EDI for this,  and Im just using me22n messages to output idoc.
Please help.
Thanks.
Kenny

Hi Kenny,
Check in debug mode whether export parameter tkomk and tkomp are populated.
You can debug from ME22N. after changing the PO, before you save it start debugging, ie., give '/h' in the command and then click save button.
Once you enter there, click settings, and enable update debugging, after that click breakpoints in the menubar, click breakpoint at, select function module.
In the pop-up you enter  "EXIT_SAPLEINM_002". then give F8.
It will stop you in the first screen of the exit.
Incase the control remains in std program after your F8, try repeating the above step, it will take you to the exit.
Hope this helps,
