I have a user exit for data coming from R/3. I am a little confused whether the field REBZG is being filled in this code or is just checking the original and clearing invoices and calculating the ammounts? I am sorry to ask the same question again. But Its very important for me to get things clear about this REBZG. Here is the code:
DATA: DOC_TO_LOOK like FS_DTFIAR_3-BELNR
Pickup clearing document into internal table.
SELECT * FROM BSEG INTO TABLE ZCLEAR_DOC
WHERE BUKRS = FS_DTFIAR_3-BUKRS
AND BELNR = FS_DTFIAR_3-AUGBL
AND GJAHR = ZFISYEAR.
Calculate amount to clear by looking for residual items.
Find original invoice: Invoice reference or current item.
if FS_DTFIAR_3-REBZG = ''.
DOC_TO_LOOK = FS_DTFIAR_3-BELNR.
DOC_TO_LOOK = FS_DTFIAR_3-REBZG.
