Hi,
As i understand that you have taken the data into the internal table.
Now at field level routine you just need to read that table and assign the value to the infoobject.
Syntax will be like that
Read table disc_con_tabl into disc_con_wa with key 0UC_DISCACT = source_fields-0UC_DISCACT.
If sy-subrc = 0.
Result = disc_con-wa- /BIC/Z_DSACDAT .
Endif.
Hope this helps.
Regards,
AL
