I've gotta unique requirement. I need to write a BDC for a custom defined HR infotype, that needs to populate the fields in the screen based on the values from some other fields in the same screen. I make it clear here that the data of other fields are not in the database tables. I need to read the fields of the screen dynamically which i can do using some FM.
But since this is a BDC with CALL TRANSACTION, I cannot read a screen field that is available only in the future (after call transaction) coz the values of the itab needs to be populated well before that. Has anyone gotta solution??
