POWL feeder clas GET_FIELD_CATALOG does not work

Hi,

Copied SAP standard feeder class and tried to modify the layout through the feeder class GET_FIELD_CATALOG but it doesn't seem to work.

e_fieldcat_changed value is 'X' but some it doesn't get the fields from that method.

Even when I commented out the whole code in the method, it can somehow gets the data but in incorrect sequence.

My questions: Where does it get the fields from to be displayed ? And could it be overwritten somewhere and how to correct it so that I get the correct field sequence ?

I saw there's a discussion that it gets overwritted by method GET_OBJECTS ? I don't see it's possible.. because my final output in GET_OBJECTS method is different as well from the POWL output layout.

Thanks in advance.
