Extract CE1XXX COPA table in BW

Hi I need to extract CE1XXX COPA table into BW, but will not use CE2xxx, CE3xxx and CE4XXX tables.

Can i Extract only CE1XXX Copa table only, Also can i enable generic Delta for using CE1XXX Copa table . I can see ERDAT is available , is ERDAT the correct Field to enable Generic delta from CE1XXX Copa table.

Thanks in advance..
