RFBIBL00 - profitability segment load problem

I try to create BDC using the program RFBIBL00, but encountered two problems:
   First: No batch input data for screen SAPLKEAK 0300
   -->Soulution: passing the value to RKE_BUKRS(http://forums.sdn.sap.com/thread.jspa?threadID=1225693).
   second: field dkacb-ximky does not exist
   -->Soultion: populate all the fields in BBSEG: if the field value is empty, fill '/' to the field.
