BDC error for MM02

The BDC that I have created for the transaction MM02, stops for some records while for some records it runs perfectly fine. When I give the mode as 'E' or 'A' the BDC is stopped for the status message - "Reorder point considered only with reorder point or time-phased planning", which is not an error. If we press an Enter manually(without changing anything) then the transaction executes successfully. But when mode 'N' is given then the BDC skips the record and move ahead with next record. Also no error or status message is captured.
