RSEG table fields SPGRP and SPGRM are not populating for invoice having both values as 'X'.

Hi Seniors,

I have written a query on RSEG table but fields SPGRP and SPGRM are not populating in structure not even in variables for the invoice which have both the values for SPGRP and SPGRM as 'X'. Means for invoice which are blocked by both price and quantity. this query in written in a method of Bussiness Object ZBUS2081 and is release.

Please guide me to solve this puzzle.

Thanks in advance.
