GR Cancel (t-codel MBST) issue

Question

Hi All,
We have a problem as follows:
The idea GR/IR process is that all GR documents should not be able to reverse / cancel by T-code : MBST after IR done.
We have some documents have done GR/ IR, but still allow to reverse or cancel GR by T-code MBST. Some documents are not allowed to reverse / cancel by system. The error message is "Deficit of PU IR quantity XX.XXX EA". It is correct.
Remark : All GR qualitity and value = IR.
Anyone know why some GR documents allow to reverse / cancel by MBST after IR done ????
Thank You
Alex

Hi
System checks total GR qty vs total IV qty
if
1. Total GR qty == IR qty -- system will not allow to cancel GR
2. Total GR qty > IR qty -- system will all to cancel GR upto difference between (GR-IV)
System is not checking for specifc GR, IR is done or not.
