HI,
As per PP Work flow follow as below SEQUENCE,
1.Take GR 101 for confirmed Goods of 60 Kgs.
2. Take GI Reversal 262 for remaining goods of 40 Kgs.
In your case even though the excess qty is allowed for 262 it'll be captured in COGI with error msg.
REWARD POINTS IF USE-FULL.
Thanks With Regards,
Dinesh V.
