*check while mb1b 309*

Hi,

we have made a z program for packing and dispatch system.

now users are doing the posting of the stocks from material to material that are already packed, so when User is trying to do the PGI system is showing the insufficient stock. so i need to keep a check in the std Tcode MB1B mvt 309, system should through an error saying that this material batch is already packed.

Could you please suggest me me how to handle this issue.

Regards

Ravi Kumar
