Error while posting UD in QA32

Hi all,

While posting usage decision in QA32, I am getting the below mentioned error message:

"Of the required quantity of material BJ032050B0101, 100 PC remain(s) open. Message M7 389".

Of the 7000 PCS I am posting 6900 PCS to unrestricted stock and 100 PCS to return delivery as the 100 PCS are rejected during Qlty inspection.

By doing so I am getting the above mentioned error message.

Can anyone tell me what could be probable reason(s). Also please suggest me solution for the problem as it is important I resolve this issue at the earliest as it is creating lot of problem and unable to do stock posting for the kind of situation I mentioned above.

Regards

V. Srinivasa Ranganath
