Deleted Batch in Production order

Dear SAPeers,

I am trying to use a batch that has been deleted both at plant level as well as storage location level in the production order.

At the time of using a deleted batch a warning message pops up stating the batch is deleted but it still allows us to create and release the production order. I have made this warning message into an error message. But the error message does not reflect at the time of creation of production order it comes at the time of goods issue to production order.

But the components that have been assigned deleted batches also have backfluch indicator. So we need not issue these components using the goods issue transaction MB1A. While doing operation confirmation itself the components are picked up. They also come with the deleted batch. But they allow posting without giving any error or warning.

My question is how do we prevent deleted batches to be accepted at the time of production order creation. Secondly even if it allows at the time of creation of production order how do we stop it at the time of confirmation.

Thanks and Regards
