Raw Material Batched from Vendor and Serialized in house

Dear Seniors,

We have a process in which we are purchasing raw materials which are coming batched from Vendor.

In house, we serialize them.

We want to be able to specify the Vendor Batch and Serial Number in the Goods Receipt (MIGO).

The challenge we are facing is that if we mark the material batch and serialized in the material master, then the Batch field is mandatory in the Goods Receipt. We want to be able to mention only the Vendor Batch

Please let me know your suggestions about how you would solve this challenge.

Thank you,

Alex
