Batch to be transferred from the Production Order

Hi Experts,

I have a requirement as follows:

1. We use Standard Make to Stock Scenario.

2. The Production order is created for the FG material. The components for the FG are Batch Managed and externally procured.

3. There are only 3 Batches for the components. no new will be created (fixed).

4. After the MRP run, The Purchase Requisitions will be created for the components and the rest of the procurement process will be carried.

5. The requirement is that the Batch should be automatically filled in the Purchase Requisition and should require no manual intervention in the PO, MIGO processes from the end-user.

Kindly let me know the possibilities to incorporate the batch at the Production order for the components.

Thanks in advance
