Help needed for automatic batch creation for by-products(PP-PI)

Question

Hi,
In the Goods Recpt tab in transaction COR1, we have a field for creating a batch manually for the header material. On clicking on create, a pop up is generated whch facilitates creation of batch for the header material.
At this point, if i go to the material list, I would like to see the same batch number ( same as header) written against the BY-Products.
Essentially, when i create a batch for the header material, it should also create a batch with the same number for the by-product and populate the same in the materials tab.
One important thing to note here is that when we click on create batch icon, the data is stored in a structure and the batch is actually created only when the process order is saved.
Please advise if this can be achived by some standard settings in SAP or do we need to change the standard code. If later is the case, please advise about the point where to insert the required code. I have found a user exit at the point where batch numbe is created manually.
Please advise.

Answer 1

As per SAP Batch definition Batch is the quantity or partial quantity of a certain material or product that has been produced according to the same recipe, and represents one homogenous, non- reproducible unit with unique specifications. So logically you cannot have same batch number for two materials.
If you want to find out the relation between batches of header material and by product that is produced during production, you can use Batch Information Cockpit.
To see batch details in Batch Cockpit (T-code: BMBC), You have activate Batch where used function in IMG using path : Batch management-->Batch Where used list --> make setting for batch where used list.
