Subcontracting for special stocks (project) batch determination

[dave1987]

Dear gurus,

I would need your help in the following scenario:

- Special subcontracting scenario with account assignment "Q" and item category "L"

- Both header material and component are set as Individual/Coll. Req = 1(Individual requirements only) in MRP4 view. 

- Due to the above setting we are not sending the components to the subcontractor via ME2ON instead the components are kept under special stock, project stock under the project for which subcontracting order is also created.

- With this set up component are getting consumed from project stock when we do GR for the subcontracting order.

- The component is marked as batch managed and when GR is done to receive the component under project stock batch is created automatically

- Batch is not automatically assigned to the component in the subcontracting order and this is causing issue because when we try to GR the subcontracting order we get error "Enter batch"

My question (I am newby for batch management )

- When and how batch assignment to the components should happen? I know this can be done manually in the subcontracting order

- Can batch assignment to the component be automated? If yes should be happen when subcontracting order is created and the BOM is exploded or it should be done during posting GR?

- If batch assignment can be automated can you please provide step by step instruction how I can achieve it?

I really appreciate all inputs on this topic.

Thanks in advance.
