Subcontracting for special stocks (project) batch determination

Dear gurus,

I would request your assistance successful the pursuing scenario:

- Special subcontracting script with relationship duty "Q" and point class "L"

- Both header worldly and constituent are acceptable arsenic Individual/Coll. Req = 1(Individual requirements only) successful MRP4 view. 

- Due to the supra mounting we are not sending the components to the subcontractor via ME2ON alternatively the components are kept nether peculiar stock, task banal nether the task for which subcontracting bid is besides created.

- With this acceptable up constituent are getting consumed from task banal erstwhile we bash GR for the subcontracting order.

- The constituent is marked arsenic batch managed and erstwhile GR is done to person the constituent nether task banal batch is created automatically

- Batch is not automatically assigned to the constituent successful the subcontracting bid and this is causing contented due to the fact that erstwhile we effort to GR the subcontracting bid we get mistake "Enter batch"

My question (I americium newby for batch absorption )

- When and however batch duty to the components should happen? I cognize this tin beryllium done manually successful the subcontracting order

- Can batch duty to the constituent beryllium automated? If yes should beryllium hap erstwhile subcontracting bid is created and the BOM is exploded oregon it should beryllium done during posting GR?

- If batch duty tin beryllium automated tin you delight supply measurement by measurement acquisition however I tin execute it?

I truly admit each inputs connected this topic.

Thanks successful advance.
