Thanks for your reply.

No my questions is different, its not depends in manufacturing(MRP) flow.

we need to do using internal transfer or inventory adjustment.

Out of the bow there are 2 options:

1. If it is a product you are receiving from a supplier for example, you can link it to a BOM of type KIT. Upon receipt of the product A, Odoo will split it into B & C.

2. If it is a product you currently have in stock under name A, then you need to disassemble it usin gan existin goption in the manufacturing applicatio. Go to Manufacturing > Operations > Unbuild Order and specification the locations. See picture:

I believe he's asking for mrp by-product.
