Hi,
Maintain the "sc vendor" indicator along with the subcontract vendor in the PO - delivery address tab.
Once you post the GR for the PO, the movement type will be 101 O, which will post the stock to subcontract vendor (similar to 541). Check the stock in MMBE.
You may pay the vendor after posting the GR (GR based IV).
If you want to capture the excise invoice for the above GR, follow the path: SPRO - Logistics General - Tax on Goods Movements - India - Business Transactions - Incoming Excise Invoices - Specify Which Movement Types Involve Excise Invoices. Here, maintain 101 O movement.
Regards,
AKPT
