Multiple Receipts against PO Qty=1

Dear All,

Need your advice as to how do we handle following scenario:

• PO created for say a capital item CAP1 to  a supplier SCAP1 for 1 quantity.
• However SCAP1 is not going to supply it as 1 complete quantity as he is a dealer and not manufacturer.
• He will be procuring various spares/assembly parts from various other suppliers.
• These spares/assembly parts will be delivered to our premises along the other suppliers excise invoices based on which I will be availing excise credit.
• After all the spares/parts are supplied, SCAP1 will raise his invoice for 1 qty. He will not charge excise but only local VAT or CST.
• My contract/PO is with SCAP1, I am not going to pay anything to the other suppliers.

Now the issue is,

• Since PO is of 1 quantity, how do I inward those spares/parts against the PO which is issued to SCAP1.
• Since I will be availing excise credit based on the other supplier's invoices, I need to capture the details of all those invoices during MIGO.

Please suggest.

Thanks & Regards,

Husein N T.
