Import PO Process

Hi,

We are following the below mentioned process for regular procurement:

1. Capture of excise invoice (part 1)

2. Entry of Goods Reciept (MIGO)

3. Posting of excise invoice (part 2)

4. Invoice verification (MIRO)

Because of this process, the GR- based IV indicator has been made mandatory using a user exit in Vendor master and a BADI is active in MIRO allowing entry of invoice only if a GR is posted.

In case of imports procurement, we create a single PO initially and then create multiple POs for multiple consignments. The entry of excise and GR follows the same sequence as regular procurement.

How can I go about implementing import PO process where I can use the initial PO for multiple consignments?
