Linking Sales Order Issue Cost Distribution to Original Purchase Order in Standard Costing

Summary:

Using Standard Costing with a Back-to-Back transaction, we’re seeing unexpected Purchase Order connections in the cost distributions for a sales order issue.

Content (please ensure you mask any confidential information):

1. We create a Back-to-Back transaction where a sales order line creates a requisition line that subsequently creates a PO line. There’s a direct connection between the Sales Order and the PO at this stage.
2. The PO is received and the item is shipped to fulfill the Sales Order.

When reviewing cost accounting distributions for the sales order issue, I noticed a different PO linked to the sales order shipment—not the original PO created through the Back-to-Back process.
