3364431 - How to link a Purchase Order to a Sales Order, for a To-Stock scenario


Purchase Order is not getting linked to a Sales Order 


Sales Order is not getting created from a Purchase Order for To-Stock scenario


SAP Business ByDesign 

Reproducing the Issue

  1. Go to Purchase Order work center
  2. Go to Purchase Orders view
  3. Select the Purchase Order number and open items tab
  4. Select a line item, Account assignment tab is not available 
  5. In the document flow tab of the Purchase Order, no Sales Order is linked to this Purchase Order.


The Purchase Orders are for To-Stock items. To-Stock items will not have an Accounting Assignment. In a To-Stock Procurement scenario, no Account Assignment is done to a Cost Center or any other cost object like Sales Order, Project, etc... In such a case, the postings happen to the G/L accounts according to the Account Determination group maintained for the corresponding material and supplier. The costs are not explicitly incurred against any cost object and hence one does not see the cost object ID in the Journal Entry. This is the correct behavior. The postings happen to the inventory account of the business residence where the material is going to be stocked.


The only scenario where we have a direct link between a Sales Order and a Purchase Order is the Third-Party-Order Process (TPOP), but here the material never touches the own warehouse, but is directly shipped from the Supplier to the Customer.

Another way of establishing the link between Sales Order and purchase Order is by using the product specification as outlined in this blog post Modelling make-to-order using product specifications | SAP Blogs . This approach will also work for Purchasing scenarios, not just only for Production scenarios.
