Based on the PR to PO process for stock items, I will like to confirm with CS on below:
Scenario1
For customer request delivery of all items in one shot delivery, the CS will activate the “complete delivery” check box in the SO header. And also ensure all line items have requirement type “KE” to trigger a back-to-back order
Scenario 2
For important projects or specific customer’s need that the CS needs to ensure stock availability, they need to ensure the line item has requirement type “KE” to trigger to a back-to-back order
Then the SCM will decide based on MD04 stock availability to perform stock transfer (from Un-restricted stock to Sales Order stock) or issue the back-to-back order.
Other than above two scenario, it is mandatory for CS to follow the MM setting during the SO creation
