The standard SAP Business One lets you apply the approval template to Sales A/R and/or Purchasing- A/P documents only or to Inventory related documents only.
With Production Approval installed, it enhances the standard SAP Business one Production Order function by adding the approval process.
No amendments can be made once the production order has the status of approved.
The User sends the production order for approval and is unable to release the production order until it has been approved. The User will receive a message on the status.
