Reproducing the Issue

  1. Go to Purchase Requests and Orders work center
  2. Select the common task New Purchase Order
  3. Enter the supplier ABC
  4. You receive the warning message Party Seller with ID ABC blocked, however since it is a warning message, you are still able to post the document.


This is an expected system behavior. Even setting the status of a supplier as Blocked, the system still allows the users to create documents with inconsistent status.

  1. Go to Supplier Base work center
  2. Go to Suppliers view

  5. Check the box Purchasing Blocked
  6. Save the changes
