  SAP Error Message:
  WY179 - Supplier &1 is blocked for all purchasing organizations
  
  
  Cause:
  This error occurs when you try to create or process a purchasing document (like a purchase order) for a supplier who has been blocked for all purchasing organizations in the system. The supplier master record has a block indicator set, which prevents any purchasing activity with that supplier across all purchasing organizations.
  
  Explanation:
  
  In SAP, suppliers (vendors) can be blocked for purchasing either for specific purchasing organizations or for all purchasing organizations.
  When a supplier is blocked for all purchasing organizations, no purchase orders or related documents can be created or processed for that supplier.
  This block is usually set to prevent procurement from suppliers who are inactive, unreliable, or under review.
  
  
  How to Check:
  
  Go to transaction XK02 (Change Vendor) or MK02 (Change Vendor Purchasing Data).
  Enter the vendor number.
  Check the purchasing data tab for the block indicator.
