  SAP Error Message:
  WY134 - Supplier & is assigned to plant & which no longer exists
  
  
  Cause:
  This error occurs when a supplier (vendor) master record is assigned to a plant that has been deleted or is no longer valid in the system. Essentially, the system is trying to reference a plant in the vendor master data that does not exist in the current plant master data.
  
  Explanation:
  
  In SAP, vendor master data can be maintained at different organizational levels, including company code and purchasing organization.
  The vendor may also be assigned to specific plants for procurement purposes.
  If a plant is deleted or deactivated in the system but the vendor master data still references that plant, this inconsistency triggers the WY134 error.
  This often happens after plant deletions, system cleanups, or data migrations where vendor assignments were not updated accordingly.
  
  
  
  Solution:
  
  
  Check Vendor Master Data:
  
  Use transaction XK03 (Display Vendor) or MK03 (Display Vendor Purchasing Data).
  Check the plant assignments under
