• What is the cause and solution for SAP error message WY060 - Plant & already assigned to supplier & ?

  SAP Error Message:
  
  WY060 - Plant & already assigned to supplier &
  
  Cause:
  This error occurs when you try to assign a plant to a supplier in SAP, but the plant is already assigned to another supplier in the system. In SAP, a plant can only be linked to one supplier for certain master data or processes, and attempting to assign the same plant to multiple suppliers violates this rule.
  
  Explanation:
  
  The message indicates that the plant you are trying to assign is already linked to a different supplier.
  This typically happens during vendor master data maintenance or when configuring supplier-plant relationships.
  The placeholders & in the message represent the plant and supplier codes involved.
  
  
  Solution:
  
  
  Check Existing Assignments:
  
  Use transaction codes like XK03 (Display Vendor) or MK03 (Display Vendor Purchasing Data) to check which supplier the plant is currently assigned to.
  Alternatively, check the table LFA1 (Vendor Master General Data) and LFM1 (Vendor Master Purchasing Data) or T024D (Plant Data for Vendor) to find existing plant-supplier assignments.
  
  
  
  Decide on Action:
  
  If the plant should be assigned to the new supplier, you must first remove or change the assignment from the old supplier.
  If the plant must remain assigned to the current supplier, you cannot assign it to another supplier.
  
  
  
  Remove or Change Assignment:
  
  If appropriate, update or delete the plant assignment from the old supplier using vendor master maintenance transactions (XK02, MK02).
  Then assign the plant to the new supplier.
  
  
  
  Consult Business Process:
  
  Confirm with your procurement or master data team whether the plant assignment should be changed.
  Sometimes, the restriction is intentional due to business rules.
  
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  XK01/XK02/XK03 – Create/Change/Display Vendor (General and Purchasing Data)
  MK01/MK02/MK03 – Create/Change/Display Vendor (Purchasing Data)
  ME21N – Create Purchase Order (may trigger this error if plant-supplier assignment is inconsistent)
  
  
  
  Tables:
  
  LFA1 – Vendor Master (General Section)
  LFM1 – Vendor Master Purchasing Data
  T024D – Plant Data for Vendor
  
  
  
  Notes:
  
  This error is common in scenarios where vendor-plant relationships are strictly controlled.
  Always ensure master data consistency to avoid procurement process disruptions.
  
  
  
  
  If you need further assistance, please provide the exact transaction or process where the error occurs, and the plant and supplier codes involved (if possible).
