• What is the cause and solution for SAP error message WY012 - Partner & not maintained for purchasing organization & ?

  The SAP error message:
  WY012: Partner & not maintained for purchasing organization &
  
  Cause:
  This error occurs when a required partner function (such as Vendor, Contact Person, or any other partner role) is not maintained or assigned for the specified Purchasing Organization in the system. In SAP MM (Materials Management), partner functions must be properly defined and linked to purchasing organizations to ensure correct processing of purchasing documents.
  For example, if you are creating or processing a Purchase Order or a Contract and the system expects a partner (like a Vendor or a Contact Person) for the purchasing organization but cannot find it, it throws this error.
  
  When does it occur?
  
  During creation or processing of purchasing documents (Purchase Requisition, Purchase Order, Contract, Scheduling Agreement).
  When the partner function is mandatory but missing for the purchasing organization.
  When customizing partner functions for purchasing organizations is incomplete or incorrect.
  
  
  Solution:
  
  
  Check Partner Functions in Customizing:
  
  Go to SPRO ? Materials Management ? Purchasing ? Partner Determination ? Set Up Partner Determination.
  Verify that the partner function (e.g., Vendor, Contact Person) is assigned to the relevant purchasing document type and purchasing organization.
  Ensure that the partner function is maintained as mandatory or optional as per business requirements.
  
  
  
  Maintain Partner Data for Purchasing Organization:
  
  Go to transaction ME22N (Change Purchase Order) or relevant transaction.
  Check the partner tab to see if the required partner is maintained.
  If missing, add the required partner for the purchasing organization.
  
  
  
  Maintain Vendor Master Data:
  
  Ensure that the vendor master record has the correct purchasing organization data maintained.
  Use transaction XK02 or MK02 to check and maintain vendor master data.
  Verify that the vendor is assigned to the purchasing organization.
  
  
  
  Check Partner Determination Procedure:
  
  Verify the partner determination procedure assigned to the purchasing document type.
  Make sure the procedure includes the required partner functions.
  
  
  
  If Customizing is Correct but Error Persists:
  
  Check if any user-exits or BAdIs are modifying partner data.
  Debug the partner determination logic if necessary.
