  SAP Error Message:
  
  WY101 - Supplier &, pur. org. & not assigned to supplier hierarchy
  
  Cause:
  This error occurs when you try to process a transaction (such as creating or changing a purchase order, invoice, or other procurement documents) involving a supplier and purchasing organization combination that has not been assigned to a supplier hierarchy in SAP.
  In SAP, supplier hierarchies are used to group suppliers for reporting, approval workflows, or other business processes. If the supplier and purchasing organization are not linked to any node in the supplier hierarchy, the system cannot proceed with the transaction that requires this assignment.
  
  Explanation:
  
  The system expects that the supplier (vendor) and purchasing organization combination is assigned to a node in the supplier hierarchy.
  This assignment is necessary for processes that depend on supplier hierarchies, such as workflow approvals, supplier evaluation, or reporting.
  If the assignment is missing, the system throws the WY101 error.
  
  
  Solution:
  
  
  Assign Supplier and Purchasing Organization to Supplier Hierarchy:
  
  Go to the transaction or IMG path where supplier hierarchies are maintained.
  Assign the supplier and purchasing organization to the appropriate node in the supplier hierarchy.
  
  Steps:
  
  Use transaction S_ALR_87012086 (Display Supplier Hierarchy) or navigate via IMG:
  
  SPRO ? Materials Management ? Purchasing ? Supplier Hierarchy ? Define Supplier Hierarchy
  
  
  Find the relevant supplier hierarchy node.
  Assign the supplier and purchasing organization to this node.
  
  
  
  Check Supplier Master Data:
  
  Verify that the supplier master data is correctly maintained for the purchasing organization.
  Use transaction XK03 or MK03 to display supplier master data.
  Ensure the purchasing organization data exists and is active.
  
  
  
  Check Configuration:
  
  Confirm that the supplier hierarchy is active and correctly configured.
  Ensure that the business process requiring the supplier hierarchy assignment is correctly set up.
  
  
  
  If Supplier Hierarchy is Not Used:
  
  If your business process does not require supplier hierarchies, check if the system or custom code is enforcing this check unnecessarily.
  Consult with your SAP functional consultant or developer to adjust the logic or deactivate the check.

  Summary:

Assign the supplier and purchasing organization to the appropriate supplier hierarchy node to resolve the issue.
