• What is the cause and solution for SAP error message WRF_AT111 - Relationship between alloc. table (&1, item &2) and PO is not unique ?

  SAP Error Message:
  
  WRF_AT111 Relationship between alloc. table (&1, item &2) and PO is not unique
  
  Meaning / Cause
  This error occurs when the system detects that the relationship between an allocation table entry and a Purchase Order (PO) is not unique. In other words, there are multiple entries or links in the allocation table for the same PO item, which should be unique.
  Typically, this happens in scenarios involving:
  
  Workflow or Release Strategy configurations where allocation tables are used to link PO items to certain conditions or rules.
  Custom or standard allocation tables that map PO items to other objects (e.g., cost centers, projects, or other controlling objects).
  Data inconsistencies or duplicate entries in the allocation table for the same PO and item combination.
  
  
  Detailed Explanation
  
  The allocation table (&1) contains entries that link PO items (&2) to certain controlling or workflow elements.
  The system expects a one-to-one relationship between the allocation table entry and the PO item.
  If multiple entries exist for the same PO item, the system cannot determine which one to use, leading to this error.
  
  
  Common Causes
  
  Duplicate entries in the allocation table for the same PO and item.
  Incorrect or incomplete configuration of allocation tables or workflow rules.
  Data corruption or manual changes in the database leading to multiple links.
  Custom developments or enhancements that incorrectly create multiple entries.
  
  
  How to Analyze
  
  Identify the allocation table name (&1) and the PO item (&2) from the error message.
  Check the entries in the allocation table for the given PO and item.
  Use transaction SE16/SE16N or SE11 to view the allocation table data.
  Look for duplicate or multiple entries for the same PO and item.
  Check related customizing or workflow configuration that populates this table.
  
  
  Solution / Resolution
  
  
  Remove duplicate entries:  
  
  Delete or correct duplicate entries in the allocation table for the PO and item.
  Ensure only one unique entry exists per PO item.
  
  
  
  Correct configuration:  
  
  Review the configuration of allocation tables and workflow or release strategy.
  Make sure the rules or conditions do not create multiple entries for the same PO item.
  
  
  
  Data consistency check:  
  
  Run consistency checks or reports to identify and fix data inconsistencies.
  If necessary, involve Basis or ABAP team to clean up the data.
  
  
  
  Custom code review:  
  
  If custom developments are involved, review the code that inserts or updates allocation table entries.
  Fix logic to prevent multiple entries for the same PO item.
