• What is the cause and solution for SAP error message PM204 - Table key &1 &2 &3 &4 entered already exists ?

  The SAP error message PM204, which states "Table key &1 &2 &3 &4 entered already exists," typically occurs in the context of the Plant Maintenance (PM) module when there is an attempt to create or modify an entry in a table where a record with the same key already exists. This can happen in various scenarios, such as when creating maintenance plans, work orders, or other related objects.
  Cause:
  The error is caused by a violation of the uniqueness constraint for a specific table key. The key components represented by &1, &2, &3, and &4 are placeholders for the actual values that make up the unique key in the database table. When you try to insert or update a record with a key that already exists, SAP raises this error to prevent duplicate entries.
  Solution:
  To resolve the PM204 error, you can take the following steps:
  
  
  Check Existing Records: 
  
  Use transaction codes like SE16 or SE16N to access the relevant database table and check if a record with the same key already exists. This will help you identify the conflicting entry.
  
  
  
  Modify the Key: 
  
  If you are trying to create a new entry, ensure that the key values you are using are unique. Modify the key values to avoid duplication.
  
  
  
  Update Instead of Create: 
  
  If you intended to update an existing record, ensure you are using the correct transaction or method to update rather than create a new entry.
  
  
  
  Consult Documentation: 
  
  Review the relevant SAP documentation or help files for the specific transaction or process you are working with to ensure you are following the correct procedures.
  
  
  
  Check Customizations: 
  
  If your SAP system has custom developments or enhancements, check if any custom logic is affecting the creation of records in the relevant table.
  
  
  
  Contact Support: 
  
  If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with SAP support for further assistance.
