• What is the cause and solution for SAP error message RSDD_LM003 - Provider '&1' is used as a union more than once ?

  The SAP error message RSDD_LM003 indicates that a particular provider (in this case, a data source or InfoProvider) is being used multiple times in a union operation within a query or a data model. This situation can lead to ambiguity in the data retrieval process, as the system cannot determine how to handle the duplicate references to the same provider.
  Cause:
  The error typically arises in scenarios where:

  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Query Definition: 
  
  Open the query in the Query Designer.
  Check the union operation to see if the same InfoProvider is listed more than once.
  
  
  
  Remove Duplicate References:
  
  If you find that the same provider is included multiple times, remove the duplicate entry. Ensure that each InfoProvider is only referenced once in the union.
  
  
  
  Check for Derived Queries:
  
  If you are using derived queries or composite providers, ensure that the same InfoProvider is not being included multiple times across different layers.
  
  
  
  Validate the Query:
  
  After making changes, validate the query to ensure that it runs without errors.
