• What is the cause and solution for SAP error message RSDD_LM034 - Provider '&1' (alias &2) is already being used as a union ?

  The SAP error message RSDD_LM034 indicates that a particular provider (in this case, a DataSource or InfoProvider) is already being used as part of a union in a query or a data model. This typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when you are trying to create or modify a union of multiple InfoProviders, and the specified provider is already included in another union.
  Cause:
  
  Duplicate Usage: The provider you are trying to add to a union is already part of another union. In SAP BW, a union can only include each InfoProvider once.
  Modeling Error: There may be a misunderstanding in the data model where the same InfoProvider is being referenced multiple times in different unions.
  Query Design: If you are designing a query that involves multiple unions, you might inadvertently be trying to include the same InfoProvider in more than one union.
  
  Solution:
  
  Check Existing Unions: Review the existing unions in your data model to see where the provider is already being used. You can do this by navigating to the relevant InfoProvider or union in the SAP BW modeling tools.
  Modify the Union: If the provider is already part of a union, you will need to decide whether to remove it from the existing union or to use a different provider in your new union.
  Create a New Union: If you need to use the same provider in a different context, consider creating a new union that does not include the conflicting provider.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on how to properly structure unions and InfoProviders in your specific version of SAP BW.
