• What is the cause and solution for SAP error message RSDD_LM004 - Provider '&1' is used as a join more than once ?

  The SAP error message RSDD_LM004 indicates that a particular InfoProvider (denoted as '&1') is being used as a join more than once in a query or a data model. This situation typically arises in the context of SAP BW (Business Warehouse) or SAP HANA when defining queries or data models that involve multiple joins.
  Cause:
  The error occurs because the same InfoProvider is being referenced multiple times in a way that is not allowed. This can happen in scenarios such as:
  
  Using the same InfoProvider in multiple joins within a single query.
  Incorrectly defining relationships in a CompositeProvider or MultiProvider.
  Having a complex data model where the same InfoProvider is inadvertently included multiple times.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Query or Data Model:
  
  Check the query definition or the data model where the error is occurring.
  Identify where the same InfoProvider is being used multiple times.
  
  
  
  Modify Joins:
  
  If the same InfoProvider is being joined multiple times, consider whether you can consolidate the joins or redesign the query to avoid redundancy.
  You may need to create a new InfoProvider or use a different approach to achieve the desired data output.
  
  
  
  Use Aliases:
  
  If you need to join the same InfoProvider multiple times for different purposes, consider using aliases (if supported) to differentiate between the instances.
  
  
  
  Check CompositeProviders:
  
  If you are using CompositeProviders, ensure that the InfoProvider is not included more than once in the definition.
  Review the underlying data sources and their relationships.
  
  
  
  Test Changes:
  
  After making adjustments, test the query or data model to ensure that the error is resolved and that the output is as expected.
