• What is the cause and solution for SAP error message RSDD_LM035 - Provider '&1' (alias &2) is already being used as a join ?

  The SAP error message RSDD_LM035 indicates that a particular data provider (such as an InfoProvider or a MultiProvider) is already being used as a join 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 query that involves multiple data sources.
  Cause:
  The error is triggered when:
  
  You attempt to use the same InfoProvider (or its alias) in multiple joins within a single query or data model.
  The system does not allow the same provider to be joined multiple times in a single context to avoid ambiguity and ensure data integrity.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Query Design: Review the query or data model where the error occurs. Look for instances where the same InfoProvider is being used in multiple joins. 
  
  
  Modify Joins: If you find that the same provider is being used multiple times, consider:
  
  Removing duplicate joins.
  Using different InfoProviders if possible.
  Restructuring the query to avoid the need for multiple joins with the same provider.
  
  
  
  Use Aliases: If you need to join the same InfoProvider for different purposes, consider creating an alias for the InfoProvider. This allows you to reference the same underlying data source without causing conflicts.
  
  
  Check for Dependencies: Ensure that there are no dependencies or other queries that might be using the same provider in a conflicting manner.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on how to structure queries and joins effectively.
  
  
  Testing: After making changes, test the query to ensure that it runs without errors and returns the expected results.
  
  
  Related Information:
  
  SAP BW Query Designer: Familiarize yourself with the Query Designer tool, as it provides a visual interface for managing InfoProviders and joins.
  Performance Considerations: Be mindful of performance implications when restructuring queries, as complex joins can impact query performance.
