• What is the cause and solution for SAP error message RSDD_LM002 - CompositeProvider field '&1' is not unique ?

  The SAP error message RSDD_LM002, which states that "CompositeProvider field '&1' is not unique," typically occurs in the context of SAP BW (Business Warehouse) when working with CompositeProviders. This error indicates that there is a field in the CompositeProvider that is not uniquely defined, which can lead to ambiguity in data retrieval and reporting.
  Cause:
  
  
  Non-Unique Field Definitions: The field specified in the error message is likely defined in multiple underlying InfoProviders (e.g., InfoCubes, DataStore Objects) that are part of the CompositeProvider. This can happen if the same field name exists in more than one source without proper differentiation.
  
  
  Incorrect Mapping: The mapping of fields from the underlying providers to the CompositeProvider may not be set up correctly, leading to conflicts.
  
  
  Data Model Design Issues: The design of the data model may not have taken into account the uniqueness of fields when combining multiple sources.
  
  
  Solution:
  
  
  Check Field Definitions: Review the field definitions in the underlying InfoProviders. Ensure that the field causing the error is unique across all the sources included in the CompositeProvider.
  
  
  Rename Fields: If the same field name exists in multiple sources, consider renaming the fields in the underlying InfoProviders or using aliases in the CompositeProvider to differentiate them.
  
  
  Adjust CompositeProvider Settings: 
  
  Go to the CompositeProvider in the SAP BW modeling tools.
  Check the field mappings and ensure that each field is uniquely defined.
  If necessary, remove or adjust the conflicting fields.
  
  
  
  Use Key Fields: Ensure that the key fields in the CompositeProvider are properly defined and that they uniquely identify records.
  
  
  Testing: After making changes, test the CompositeProvider to ensure that the error is resolved and that data retrieval works as expected.
