• What is the cause and solution for SAP error message RSDD_LM001 - CompositeProvider field '&1' is not linked ?

  The SAP error message RSDD_LM001, which states that the CompositeProvider field '&1' is not linked, typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when working with CompositeProviders. This error indicates that a field in the CompositeProvider is not properly linked to the underlying data sources or InfoProviders.
  Cause:
  
  Unlinked Field: The field specified in the error message is not linked to any of the underlying data sources in the CompositeProvider. This can happen if the field was added to the CompositeProvider but not mapped to a corresponding field in the source InfoProviders.
  Incorrect Mapping: There may be an issue with the mapping of fields between the CompositeProvider and the underlying InfoProviders, such as a typo or a mismatch in data types.
  Changes in Source: If there have been changes in the structure of the underlying InfoProviders (e.g., fields added or removed), the CompositeProvider may not reflect these changes correctly.
  
  Solution:
  
  
  Check Field Mapping:
  
  Open the CompositeProvider in the SAP BW Modeling Tools.
  Verify that the field mentioned in the error message is correctly mapped to a field in one of the underlying InfoProviders.
  If the field is not linked, you will need to create a mapping for it.
  
  
  
  Update CompositeProvider:
  
  If the underlying InfoProviders have changed, you may need to refresh or update the CompositeProvider to reflect these changes.
  Ensure that all necessary fields are included in the CompositeProvider and are correctly linked.
  
  
  
  Revalidate the CompositeProvider:
  
  After making changes, revalidate the CompositeProvider to check for any other potential issues.
  You can do this by right-clicking on the CompositeProvider and selecting the option to validate.
  
  
  
  Check for Data Source Changes:
  
  If there have been recent changes to the data sources, ensure that the CompositeProvider is updated accordingly.
  This may involve re-importing the data sources or adjusting the CompositeProvider configuration.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for additional guidance on CompositeProviders and field mapping.
