• What is the cause and solution for SAP error message RSDD_LM006 - At least one provider is required as a union ?

  The SAP error message RSDD_LM006, which states "At least one provider is required as a union," typically occurs in the context of SAP BW (Business Warehouse) when working with InfoProviders, particularly when you are trying to create or modify a MultiProvider or a CompositeProvider.
  Cause:
  This error usually arises when you are attempting to create a MultiProvider or CompositeProvider without including any valid InfoProviders. The system expects at least one InfoProvider to be included in the union operation, and if none are specified, it triggers this error.
  Solution:
  To resolve the RSDD_LM006 error, follow these steps:
  
  
  Check the InfoProvider Configuration:
  
  Open the MultiProvider or CompositeProvider in the SAP BW modeling tools.
  Ensure that you have added at least one valid InfoProvider (e.g., InfoCube, DataStore Object, or another MultiProvider) to the union.
  
  
  
  Add InfoProviders:
  
  If no InfoProviders are present, click on the option to add InfoProviders.
  Select the appropriate InfoProviders that you want to include in the union.
  
  
  
  Validate the Model:
  
  After adding the required InfoProviders, validate the model to ensure there are no other issues.
  Save your changes.
  
  
  
  Check for Filters or Conditions:
  
  If you have applied filters or conditions that might exclude all InfoProviders, review and adjust them accordingly.
  
  
  
  Re-activate the Provider:
  
  If you have made changes, you may need to re-activate the MultiProvider or CompositeProvider to ensure that the changes take effect.
  
  
  
  Related Information:
