• What is the cause and solution for SAP error message RSDD094 - Variable &1 must return a unique value ?

  The SAP error message RSDD094, which states "Variable &1 must return a unique value," typically occurs in the context of SAP BW (Business Warehouse) when a query is executed that involves a variable that is expected to return a single value, but instead returns multiple values or no values at all. This can happen in various scenarios, such as when using selection variables in queries or when filtering data.
  Cause:
  
  Multiple Values Returned: The variable defined in the query is set up to return a single value, but the underlying data or selection criteria are returning multiple values.
  No Value Returned: The variable might not have any values available based on the current selection criteria, leading to ambiguity.
  Incorrect Variable Settings: The variable might be incorrectly configured in the query definition, such as not being set to allow for single value selection.
  Data Issues: There may be issues with the data itself, such as duplicates or incorrect data entries that lead to multiple valid selections.
  
  Solution:
  
  
  Check Variable Configuration:
  
  Go to the query definition in the Query Designer and check the settings of the variable. Ensure that it is set to return a single value.
  If the variable is meant to allow multiple selections, adjust the settings accordingly.
  
  
  
  Review Data:
  
  Analyze the data in the InfoProvider to ensure that the variable is indeed supposed to return a unique value. Check for duplicates or unexpected entries that might cause multiple values to be returned.
  
  
  
  Modify Query Logic:
  
  If the variable is intended to filter data, consider modifying the query logic to ensure that it can handle cases where multiple values might be returned. This could involve using additional filters or conditions.
  
  
  
  Test the Variable:
  
  Test the variable independently to see what values it returns. This can help identify if the issue lies with the variable itself or with the query.
  
  
  
  Use Default Values:
  
  If appropriate, set a default value for the variable that can be used when no unique value is available.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or support resources for specific guidance on handling variables in queries.
