• What is the cause and solution for SAP error message RSRTS_CDS208 - Parameter &1 value help: field &2 must to be a single value filter ?

  The SAP error message RSRTS_CDS208 typically occurs in the context of using the SAP BW (Business Warehouse) Query Designer or when executing queries that involve Core Data Services (CDS) views. This error indicates that a parameter in your query is expected to be a single value filter, but it has been provided with multiple values or an incorrect format.
  Cause:
  The error is caused by the following scenarios:
  
  Multiple Values Provided: The parameter specified in the query is set to accept only a single value, but the user has selected or input multiple values.
  Incorrect Filter Configuration: The filter configuration in the query or the CDS view may not be set up correctly to handle the expected input.
  Data Type Mismatch: The data type of the parameter may not match the expected type, leading to confusion in how the filter is applied.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Parameter Input:
  
  Ensure that the parameter (denoted as &1 in the error message) is being provided with a single value. If you are using a selection screen or input field, make sure that it is not allowing multiple selections.
  
  
  
  Modify Query Filters:
  
  If you are using a query in the Query Designer, check the filter settings for the parameter. Ensure that it is configured to accept only a single value. You can do this by:
  
  Opening the query in Query Designer.
  Navigating to the "Filter" section.
  Ensuring that the filter for the parameter is set to "Single Value" instead of "Multiple Values".
  
  
  
  
  
  Review CDS View Definition:
  
  If the error is related to a CDS view, review the definition of the view to ensure that the parameters are defined correctly. Check the annotations and ensure that they specify the expected behavior for filtering.
  
  
  
  Test with Different Values:
  
  Try executing the query with different single values to see if the error persists. This can help identify if the issue is with specific values or the overall configuration.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or community forums for additional insights on the specific parameter and its expected behavior.
