• What is the cause and solution for SAP error message UCU1120 - Specify a single value for independent characteristic &1 ?

  The SAP error message UCU1120, which states "Specify a single value for independent characteristic &1," typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when working with queries or data models that involve characteristics in a query or data selection.
  Cause:
  This error arises when a query or selection is expecting a single value for a characteristic, but multiple values or no values are provided. Independent characteristics are those that are not dependent on other characteristics in the context of the query. The system requires a specific value to filter the data correctly, and when it receives multiple values or none, it cannot process the request.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Query/Selection Criteria:
  
  Review the query or selection criteria where the error is occurring. Ensure that for the independent characteristic mentioned in the error message, you are providing a single value.
  
  
  
  Modify the Input:
  
  If you are using a selection screen or input parameters, ensure that you are selecting only one value for the characteristic in question. If you are using a variable, check its settings to ensure it is configured to accept only a single value.
  
  
  
  Review the Data Model:
  
  If you are working with a data model or InfoProvider, ensure that the characteristic is defined correctly and that it is set up to accept single values as expected.
  
  
  
  Check for Default Values:
  
  Sometimes, default values may be set in the query or selection. Ensure that these defaults do not conflict with the requirement for a single value.
  
  
  
  Test with Different Values:
  
  If applicable, try running the query with different single values for the characteristic to see if the error persists.
  
  
  
  Consult Documentation:
