  The SAP error message CRM_IU_BRF117: Invalid column combination: overlapping columns typically occurs in the context of Business Rule Framework (BRF) in SAP CRM. This error indicates that there is a conflict in the column definitions used in a BRF rule or decision table, specifically that there are overlapping or conflicting columns that cannot be processed together.
  Cause:
  
  
  Overlapping Columns: The error arises when two or more columns in a decision table or rule are defined in such a way that their values overlap or conflict. For example, if you have two columns that are supposed to represent mutually exclusive conditions but are defined in a way that they can both be true at the same time.
  
  
  Incorrect Configuration: The configuration of the decision table or rule might not adhere to the expected logical structure, leading to ambiguity in how the rules should be evaluated.
  
  
  Data Model Issues: There may be issues with the underlying data model that the BRF is using, such as incorrect relationships or definitions that lead to overlapping conditions.
  
  
  Solution:
  
  
  Review Column Definitions: Check the definitions of the columns in the decision table or rule. Ensure that they are mutually exclusive and do not overlap in terms of the values they can take.
  
  
  Adjust Logic: If the columns are intended to represent different conditions, adjust the logic to ensure that they do not conflict. This may involve changing the conditions or the way they are evaluated.
  
  
  Test with Sample Data: Use sample data to test the decision table or rule to see if the error persists. This can help identify specific combinations of values that lead to the error.
  
  
  Consult Documentation: Refer to SAP documentation or help resources related to BRF and decision tables for guidance on proper configuration and best practices.
  
  
  Seek Support: If the issue persists after reviewing and adjusting the configuration, consider reaching out to SAP support or consulting with a technical expert who specializes in SAP CRM and BRF.
