• What is the cause and solution for SAP error message SIC_NORM_CONFIG031 - Class &1 assigned to more than one basic rule type ?

  The SAP error message SIC_NORM_CONFIG031 indicates that a class (specified by &1) has been assigned to more than one basic rule type in the context of normalization configuration. This typically occurs in the SAP system when setting up normalization rules for data quality management, particularly in the context of master data governance or data cleansing processes.
  Cause:
  The error arises when:
  
  A class is defined in the normalization configuration and is mistakenly linked to multiple basic rule types. Each class should only be associated with one basic rule type to maintain clarity and avoid conflicts in data processing.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify the Class: Determine which class is causing the issue by checking the error message details where &1 is replaced with the actual class name.
  
  
  Review Normalization Configuration:
  
  Go to the normalization configuration settings in your SAP system.
  Check the assignments of the class in question and see which basic rule types it is linked to.
  
  
  
  Correct the Assignments:
  
  Decide which basic rule type the class should be associated with based on your data governance strategy.
  Remove the class from the additional basic rule types it is incorrectly assigned to.
  
  
  
  Test the Configuration: After making the necessary changes, test the normalization process to ensure that the error no longer occurs and that the data processing works as expected.
  
  
  Documentation: Document the changes made to the configuration for future reference and to help prevent similar issues.
