• What is the cause and solution for SAP error message CLMM018 - Characteristic &: interval values are not possible ?

  The SAP error message CLMM018, which states "Characteristic &: interval values are not possible," typically occurs in the context of classification and variant configuration in SAP. This error indicates that the interval values defined for a characteristic are not valid or cannot be processed as expected.
  Cause:
  
  
  Invalid Interval Definition: The intervals defined for the characteristic may not align with the allowed values or ranges. For example, if a characteristic is defined to accept values between 1 and 10, but an interval of 5 to 3 is defined, this would trigger the error.
  
  
  Data Type Mismatch: The characteristic may have a data type that does not support interval values. For instance, if the characteristic is defined as a string or a non-numeric type, using interval values would be inappropriate.
  
  
  Missing Values: If the characteristic is expected to have certain values defined in the system and those values are missing or incorrectly configured, it can lead to this error.
  
  
  Configuration Issues: There may be issues in the configuration of the classification system or the variant configuration that lead to inconsistencies in how intervals are defined or processed.
  
  
  Solution:
  
  
  Check Characteristic Definition: Review the definition of the characteristic in the classification system. Ensure that the intervals are defined correctly and that they fall within the acceptable range.
  
  
  Validate Data Types: Ensure that the data type of the characteristic supports interval values. If necessary, change the data type to a numeric type that can handle intervals.
  
  
  Correct Interval Values: If the intervals are incorrectly defined (e.g., start value is greater than end value), correct them to ensure they are logical and valid.
  
  
  Review Configuration: Check the configuration settings in the variant configuration and classification system to ensure that they are set up correctly. This includes checking dependencies and constraints that may affect the characteristic.
  
  
  Test with Sample Data: After making changes, test the characteristic with sample data to ensure that the error does not reoccur.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on defining characteristics and intervals.
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
