• What is the cause and solution for SAP error message USMD_CMM020 - Value &1 is not allowed for parameter &2 ?

  The SAP error message USMD_CMM020 indicates that a specific value is not allowed for a given parameter in the context of the SAP Master Data Governance (MDG) application. This error typically arises when there is an attempt to use a value that does not meet the predefined criteria or constraints set within the system for that parameter.
  Cause:
  
  
  Invalid Value: The value being assigned to the parameter does not conform to the allowed values defined in the system. This could be due to:
  
  The value being outside of a defined range.
  The value not being part of a predefined list of acceptable values.
  The value being in the wrong format (e.g., a string instead of a number).
  
  
  
  Configuration Issues: There may be configuration settings in the MDG that restrict certain values for specific parameters.
  
  
  Data Model Constraints: The data model associated with the master data might have constraints that are not being met by the input value.

  Modifying the data model.
