• What is the cause and solution for SAP error message CNV_DMC_MC_EXCEPTION106 - Field based rules must have exactly one export parameter ?

  The SAP error message CNV_DMC_MC_EXCEPTION106 indicates that there is an issue with field-based rules in the Data Migration Cockpit (DMC) where the rules are expected to have exactly one export parameter. This error typically arises during the execution of data migration tasks when the defined rules do not meet the expected criteria.
  Cause:
  The error is caused by one of the following reasons:
  
  Incorrect Rule Definition: The field-based rule defined in the DMC has either no export parameters or more than one export parameter. The system requires exactly one export parameter for the rule to function correctly.
  Configuration Issues: There may be a misconfiguration in the data migration project or the rules that have been set up.
  Data Model Issues: The data model being used may not align with the expected structure for the rules defined.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Field-Based Rules:
  
  Go to the DMC and check the field-based rules that you have defined.
  Ensure that each rule has exactly one export parameter. If there are none or more than one, modify the rule accordingly.
  
  
  
  Modify the Rule:
  
  If you find that a rule has no export parameters, add the necessary export parameter.
  If there are multiple export parameters, remove the excess ones until only one remains.
  
  
  
  Test the Changes:
  
  After making the necessary adjustments, re-run the data migration task to see if the error persists.
  
  
  
  Check Documentation:
  
  Refer to the SAP documentation for the Data Migration Cockpit to ensure that you are following the correct procedures for defining field-based rules.
  
  
  
  Consult SAP Support:
