• What is the cause and solution for SAP error message CNV_20310_CHECK046 - All mapping values are permitted ?

  The SAP error message CNV_20310_CHECK046 with the description "All mapping values are permitted" typically occurs during data migration or conversion processes, particularly when using SAP's data migration tools like the SAP S/4HANA Migration Cockpit or the SAP Data Services.
  Cause:
  This error generally indicates that there is an issue with the mapping of values in the data migration process. Specifically, it suggests that the system has detected that all possible values for a certain field are allowed, but the mapping configuration does not align with the expected values or constraints. This can happen due to:
  
  Incorrect Mapping Configuration: The mapping rules defined for the data conversion may not be set up correctly, leading to a situation where the system cannot determine which values are valid.
  Missing Value Restrictions: The target field may have specific value restrictions that are not being adhered to in the mapping.
  Data Quality Issues: The source data may contain unexpected or invalid values that do not match the target field's requirements.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Mapping Configuration:
  
  Check the mapping rules defined in the migration tool. Ensure that the source values are correctly mapped to the target values.
  Make sure that the mapping includes all necessary value transformations and that there are no missing mappings.
  
  
  
  Validate Source Data:
  
  Inspect the source data for any anomalies or unexpected values that may not conform to the expected format or range.
  Cleanse the data if necessary to ensure it meets the target field's requirements.
  
  
  
  Check Target Field Constraints:
  
  Review the target field's data type and constraints in the target system. Ensure that the mapping aligns with these constraints.
  If the target field has specific allowed values, ensure that the mapping only includes those values.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the specific migration tool you are using. There may be additional guidelines or best practices for setting up mappings.
  
  
  
  Testing:
  
  After making adjustments, run a test migration with a small subset of data to verify that the error has been resolved.
