• What is the cause and solution for SAP error message DMC_TRANSPORT000 - Disallowed value in CASE loop in &1 ?

  The SAP error message DMC_TRANSPORT000 with the description "Disallowed value in CASE loop in &1" typically occurs in the context of Data Migration Cockpit (DMC) or during data transport processes. This error indicates that there is an issue with the values being processed in a CASE statement within the data transformation logic.
  Cause:
  
  
  Invalid Value: The error is often triggered when the data being processed contains a value that is not allowed or expected in a CASE statement. This could be due to:
  
  Incorrect data mapping.
  Data that does not conform to the expected format or range.
  Missing values that are required for the CASE logic to function correctly.
  
  
  
  Configuration Issues: There may be issues with the configuration of the data migration or transport process, such as incorrect settings in the transformation rules.
  
  
  Data Quality Issues: The source data may contain inconsistencies or errors that lead to unexpected values being encountered during processing.
  
  
  Solution:
  
  
  Review the Data: Check the source data for any invalid or unexpected values that may be causing the error. Ensure that all values conform to the expected formats and ranges.
  
  
  Check Transformation Logic: Review the transformation rules and CASE statements defined in the DMC. Ensure that all possible values are accounted for in the CASE logic. If there are values that are not handled, consider adding additional branches to the CASE statement to manage them appropriately.
  
  
  Data Mapping: Ensure that the data mapping is correctly defined and that all necessary mappings are in place. If there are any missing mappings, add them to resolve the issue.
  
  
  Error Handling: Implement error handling in the transformation logic to manage unexpected values gracefully. This could involve logging the errors or providing default values for unhandled cases.
  
  
  Testing: After making changes, test the data migration or transport process with a subset of data to ensure that the issue is resolved before running it on the full dataset.
