  The SAP error message SRT_CHANGE_MGMT012 indicates that there is an issue with applying incompatible data type (DT) changes to a simplified configuration in your SAP system. This typically occurs in the context of SAP Process Orchestration (PO) or SAP Cloud Platform Integration (CPI) when there are changes in the data types of the messages or interfaces that are not compatible with the existing configuration.
  Cause:
  
  Incompatible Data Type Changes: The error usually arises when there are changes made to the data types of the messages or interfaces that are not backward compatible. For example, changing a field from a string to an integer or altering the structure of a message type.
  Version Mismatch: If there are multiple versions of the same interface or message type, and the new version has incompatible changes, the system will not be able to apply these changes to the existing configuration.
  Configuration Issues: The simplified configuration may have dependencies on specific data types that are no longer valid due to the changes made.
  
  Solution:
  
  Review Changes: Check the changes made to the data types or message structures. Ensure that any changes are backward compatible or that the existing configurations are updated accordingly.
  Update Configuration: If the changes are necessary, you may need to update the existing configurations to align with the new data types. This may involve modifying mappings, interfaces, or service definitions.
  Rollback Changes: If the changes are not critical, consider rolling back to the previous version of the data type or interface that was working correctly.
  Testing: After making the necessary adjustments, thoroughly test the integration scenarios to ensure that the changes do not introduce new issues.
  Consult Documentation: Refer to SAP documentation or release notes for any specific guidelines regarding changes in data types and their impact on configurations.
