• What is the cause and solution for SAP error message TN_PROCESS148 - Stack XML also contains add-on uninstallations ?

  The SAP error message "TN_PROCESS148 Stack XML also contains add-on uninstallations" typically occurs during the transport process in SAP, particularly when dealing with the transport of software components or add-ons. This error indicates that the transport request includes uninstallations of add-ons, which is not allowed in certain contexts or configurations.
  Cause:
  
  Transport Request Configuration: The transport request may have been incorrectly configured to include both installations and uninstallations of add-ons. SAP does not allow the transport of uninstallations in certain scenarios.
  Add-on Management: The system may have inconsistencies in the add-on management, where the system is trying to uninstall an add-on that is still in use or has dependencies.
  Stack XML Issues: The Stack XML file generated during the transport process may contain references to add-on uninstallations, which can lead to this error.
  
  Solution:
  
  Review Transport Request: Check the transport request to ensure that it does not include any uninstallations of add-ons. If it does, you may need to create a separate transport request for the uninstallations or remove them from the current request.
  Adjust Stack XML: If you have access to the Stack XML, review it to identify any references to add-on uninstallations. You may need to manually edit or regenerate the Stack XML to exclude these references.
  Check Add-on Status: Verify the status of the add-ons in your system. Ensure that any add-ons you are trying to uninstall are not currently in use or do not have dependencies that prevent their uninstallation.
  Consult SAP Notes: Look for relevant SAP Notes that may address this specific error. SAP frequently updates its knowledge base with solutions for common issues.
