• What is the cause and solution for SAP error message MEREP_01012 - MSG_HDR GUID does not match device header GUID ?

  The SAP error message MEREP_01012 with the description "MSG_HDR GUID does not match device header GUID" typically occurs in the context of SAP Mobile Platform or SAP Mobile Services when there is a mismatch between the GUID (Globally Unique Identifier) of the message header and the device header. This can happen during communication between the mobile application and the backend system.
  Causes:
  
  Inconsistent GUIDs: The GUID in the message header does not match the GUID in the device header, which can occur if the device has been re-registered or if there are issues with the session management.
  Network Issues: Intermittent network issues can lead to corrupted messages or incomplete data being sent.
  Version Mismatch: If there are different versions of the mobile application or backend services, it may lead to incompatibility in the GUIDs.

  Re-register the Device: If the device has been re-registered, ensure that the application is using the correct GUIDs. You may need to clear the application data or reinstall the app.
