  • What is the cause and solution for SAP error message U1826 - Writing into cluster is not possible due to another parallel TR execution ?
    The SAP error message U1826 indicates that there is an issue with writing data into a cluster because another transport request (TR) is currently executing in parallel. This situation typically arises in environments where multiple transport requests are being processed simultaneously, and the system is trying to access the same cluster data.
    
    Cause: Parallel Execution: The error occurs when two or more transport requests are trying to write to the same cluster at the same time.
