  • What is the cause and solution for SAP error message RSPM105 - Locking of process &1 was refused by external tool (e.g. DTP) ?
    The SAP error message RSPM105 indicates that the locking of a process (such as a Data Transfer Process, or DTP) was refused by an external tool. This typically occurs in the context of data extraction, transformation, and loading (ETL) processes within SAP BW (Business Warehouse) or SAP BW/4HANA environments.
    
    Cause: External Tool Interference: The error often arises when an external tool (like a third-party ETL tool or another SAP process) is trying to access the same data or process that is already locked by another operation. Process Conflicts: If multiple processes are trying to run simultaneously and access the same resources, it can lead to locking issues.
    Configuration Issues: Incorrect configuration of the DTP or the data source can also lead to locking problems. Long-Running Processes: If a process is taking too long to complete, it may hold onto locks longer than expected, causing subsequent processes to fail.
    Solution: Check Running Processes: Use transaction codes like SM37
