RSM079
- Cannot obtain lock for DTP load switch; termination; DTA &;DS &;LS & ?The SAP error message RSM079 indicates that there is an issue with obtaining a lock for the Data Transfer Process (DTP) load switch. This typically occurs when multiple processes are trying to access the same DTP simultaneously, leading to a conflict. Here’s a breakdown of the cause, potential solutions, and related information:
Cause: Concurrent Execution: The most common cause is that multiple DTP processes are trying to run at the same time, which leads to a locking conflict. Long-Running Processes: If a DTP is taking a long time to complete, it may hold the lock longer than expected, preventing other processes from obtaining the lock. System Performance Issues: High system load or performance issues can also lead to delays in lock acquisition.
Configuration Issues: Incorrect configuration of the DTP or the underlying data sources can lead to locking issues. Solutions: Check Running Processes: Use transaction codes like SM37 to check for any running or stuck DTP processes.
