What causes this issue?

The previous run of the current subchain, &V3&, is not yet complete.
This leads to communication errors with the metachain called, &V4&.

System Response

The current run of the metachain is cancelled.

How to fix this error?

End the previous run of the subchain, or wait until the run is
complete.
It does not matter whether the run was successfully completed or not.

• What is the cause and solution for SAP error message RSPC090 - Previous run &1 not yet complete (status &2), termination ?

  The SAP error message RSPC090 indicates that a previous run of a process chain has not yet completed, and therefore, the current execution cannot proceed. This error typically occurs in the context of process chains in SAP BW (Business Warehouse) or SAP BW/4HANA.
  Cause:
  
  Ongoing Execution: The most common cause is that a previous instance of the process chain is still running. This could be due to long-running data loads, transformations, or other processes that have not yet finished.
  Stuck Process: Sometimes, a process may get stuck due to various reasons, such as resource contention, deadlocks, or system performance issues.
  Incorrect Configuration: There may be issues with the configuration of the process chain that prevent it from completing successfully.
  
  Solution:
  
  
  Check Running Processes:
  
  Go to transaction code RSPC (Process Chain Maintenance).
  Check the status of the process chain in question. If it shows as "Running," you will need to wait for it to complete.
  You can also check the Process Overview to see if there are any other processes that are currently running.
  
  
  
  Terminate Stuck Processes:
  
  If you determine that a process is stuck, you can terminate it. In the process chain maintenance screen, select the running process and choose the option to terminate it.
  Be cautious when terminating processes, as this may lead to data inconsistencies if not handled properly.
  
  
  
  Review Logs:
  
  Check the logs for the previous run to identify any errors or warnings that may have caused it to hang. This can provide insights into what went wrong and how to prevent it in the future.
  
  
  
  Adjust Scheduling:
  
  If the process chain is frequently running into this issue, consider adjusting the scheduling of the process chains to avoid overlaps or resource contention.
  
  
  
  System Performance:
  
  Monitor system performance and resource usage. If the system is under heavy load, it may be beneficial to optimize performance or schedule heavy processes during off-peak hours.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific process chain or error message for additional troubleshooting steps or known issues.

  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to process chains or the RSPC090 error.
  
  
  Performance Tuning: Consider performance tuning for data loads and transformations to minimize the chances of processes running longer than expected.
  
  
  By following these steps, you should be able to resolve the RSPC090 error and ensure that your process chains run smoothly.
