Restart chain on failed step

What is it?​

The Restart On Step option resumes a failed SAP BW process chain at the failure point instead of running the entire chain again. Use it when earlier steps have already completed successfully and re-running them would be expensive or time-consuming.

How to restart at the failed step​

To resume a failed process chain at the failed step, complete the following steps:

  1. Right-click the failed SAP BW job. The context menu displays.
  2. Select Restart On Step. A pop-up displays the Chain ID of the previously run BW chain that failed.
  3. Select the Chain ID.
  4. Select the Restart On Step button. The chain restarts at the point of failure.
  5. Wait for the usual job status updates until the job finishes and the JobLog and Spool List are retrieved.
note

To re-run the chain from the beginning instead, select Restart rather than Restart On Step when you right-click.

FAQs​

When should I use Restart On Step instead of Restart? Use Restart On Step when earlier steps in the chain already completed successfully and you only want to re-run from the failure point.

Where does the Chain ID come from? The pop-up displays the Chain ID of the previously run BW chain that failed. Selecting that Chain ID and selecting Restart On Step resumes the chain at the point of failure.
