I believe you'll have to be more specific... What does the log say? Are there any features entering the WorkspaceRunner?

Sorry david_r. The child WorkSpaceRunner is expected to load data from database X to database Y. The step previous to the child WorkSpaceRunner is an SQL Executor running a Stored Procedure to empty the database Y. On completion, the SQL Executor feeds Result value 1 to kickstart the child WorkspaceRunner.

But, somehow the run is not initiated and the Parent Workspace completes.

What does the log say? Anything mentioning the WorkspaceRunner?

I have attached image of the log file search results regarding the WorkspaceRunner. I couldn't make much sense of it. Hopefully, you can enlighten me.

I'm sorry, but there's too little context for me to get anything helpful out of this. If you cannot post more detailed information for confidentiality reasons, consider going straight to your FME reseller/partner for support, rather than using these public forums.

@ravibansal​  Sometimes this occurs if the parameters in the parent WorkspaceRunner are not passing as expected to the Child workspace. In your log file search out the lines:

INFORM|WorkspaceRunner

These will show you the parameters that were passed. There should also be a log file associated with the child workspace and this might also give you the clues you need to understand why the job failed.
