Hi, I’ve a workflow that runs well when I run it manually, but that doesn’t do anything when running it via batch.  
This is the error that I got in the log :  
“java.io.IOException: The process cannot access the file because another process has locked a portion of the file”

Could someone help please?

Many thanks, Amélie
