Workflow should execute when EPMDocument Checkin not when EPMDocument Save and Uploaded

Hello ,

I created workflow, which need to execute when EPMDocument checked in from PROE. I set Workflow in INWORK state of EPMDocument lifecycle.

I added synchronize robot on CHECKIN event of EPMDocument in workflow immediately after START  , I added below code in synchronize robot that if EPMDocument path doesn't contain EPMDocument creator name then only proceed workflow .

However the workflow executes when I click SAVE & UPLOAD  the Drawing in PROE, rather It should be executed when I click CHECK IN the Drawing.

So When I click CHECKIN , workflow doesn't execute Synchronize robot because it already executed  ...

Does anybody have idea about How I can solve this issue?

primaryBusinessObject is EPMDocument

if ( primaryBusinessObject != null ) {

            String stringCreator = ( (wt.epm.EPMDocument) primaryBusinessObject ).getCreatorName() ;

            String stringForlderPath = ( (wt.epm.EPMDocument) primaryBusinessObject ).getFolderPath() ;

                if( ! stringForlderPath.contains( stringCreator )  ) {

                           result = "ok";

                }

}
