Workflow using object DRAW

[ASSY, SOSTHENE]

Hi  Everybody
I'm working on the DMS workflow using the object DRAW.
Everything is fine. I've created my own approval path table.
But I got one problem.
When I'm executing my workflow it's , the same workflow is triggered twice
and 2 work items are created
Did somebody meet the problem ?
 
NB :  when I used the Generate  Event, everything is fine.
