DELMIA Service Process Structure - Automation of product flow through EKL

Hello Delmia Community,

I'm looking for a way to make product flow between operations OR Workplan through a EKL.

I tried the wiki before posting this question. 

I'm using the DELMIA Services objects of 3Dexperience. There is a small different between classes and names. 

Can you help me to find a solution please ?
