Hello community,
I have a question about correct process setup for EFS. 

There is a very simple MBOM (drill assembly) and simple process flow – page 2 and 3 in attached ppt.

I've tried several process flow configuations but always was some problem(s) with factory flow (with two workstations WS1, WS2). 

In attached ppt on pages 4 and 5 is first process setup – just "loading" activities.

Problem with „loading activities“ is, that there is no product for „out-flow activity“ from WS1 and no „in-flow activity“ in WS2. 

So I tried several other process flow wariants with „Header Operation“ and/or „General Operation“ but still with several problems – see pages 7 and 8. (Update 25.11.2022)

What I want to reach is procedure for EFS – see page 6. Could you please give me description of right process flow setup for „Synchronization“ with EFS. Hand writed simple description is ok.
