How to use action, subflow and flow in one go?

[BijoyDeb]

Hi, i have a scenario which i want to do by flow designer, but not sure how to do

First we should have one action within which there will be script step to create incident and should give output as that created incident number.

Then that action should be called from subflow so that its output will be the same number

And finally need to call that subflow from any flow so that we just will get that incident number when we test that flow. Now im not getting whether we can show log or output when flow is tested 

I havent worked on flow designer, please let me know how to do this briefly if possible

Thanks

if you haven't worked on Flow Designer then how did you decide on the design in advance?
The way I deal with flow designer of any complexity is to write out very simple instructions in english for every step.

But your statements skip right to the logic:
- First we should have one action within which there will be script step to create incident    WHY?
- Then that action should be called from subflow so that its output will be the same number    WHY?

Don't start at how you want the flow to be.  
Start with what you want to happen, expressed in plain language.

@Uncle Rob , Thanks for your suggestion.

Actually, this is one scenario which i thought i could start with basics of flow designer that i got to know from developer community only.

Why not start with something WAY simpler?
