Going back to the parent flow

[Ramesh Krishnamoorthy]

I have a child flow (some kind of reusable flow)  that I want to use in multiple parent flows. When the user enters the child flow, at some point I want to take the user back to the parent floe they came from. Since they can enter the child flow from any of the parent flows, how can I take the user back to the correct parent flow? "Enter a Flow" action doesn't allow any function or variable name. Is this possible?

[Rudi Giesler]

If the child flow just exits, it will go back to the parent flow. So you just need to attach something to the red dots under the "Enter a Flow" action in the parent flow.

Regards,

Rudi.

Hi Rudi,

Thanks for the quick response. 

Need some clarification: How will the child flow exit? 

If the last node in the child flow is expecting a response from the user and saves to a result as below, result A is supposed to go back to the parent menu where it branched off. Is that possible? How? Thanls

Are you trying to build your own flow engine or run RapidPro? RapidPro has supported subflows and accessing child results in parent flows for years.

I am not denying that in anyway Rowan. I am just not understanding how. If you can help, it will be great. Thx

[Rowan Seymour]

I'm just trying to understand what you are asking - how to use RapidPro to create subflows or how to implement subflows in a different engine using the RapidPro flow editor. If it's the latter then you're probably best taking a good look at the code behind the RapidPro engine at https://github.com/nyaruka/goflow.

I am NOT creating a new flow engine. I am just trying to use RapidPro as is. Just wanted to know how to get back to the parent from a child flow cleanly to the place where the child flow branched off. I am trying this for the first time so just needed guidance. Thx

[Ramesh Krishnamoorthy]

Just to clarify, in the screen shot I have shared above, if the user picks option A,  I just want to save it and exit to the parent flow. How to do that? I don't want the child flow to expire, but rather I want to go to the parent flow as soon as the user picks 'A'. Is that possible?

[Rowan Seymour]

As soon as the contact sends A, you'll go to the connected Send Message, and then the child flow will end. Then the parent flow will resume from the Enter Flow action where it initiated the child flow.

Ok, got it. Will give it a try with multiple parent flows and see if I am able to get back to the branch off point in each parent. Thanks for your patience and assistance.
