Can I recursively call a flow or subflow?

[jordimsant]

I was trying to develop a flow and this question came to my mind. Is it possible to create loops using a flow? Can I recursively call a flow to achieve this goal? I have tried many ways and I have not found how to do it.

Not certain why you would want to recurve flow.

It is possible to create a recursive flow as is written in the following page but there is usually a better way to define a flow without recursion.

You maybe given a record and need to find all associated sub records / flows to it and any children.

Cannot do in a single call as there is now way of getting the values until you know the next level

Your RITM calls a flow, so the first record is the RITM sys_id
You now search on the sys_id of the sys_flow_context to get all sub flows from the first flow.
Repeat until you have no further flow contexts

Likewise for RITM/Task or anykind.  Seen many where the flow will do some work and a customer has allowed their itil users to add another type of record, and the parent value is not the calling REQ/RITM, but maybe a sc_task, vtb_task and so on.

Hello @jordimsant,

If you are talking about looping, you can always use Do the following flow logic to create a loop that repeatedly applies one or more actions. This flow logic requires a condition specifying when to stop the loop.

You can go through product documentation!

Please hit the thumbs up if this info helps!
Thanks!

Maybe, but too many loop steps or overall steps will stop a flow

By calling a subflow recursively you eliminate that

For the example above, on the sys_flow_context, no idea how many flows or subflows are called, so where does you loop end and how many steps.

You can call a sub flow and run 100 steps with no worries, can't do that as an all in one flow
