Flow Trigger

Hello Community,

 

I have a Flow "A" and i want to build a Flow "B"
Flow A should start Flow B

A:

- Flow Management
- Turn on Flow
- Start Flow B

 

Now, i want to build Flow B

B:

First of all i need a trigger?
But this is exactly my problem. Which one is right?
I dont want Sharepoint or Outlook or PowerApps as trigger.
I want another Flow as trigger but i dont find this Option!?

What can i do?

I hope you can help me.

Thank you!!!
Vasili

Re: Flow Trigger

You can trigger Flow B directly from Flow A using an HTTP request action.  This will require premium licensing but it works. Take a look at this article

Re: Flow Trigger

Hello Pstork1,

first of all thank you very much for the fast response.

I just read the workaround from the o365tech8 website and yeah what should i say.... it looks complex.
I dont unterstand why it should be so complex.....
To start a flow as trigger from another flow is an obvious scenario for me...

I am a little disappointed but i will try the solution.
I will get in touch later.

Thank you.

Re: Flow Trigger

Hi there,

 

An out of the box workaround (albeit, with some limitations) could work if the context is SharePoint.  

 

Have Flow A set a yes/no column on a SharePoint list item, which acts as the Flag for Flow B.

 

Have Flow B run on a schedule to Get Items from that list where those items have been flagged (use a filter) and then execute.

 

At the end of Flow B, update the SP list item to NO to unflag the item.

 

Good luck!

Ashley

Re: Flow Trigger

Hello Ashley,

thank you for the answer.
This is a good point... i already think about it.
I work with powerapps and i try to build a business solution...
The workflow is complex and i have roughly 20 flows....
If i do this with sharepoint list items it could be very fast very confusing...
especially to monitoring later.

 

I will think about the Solution with Sharepoint and HTTP Reguest again and i will decide.

I hope microsoft will build this function in the future.

 

Thank you.

Re: Flow Trigger

I understand what you're trying to accomplish, but I'm curious as to why you would want to do this. If Flow A always triggers Flow B, why do you want two separate flows? Why not just make them a single flow?

 

Regardless, a simple solution would be to end Flow A by creating something any place where you can store a value or object: a queue, a file, a SQL table, etc. The trigger for Flow B would be to watch for that object/value to be created. Then Flow B would end by removing that created trigger value. For example, Flow A ends by creating an empty text file in a OneDrive folder. The trigger for Flow B is watching for a file to be created in the OneDrive folder. Then, when Flow B ends, it deletes that created file.

Thank you for the answer barret,

This is exactly what i dont want to do. As i say i have around 20 Flows and Flow A dont triggers always flow B.

Yes, i think this will be my way to solve the problem.

Ich will try this 🙂
