How to trigger Flow only on creation (not on Modified) of SP List Item

[RomanKorchak]

Hi All

I am creating a flow that should only be started when SharePoint list item is created but not when item is modified (Approver needs to edit some info in item during the flow). But if the item is modified it retrigger the flow.

Also is there any way to re submit the flow from itself (on some condition, for example if one approver reject the flow).

Thanks

Use the When an item is created trigger, and not the When an item is created or modified trigger.

Approval Flows have built in trees for rejections and approvals. The Build a flow that processes an approval request Microsoft Learn Module steps you through the process of creating a basic approval Flow. Also, see the Create and test an approval workflow with Power Automate documentation. 

If you could provide an expanded screenshot of your Flow and steps, and of any detailed error messages you're receiving we could likely better assist you. Also, for the best results, you may want to review How to write a good forum post.

@Brad_Groux - Thanks for your tips, I will look in to it. 

Is it possible to change the trigger on existing flow from on create and modify to on create only?

Thanks

Unfortunately, it is not possible to change the trigger of a Flow, because changing the trigger completely changes the underlying logic. You'll need to recreate the Flow with the new trigger. I usually open up the old Flow on a second browser tab so I can review and/or copy/paste the settings and steps as required.

You CAN delete the original trigger using the [...] menu and select a new trigger action. HOWEVER, when you do that, you will lose any references back to the original connection (like SharePoint list data being used in variables, conditions, or email).

Additionally, some triggers automatically include other actions like Approvals. If you add one of these triggers manually after the Flow has been created, you may have to also manually build all of the sub-actions as well.

Depending on which actions you are deleting and adding, it might be better to just create a new Flow with the correct trigger.
