Trigger condition syntax

Posted on by danbert1973

I'm having some real problems setting up a flow trigger condition with SharePoint data.

I have a field called 'Service Lead' (which is a person or group column), and another field called 'Service Lead Text', (which is a text column).

Whenever the 'Service Lead' column is changed I want to update the 'Service Lead Text' column to match. Without a trigger condition this creates an infinite loop in the flow as it's updating itself, so I only want it to run when the fields don't match.

I have tried to research the syntax on this but I'm struggling to get anywhere near. For reference, the 'Service Lead Text' column needs to match the 'Display Name' of the 'Service Lead' person field.

Many thanks.

Hello @danbert1973

Could you share your current flow? I don't understand why an infinite loop is created.

Regards,

Ferran

Hi @fchopo . Apologies, you are right, the flow does not trigger a loop. It does warn me when I create the flow that I need to take steps to prevent an infinite loop, but a standard condition within the flow to compare the fields does appear to be working.

When I added a trigger condition previously, the flow was looping (due to the condition always returning false), as my syntax was clearly incorrect.

However, if anyone can point me in the direction of a comprehensive guide on how to use flow triggers and syntax for different column types/comparisons between field values then that would be a big help, as this is something I need to implement elsewhere.

Many thanks.
