SharePoint List Item Create/Update (Condition failure)

[Unity]

Hi All,

I'm trying to create a flow that creates or updates items on my child SharePoint list depended on the parent SP list.

Here's what the process looks like (the bold is where the workflow begins):

User fills our MS form>Creates item in Parent SharePoint>Updates child SharePoint

Currently I'm using a condition which compares the title (email) column of both list. I want a condition where one of two happens:

If title (email) matches: Update/overwrite existing entry on child list.

If title (email) doesn't match (no entries listed): Create new line item.

I'm having an issue now, where no matter what I do, the condition is triggering as "false" and a new line item is created on the child list, even if there is an existing item to be overwritten with a matching title (email). I've tried switching the Update/Create with the Yes/No conditions and it still defaults to false and creates a new line item.

Would appreciate any help I can get on fixing this or creating a flow where responses will overwrite previous responses from unique users or create new ones if none exist.

Admittedly, I am not formula savy, so please expand a bit if that is required. Thanks so much!

Below is my current workflow:

Hi!
How many items did you got in your child SP list?
By default 'Get items' response provides max 100 elements, if you have more than 100 and less than 5,000 you should assign a value to Top Count (max 5,000). If you have more than 5,000 you need to activate pagination.

Please note you can also filter results, so your flow would execute faster
Hope this helps

Hi, I currently only have 2 items on the child list. The parent does have 150 entries. That wouldn't be the issue then with the low number count right?

Cheers

Hi @Unity ,

Please refer to screenshot below to create the flow:

The expression in the Filter Query in the Get items action as below:

Title eq '@{triggerBody()?['Title']}'

The length expression in the Condition as below:

length(body('Get_items')?['value'])

Best regards,
