Flow Posting Duplicates

Posted on by Applications

Good morning all! I'm having an issue with my PowerAutomate automated flow posting an item to a SharePoint list twice.

Here is one SharePoint list my flow references:

And the other list it references:

And it populates the referenced lists to this list:

As you can see the flow worked for an order that contained more than one selection, but for an order that contained only one selection, it duplicated it in the list that combines the two. Any thoughts on why that is and how to fix it? Thank you!

Here is my flow:

Many thanks!

Re: Flow Posting Duplicates

Oh, I think it may be because it's re-posting essentially everything the user created... possibly, not exactly sure. I would like to change the filter array to where if the OrderID column in the Shopping Cart Ordered Items 2 list matches the ID in the Shopping Cart Orders match, it then combines those two and posts to the Full Inventory Order list.

Re: Flow Posting Duplicates

The problem is with the filter array statement you are using. Try the following instead.

1) Use a Data Select on the Get Items output to select just the CreatedBy field

2) in a Compose do a Union() on the output of the data select against itself. (This will give you an array of distinct users in the shopping cart.

3) Create an Apply to Each loop on the output of the Union()

a) Inside the loop filter the Get Items array based on the current loop's value = created by

b) Loop on the results of that filter and create new items for each entry.

So I tried it and I think I messed up somewhere along the way:

Can you assist with identifying where I went wrong? Thanks!

Re: Flow Posting Duplicates

Why is the data select inside a Loop? Here's what it should look like

But taking another look at this I'm not sure what it is you are trying to accomplish. Could you talk about the process a bit more?

Re: Flow Posting Duplicates

So I took it out of the loop, but I'm getting an error within the Union portion:

Is that the wrong expression for referencing the output of the compose?

As for what I'm trying to accomplish:
I have a PowerApp that populates data in two different SharePoint lists, one list is the user information and the other is their order information
I want to combine the information from those two lists to provide a holistic representation of that user's order and their information as well

List with the person's information:

List with the order information:

The list they should both feed into:

This is also the list my other post is referencing; where I want that flow to have a trigger from Delivered to update the main inventory list the PowerApp is referencing to reduce the quantity from that list to limit the option on the PowerApp for ordering.

Thanks!

Re: Flow Posting Duplicates

Union requires two parameters. In this case they are the same, but they have to be listed twice. And they are the output of the data Select, not the apply to each loop.

Re: Flow Posting Duplicates

So I fixed that and it posts, but it's still posting duplicates 😕

I did change it so that it references OrderID to match the ID between the two lists as well.

List1 with 2 orders:
Order has an ID of 37 for the first, and 38 for the second

List2 with 2 orders:
Order has an ID of 37 for the first, and 38 for the second

But when combining with the flow, the first order posted and combined correctly, the second order went crazy:
It has a total of 6 posts per order, so it reposts the first order and double posts the second order. Any thoughts?

Re: Flow Posting Duplicates

Can you post a screenshot of the current flow. In addition to doing the Union() you then need to use the results of that to organize the rest of the flow. Not sure that has happened.
