[SalesForce] Concatenate related contact names in a flow

I'd check out the wizard news, this is where I figured out how to do just that.

The basics are yes you'll need to do a loop. Below is an example I did for counting the number of rewards codes we had left and updated the parent object, Reward with the quantity. Therefore this is the same as with your Account and assets... my Reward = Account, and Reward Code = Asset.

In my overview I have other items I do before and during but I think if you just do the steps I've outlined below that's all you need. You don't have to have a decision so that's why I skip that in my instructions below.

Input: Account ID to be used to lookup related assets to count.

Here is an overview of my flow:

1. Get the list of assets for the account:

3. Loop through list. Must create a loop variable, but will not use.

4. this is the way to do a simple N+1 count. Create a counting variable and add to it:

5. Now that you have your count, you need to assign that var back to your Account.Asset Count field: 6. Now just do an update of your account:

You need to distinguish between 'Contact Loop', which is the name of the Loop element and your Loop Variable, which refers to the current contact.

call your Loop Variable something like curContact and use that in your assignment

Also, if you are expecting more than one hit, you need to have your 'matches' path return to the Contact Loop element. right now you have it returning to the outer loop, which means you're quitting after a single hit.
