Remove domain from user principle name

[cdmcali]

I am trying to build a flow that uses the get user profile (v2) module and only want to pull the user's username from the system. I would like to remove the @xxxxx.com from the user principal name dynamic content and add it to a column in a sharepoint list. How would I do that?

You basically want to split the e-mail address into two parts; the address and the domain. You can use the split expression to do this, which will generate an array with two outputs. You can then reference each one of theses through the expression in the compose actions.

The expression used in each of the above are:

1. split(outputs('Get_user_profile_(V2)')?['body/mail'],'@') - splits the e-mail address at the @ symbol
2. outputs('Compose')[0] - gets the first item from the split (the e-mail address)
3. outputs('Compose')[1] - gets the second item from the split (the domain)

Here is what happened: 

It put thi sin my sharepoint list: outputs('Compose')[0]

Is this setup right?

I see what I was doing wrong but still not getting the right result: 

Output: split(flowiitsautomation@XXXXX.edu,'@')[0]

I see what I was doing wrong now. I was not using the expression. Thanks!

You need to use the expression builder for the formulas in each of the compose actions. If you have done it correctly, the Inputs will look like the image I posted with a pink box with fx at the beginning. When you click on the input box it should open this menu:

You need to click on Expressions and enter the formula in the fx box. As you build it, you can switch to the Dynamic content tab to get the e-mail field, etc. The three expressions you need:

1. split(outputs('Get_user_profile_(V2)')?['body/mail'],'@') - splits the e-mail address at the @ symbol
2. outputs('Compose')[0] - gets the first item from the split (the e-mail address)
3. outputs('Compose')[1] - gets the second item from the split (the domain)

As long as you did not rename the Get user profile action, and don't rename your first compose action, the bold text above is what should work in the expressions.
