How to get Appian current logged in USER NAME. I just need login id as text for

Hi,

I am trying to get a username or email anything so I used loggedInUser() under display value in interface and choose a rule input to save it to data type which inturn is linked to a db, but when I submit form the record view is not displaying user name, it shows empty.

On other hand when I use rule input even for display value it is taking my input text and showing up in record view.

I just want to auto pick up username and insert in my record view which will populate my Datastore(Appian DB)

In a User Interface a save to a rule input will only be triggered as the result of a User Interaction on the form. If you want the loggedInUser() saved to a column in a database table then set it in the process model after the User has submitted the form.

thanks, @Stewart I will try this and update back if it works, I am anyway using write to data base in the process model

However other values which should be manually filled are getting saved into a database table, only this auto-generated value "loggedInUser()" is showing up as empty/Null

As I said your values will be passed to the rule inputs when a user action is made in the form. You could therefore set the value of your target the rule input with fn!loggedInUser() as part of the save of the 'Submit' button. You can test this in the form itself to prove that it's working. If the value is till not makign its way tio the database then:

1. check that the rule input is mapped to an activity class (ac!) variable of the User Input Task in the Process model
2. check that the ac! varibale is mapped to a pv! and the pv! is mapped to the relevant attribute of the CDT OR the ac! is mapped directly to the relevant attribute of the CDT
