a!update shows error

You need to specify a target.

[View:https://docs.appian.com/suite/help/23.2/fnc_evaluation_save.html]

When not using a!save() inside a saveInto, you can only assign a target variable to which to save the value to.

Your a!update statement also look odd. Do you mind describing what you want to achieve?

Hey, First you need to use a!save() to save the result into the correct target otherwise you'll get this error. And also the code seems a bit off to me specifically the data part of update function. For updating the status you can try using startProcess() or a related action and by passing the identifier you can update the record with correct status there only and it will be much simpler to configure and understand.

The update function takes an input of some kind of data and outputs the same with one index in the data changed.  a!update( data: {1,2,3,4}, index: 2, value: 7) returns {1,7,3,4}.  But you don't put it anywhere.  In reality you're just doing this:

saveInto: {

{1,7,3,4}

}

What does that even mean?  It's just hanging out in space, and Appian isn't told to use it for anything so it just throws it away.  Really, it gives exactly the error message you've gotten.  If you do save function, save( local!myVariable, a!update( data: local!myVariable ....)) , now you're putting {1,7,3,4} somewhere, specifically you're putting it into local!myVariable.

you can't directly do a!update in saveInto you should use a!save() and store the a!update in some variable

Example:-a!save(ri!data,a!update(logic))
