Error in a!save : You must specify a variable to save into, such as ri!name << fn!sum. Received: List of Map.

Can you try to use proper keyword syntax like below.

a!save(
  target: local!something,
  value: rule!something()
)

Oh dear .... It's a while ago I saw > 500 lines of code in a saveInto.

The lines 344 and 464 and look suspicious. You cannot store data to a local that way. Use an a!save().

BTW, do you really need to dynamically construct SQL statements in Appian and send them to a stored procedure for execution?

there you have a!saves() and local variable declaration in a saveinto? 

any deeper sense, which I might miss for this kind of {}-structure in the saving logic?

small hint:

you dont need the if at line 530. just rule!apn_isblank is enough.
in line 522 you don't need the and()

Agreed with this - local!sqlData and local!sqlResult are being invoked in an unsupported way and i'd be surprised if it even worked by accident.  I believe the error in the screenshot is likely directly related to these two lines, since they are not a valid save operation.

Yes, this will cause the issue.  The local variable declarations in saveInto should also be wrapped in a!save() instead, such as here:

And here:

You can replicate this error by trying this in a simple interface:

a!localVariables(
  local!buttonVal,
  a!buttonLayout(
    primaryButtons: {
      a!buttonWidget(
        label: "Save",
        saveInto: {
          a!save(local!buttonVal,"test"),
          local!test: a!map(id: 1) /* This line is not correct! */
        }
      )
    }
  )
)

To add to the thread this error also will occur for the situation where you have a rule input defined as an expression, not a variable.  Such as an a!save(ri!value,"test"), where the input definition in the user input task is something like a string "value here", vs a variable such as pv!value.

this looks familiar, lol...

Ha, oops!  But I agree! 

Sometimes ri!name << fn!sum error occurs when the evaluation of an if condition returns array of true or false instead of single value in the saveInto parameter.
