Cannot compile Fast Formule for payroll element

Summary:

Hello experts,

I should create a fast formula returning a recurring payroll element (the element is MBO Target) loaded to employees in the current year.

However, when compiling it, the system returns an error message.

Below the fast formula I'm trying to use:

default for MBO_TARGET_IMPORTO_ASG_ENTRY_VALUE is '0'

mbotarget= MBO_TARGET_IMPORTO_ASG_ENTRY_VALUE

return mbotarget

What's missing?

Thanks in advance for your time!

Kind Regards,

Valerio
