Hi,
I need the output as an email of username. I have tried create an expression rule below but getting the below error. Could anyone suggest regarding the issue in the expression rule and correct me what needs to be updated.
=if(and(not(rule!APN_isEmpty(ri!user)),isusernametaken(ri!user)),user(touser(ri!user),"firstName") & " " & user(touser(ri!user),"lastName"),"NA")
Problem: An invalid expression has been encountered in a task.
Details: ERROR:An error occurred while evaluating expression: =rule!prmFormatUserAsEmailAddress() (Expression evaluation error in rule 'prmformatuserasemailaddress': Rule 'prmformatuserasemailaddress' has 1 parameters, but instead passed 0 parameters.) (Data Inputs)

you must pass your parameter value when you call this rule (ri!user does not passed to the rule when you called)..

see your massage error :
Rule 'prmformatuserasemailaddress' has 1 parameters, but instead passed 0 parameters.) (Data Inputs)

Currently the model is using a PV projectmetadata to get the email address. I would like to modify this PV and instead we want to create an expression rule like prmFormatUserAsFirstLast to get the email address then we can reference the rule in the process model.
For this I have created a expression rule prmFormatUserAsFirstLast

=if(and(not(rule!APN_isEmpty(ri!user)),isusernametaken(ri!user)),user(touser(ri!user),"firstName") & " " & user(touser(ri!user),"lastName"),"NA")
but getting the error.

Could you suggest what needs to be added so that I get an email address here.

This is the expression rule I have added instead of using a process variable. rule!prmFormatUserAsFirstLast()
=if(and(not(rule!APN_isEmpty(ri!user)),isusernametaken(ri!user)),user(touser(ri!user),"firstName") & " " & user(touser(ri!user),"lastName"),"NA")
but getting the error.

I would also suggest that in this and your previous rules, the touser() is redundant as you're already passing in a user object.

Thx Philb ... I have update expression and process mode. It is working now. rule!prmemailaddress ---> =if(and(not(rule!APN_isEmpty(ri!user)),
isusernametaken(ri!user)),
user(touser(ri!user),"email"),"NA")

=rule!prmemailaddress(pv!projectMetadata.projectInitiator)
