Not sure why I'm getting this error

#Caché

Here is the function I'm writing:

/// Returns the participant code based on MSH-4
ClassMethod getParticipant(iSendingFacility As %String) As %String [ Final ]
{
set a = $PIECE(iSendingFacility,"^",1)
set b = $PIECE(iSendingFacility,"^",2)
set sc1 = Lookup("ParticipantCodeMap",a)
if sc1 = "" {
set sc1 = Lookup("ParticipantCodeMap",b)
}
q sc1
}

For some reason when I try to run it I get the following error:

set sc1 = Lookup("ParticipantCodeMap",a) ^ <UNDEFINED>

I tried adding the the default parameter in case it's not finding it but it didn't help. What am I missing?

I must be using the Lookup command wrong.

PHR>Lookup("ParticipantCodeMap","1083601330")
LOOKUP("ParticipantCodeMap","1083601330")
^

I figured it out, I needed to use ..Lookup(), of course.

I guess that you writing an function for rule. And your class where you do it extends Ens.Util.FunctionSet where Lookup is located. Lookup is a method and you should call it as a method, now it is as variable.

/// Returns the participant code based on MSH-4
ClassMethod getParticipant(iSendingFacility As %String) As %String [ Final ]
{
   set a = $PIECE(iSendingFacility,"^",1)
   set b = $PIECE(iSendingFacility,"^",2)
   set sc1 = ..Lookup("ParticipantCodeMap",a)
   if sc1 = "" {
      set sc1 = ..Lookup("ParticipantCodeMap",b)
   }
   q sc1
}

And if you want to call it by terminal, it should be so:

write ##class(Ens.Util.FunctionSet).Lookup("ParticipantCodeMap","1083601330")
