Lookup transform not working - need assistance/feedback please

This isn’t going to be for manager, this is to return the Dn of a Manager and place it in an Identity Mapping. It works for single users, but we have two auth sources in our tenant so when a lifecycleState = “activeDual” - we need it to return both dNs

For example - let’s say I have Joe Smith

Joe Smith has two authoritative sources, Workday and NU SailPoint-

From Workday, MANAGER_ID is 10003977 (Songster, Kim)

From NU SP, SUPERVISOR_NUID is 19497803 (Voss, Joachim)

Right now with ISC’s functionality, the uid:manager field can only house one manager, so I can only use that as a reference for one person. I need to return the distinguishedNames (stored in an Identity mapping on every Identity cube) to the “nmManagerAdDn” and “unmcManagerAdDn” field.
