Getting User E-mail Address knowing only ExternalSystemID
How can I get the User E-mail Address when all I know is there ExternalUniqueID (ExternalSystemID)?
I assume I use something like:
JoinFieldValue('<User>',[<OwnerId>],'<EmailAddr>')
But how do I get the OwnerId when I only have the ExternalSystemId?
JoinFieldValue('<User>',[<OwnerId>],'<EmailAddr>')
But how do I get the OwnerId when I only have the ExternalSystemId?
