Invoice Line Requester Name Approval Rule

Summary:

Invoice Line Requester Name Approval Rule

Content (required):

Trying to put a rule for the requester of the invoice line order to approve the invoice.

Starting Participant: HierarchyBuilder.getPrincipal(Invoice Line.Requester ID,-1,"","")

Top Participant: HierarchyBuilder.getPrincipal(Invoice Line.Requester ID,-1,"","")

The warning we are getting: RUL-05721: The result type of the expression is "Long" but should be "String".

I also tried the following:

HierarchyBuilder.getPrincipal(Invoice Line.Requester Name,-1,"","")

Top Participant: HierarchyBuilder.getPrincipal(Invoice Line.Requester Name,-1,"","")

The approval workflow ends in error.

As for requestor from the invoice header to approve, it worked, but that field is not auto-populated, so we're looking for a line-level rule.
