I've created a UDT with 2 fields, ItemNumber (The key) and Description (A multiline text field).

I want to link the ItemNumber to the ItemBillNumber of a work order and display the Description on the Work Order Traveler.

I've added the UDT table in Crystal Reports, and in Links I created the link between the two tables.  I set the link options to Left Outer Join, Not Enforced, and Link Type of =.

After saving everything, when I go and try to run Work Order Traveler Printing I get the following error:

The logic seems very simple, but I'm unsure what I'm missing to make this work.  Any ideas?

I'm on Sage 100c Advanced 2018 (Version 6.00.5.0).
