Hi, Susan,

The easiest way to determine what code to use in a spec to produce the result you want is to select the 'All codes' specification and print the pick slip, invoice, etc. to screen or Preview it.

The E codes you mention print the optional fields from the Optional Fields tab within the order. The D codes print the optional fields within the item. The D codes print the optional fields within the customer. Of course, to be used, an optional field must first be defined within the company profile.
