Hello Wema:

Are you looking for the time that the invoice was Created or when it was Printed? Are you using Order Entry or Adagio Invoices?

The specification codes under the different circumstances are:
-Order Entry & time of Invoice Creation: E58
-Order Entry & time of Printing: M17
-Invoices & time of Invoice Creation/Edit: Date available, can't find Time
-Invoices & time of Printing: S02

In either case you would open "Maintain Specifications", call up your Invoice form, insert the code on the header (or footer) and save the change.

To see a list of all available specification codes, open the Adagio sample data, open the specification editor and look for a sample form that includes all codes. For OE it is called "OE All Codes to Mar 08". For Invoices it is called "All Specification codes 8.1A". These names assume you are using version 8.1.
