Hi Vickie
When in doubt, open up the Specification Editor, and browse to the \Softrak\OEWIN\Samdata folder, change the data selector to SAM, and open the spec called OE$ALL.SAM. Then save that spec in your data folder, with your data extension.
Selecting this spec when printing a work order will allow you to see all of the possible spec fields and what they will return.
