To generate data from a custom field on a template, the custom field ID number will need to be determined. To identify the ID number, navigate to Project Menu > Set Up > Project Configuration.
Navigate to the "Fields & Equipment Types" tab and locate the section for the appropriate custom field type (e.g., Doc Code/Card Fields, Equipment Fields, etc.). In the appropriate grid, find the field in question and identify the value in the variable/field column. The numerical value is considered the ID number.
Example: The ID number of the "Note" doc code/card field is 1. To show this value on a document cover page, use the <Document_CustFieldX> variable and update the "X" to the ID number (<Document_CustField1)>
