The Field Grid perspective allows the author to scroll through all data points (DTAs) and identify any invalid rules or missing GDD names/Public names. This is helpful after the PTRs are complete to be able to quickly scroll through all of the PTRs and identify possible validation issues. Potentially invalid rules will be highlighted in yellow, but note that some rules that will not validate in the field grid are actually valid rules. The Outline Editor perspective is much more accurate for validating PTRs.
The perspective is available by clicking the Field Grid tab in the document pane. The Field Grid is available for both dynamic and static documents. This is an example of the field grid perspective in a dynamic document. 
The following values are used to define a data field and are presented in the Field Grid:
- Rule Name: A unique ID for each data field entered.
- Business Logic: A plain English description of the purpose of the data field, or rule. This is not used for EPM content.
- Product Technical Rule: The PTR represents the processing instructions, or code, that defines the behavior of the rule. This is not used for EPM content.
- GDD Name: The data name used for VMP tech/board and E-Forms content.
- Public Name: The name used to define the rule for the BSI tech/board and E-Forms content.
- Substitution Name: The data name used when completed with values from the Edit Instance screen.
- Enterprise Name: This value is not used in current authoring practices.
