PROBLEM:
Most of my Crystal reports when deployed do not require the .TAG files but once in a while they do -- what is the rule of thumb?

ANSWER:
The Crystal Connectivity Kit Readme states that "In order to see the field names of your DataFlex data files (*.DAT), the corresponding *.TAG files need to be located in the same directory the DAT files are."

Basically, you need the .TAG files whenever you work with field names. Although field names are stored in the report itself, mapping a field name to a field number still requires the .TAG files. The following situations describe when mapping will occur and the .TAG files will be needed:

- When the user has CRW and is creating his own reports
- When using subreports, where you normally 'link' the subreport to the main report using a selection formula
- When creating a selection formula from a VDF program


As a basic rule, always add the tag files to the same directory where the .DAT files are.
