The ReportEngine.AfterAddField script is called after a field is added to a report in a report wizard. This can be used, for example, to modify the default settings for the field or give a warning if the field shouldn't be used under some circumstances.

Parameters
A reference to the Stonefield Query Application object, a reference to a Report object for the report, and a reference to the newly added ReportField object.

Return Value
Any value (Stonefield Query ignores the return value).

Example
Here's an example that gives a warning if fields from the OEINVD table are included in a report with fields from the OEINVDCRDD table.

for lnI = 1 to toReport.Fields.Count
  loField = toReport.Fields.Item(lnI)
  lcAlias = loField.Alias
