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.

Visual FoxPro

lparameters toApplication as SQApplication, ;
  toReport as Report, toField as ReportField
local lnI, loField as ReportField, lcAlias, ;
  llHaveCombined, llHaveDetail
for lnI = 1 to toReport.Fields.Count
  loField = toReport.Fields.Item(lnI)
  lcAlias = loField.Alias
  do case
    case lcAlias = 'OEINVDCRDD'
      llHaveCombined = .T.
    case lcAlias = 'OEINVD'
      llHaveDetail = .T.
  endif
next
if llHaveCombined and include fields from 
  toApplication.ShowErrorMessage('You should not ' + ;
    'include fields from Invoice Details on the ' + ;
    'same report as Combined Invoice & Credit Note Details.')
