Resolution

To resolve this issue, do one of the following:
  • Edit your outbound document definition to use a string datatype instead of a date datatype.

    -or-

  • Create a custom Visual Basic Script functoid that will convert the output of the Database Value Extractor into the ISO 8601 format.
Use the following sample code from the Date Functoid to convert the date:
Function FctConvertDate(DateIn)
Dim dt
Dim y
Dim m
Dim d

dt = DateIn
y = CStr(Year(dt))
m = CStr(Month(dt))
d = CStr(Day(dt))

If Len(m) = 1 Then
     m = "0" & m
End If
If Len(d) = 1 Then
     d = "0" & d
End If

'ISO 8601 format
FctConvertDate = CStr(Year(dt)) & "-" & m & "-" & d
End Function
