Answer 1

I am looking through the API calls in FDM Workbench, but cannot see the table (tPOVPartitions) you mentioned listed. Is this the correct name? And do I just use the function listed in the object browser to run the query?
Furthermore (going back to my initial thoughts of using strFile), it appears that although the variable contains the .Dat filename and path, the actual file is non-existent when "BefExportToDat" is executed:
Error:
Error: Export failed.
Detail: File not found.
This would make sense, but it does make the variable "strFile" a little pointless since one cannot make use of the file in this particular event script. Do you please have any thoughts on this?
