I do not currently see a config setting to control the format of the PDF attachment "file name" so it appears to be hard coded. Currently, the file name is saved to the server using this naming convention: <Output Document SFM Transaction Id>_<SFID of the header record>_<yyyyMMddHHmmss> when generating a report PDF. For example: Field_Service_Report_a1LJ0000001jGzEMAU_20141021095745.pdf
Can this be configurable? This would be similar to using the ServiceMax Setup --> Event Subject rules which allow you to define the format of the Event Name based on defined rules. pdf outputdocs
