I would like to have our delivery-note number as the report name, so when we print it with a PDF driver, the pdf attachement would have the same name as it corresponding deliverynote. In order words how would the syntax be for renaming the report before printing ?
Don't know if you're still looking for an answer to this but we came across the same problem using PDF Creator.
After a lot of fiddling about with environment variables I finally gave up and just wrote a little method to rename the generated report to whatever I wanted it to be after PDF Creator had done its bit. If you're using a different PDFr (is that a word?) I can't help you, but we've managed to do everything we needed to with PDF Creator Autosave settings., we're emailing PODOS, Invoices etc three times a day.
Oh, just watch for your report name lengths, PDF Creator will truncate them to 31 characters.
