Misi, I can think of a case where a gap will occur. If I have a form that on submit fires a filter that does a push to a 2nd (or 3rd, 4th, ...) form and that push fails then the 1st form's record will be backed out. With multiple users on the system a second user could create a record in the 1st form during the time that the 1st user is doing the push to the child forms (especially if the push to child forms is conditional on data submitted in the 1st form). This would leave a hole in the sequence of ID on the 1st form.

I have depended on this since version 2.0 of the AR System. There are many cases when it is useful, or required, to have an unbroken serial number. You can build your own workflow to try to accomplish this, but it is not that easy to make it right, and it involves meddling with the filter phasing and database commits... Historically, the next-id-generation has been a dependable counter! Best Regards - Misi, RRR AB, http://www.rrr.se (ARSList MVP 2011) Products from RRR Scandinavia (Best R.O.I.
