In MSCRM 2011, there is out of the box auto numbering on several entities such as quotes, cases (incidents).
The 3 character prefix, e.g. QUO, CAS is followed by 5 digits, then 5 alphanumeric characters by default.
Looking at our CRM database, the references created have ranged from
CAS-00001-XXXXX up to CAS-97500-XXXXX
XXXXX is just 5 random chars and the numerical part above is incrementing one at a time chronologically and we're a little concerned what will happen when it reaches 99999. Does it automatically go back to the beginning but use a different 5 characters after the 2nd hyphen?
Our next approach is to make a console app to insert 100000 quotes into our database but would be good to avoid having to do this if someone knows exactly how it works. When I Google for it, I just get people's solutions for autonumbering with very little about how CRM's own numbering works.
