Creating AutoNumber for Microsoft Dynamics CRM 4.0 using Plug-Ins with the help of FilteredView

Create two field as we created..

1) New_uniqueid ( Int)

2) New_id( nvarchar).

If you want AutoNumber as Int , no need to create two fields ,but we wanted AutoNumber as in specific format(OP/DEC08/0000000001) so we reqired to two field.

Steps for AutoNumber:

1) Retrieved the maximum number for entity based on field new_uniqueid.

2) Update both field new_uniqueid and new_id using web service on PostCreate event.

Now Register the Plug-In for any entity on PostCreate event.It will give the AutoNuber in this format(OP/DEC08/0000000001) I.e (first two character of Entity name/three character of current month+ two digit of current year/number with padding(10 digit but customizable))

Don’t forget to pass configuration string when registering Plug-In in Secure Configuration Field in this format

<Config><Database>Machine Name of Database</Database><Domain>Domain Name</Domain><AuthUser>Authenticated User of CRM on behalf of that query will be executed</AuthUser><Padding>number of character for padding </Padding><UniqueNumber>new_uniqueid</UniqueNumber><Id>new_id</Id><LogPath> Log path as D:\CRM\Logs\CrmLog.txt</LogPath></Config>
