External Counter
Create a step of the type 'Http Request'.
Method = GET
When this step is started, a link is called, that will add 1 to the last number.
In the link, you refer to a 'type', no need to keep a seperate list of types.
The links below carry 'test' as type.
replace http://sssp/ with the URL to your SSP installation
To fetch the number: http://ssp/AutoIncrement/GetNumber.aspx?type=test&length=10
- this will give the next number of the type 'test', with a length of 10 characters.
To set the starting number to 2000 :
http://ssp/AutoIncrement/Reseed.aspx?type=test&nextnr=2000
To reset the counter to 1 : http://ssp/AutoIncrement/Reseed.aspx?type=test&nr=1
