Get the next new Item number

Hi Experts,

Is it possible to get the next new item number for the service contract.

For example we have the service contract like 40100924, for this we have the item numbers (10,20,30)

The neext new item number is the 40.

How we can get this number.

Could any one suggest is there any FM available to get that number.

Thnx,

Jaya.
