start auto id from specific number

Hi people!

How can I resolve this,

I have 1000 records, but the numeration starts in 100,000.

For example the first record is the 100,001 and the last is the 101,000.

Actually this ID is generated in MM automatically, but now when you want to create a record, it will be created from MDM and then send the important data to MM.

So I have to import the records, and then start the auto id, from 101,000. How can i solve this?

thanx
