How to update address

Hi All

I need to update a standard table with data . one of the field in that is Address number.

I don't know how to generate a address number. I have the address data.

Is there a function module to create a address number in SAP .

Basically I need to link this address to one of the master data that I am creating.

Kindly let me know how to do this.
