Customer Master Validity Dates

Greetings all,

I have a requirement to put a validity date for Customers (valid from and Valid to) and have go through a few options but the best I can think of is using the fields in Licenses under Customer Master (VD01)-Sales Area Data-Billing-Licenses. Here are my requirements

1. Using this as DATA RECORDING PURPOSES only to track the valid date from and to only for the customer

Also another question is what would the impact be if I use license just to track the dates? Will it be any impact to lets say calculation of the pricing for the customer or it just serve as a recording purposes only.

Thanks

Regards,
