How to get and install TDMS licenses for ECC, BI , CRM?

This question is related to the following link:

TDMS for CRM + BI

In above link, it's said that "TDMS BI & CRM needs to be licensed separately".

I've looked into SMP quick link->licensekey and found no license for TDMS.

So would you please kindly tell us

1) where to get the TDMS license?

2) how to install the license?

Thanks a lot!
