Increase size of tablespace

Dear All,

On SAP tcode Db02, say the SIZE of Tablespace PSAPSR3USR is 50 GB and free space is 5 GB. The total size is also 50 GB.

the autoextend is NO. On DB02 - space overview, the free space on database is 200 GB.

Now i want to increase the SIZE of Tablespace PSAPSR3USR from 50 GB to 70 GB, how do I proceed?

If i add 10 GB of datafile using BRTOOLS, will the size of tablespace increase from 50 to 60GB?

Thanks,

Gavisht
