LTRC transaction options

Hi

I am new to SLT and trying to understand the options available. I have access to ECC IDES system EHP7 and I am able to go to transaction LTRC.

I notices that the target option has lot of drop down options ( MS SQL, ORACLE and so on ) but its defaulted to HANA and I dont have a option to change this ( Grey-ed out). Am i missing any configuration ? Or IDES system donst support SLT to other Non-HANA DB ?

Thanks

Raj
