Unable to create table in SE11

Hi All,

I am trying to create a new table in SE11, but unable to do the same. The system pops up a dialog for access key. Could anybody help me understand on this key & where would I get this key from ? Is there any default value/key for this?

I am using IDES (ECC 6) to get to know more about ABAP.

Thanks & Regards
