Hi Pranav,
The system which i am refering to is EHP4. Since your system is in EHP6 there might be few more fields are added(Slight changes in table structure) to the table.
I hope you shoud get the required values/data from AGR_1252 table, even if the versions are difference.
Check if the table descripton is "Organizational elements for authorizations", if yes then this table will have the required data.
Else search for table in SE11 with AGR_*, and choose the table having the description "Organizational elements for authorizations" or contains a keyword "Organization".
In EHP4, The table looks like below.
Thanks & Reagrds,
