Difference between Drawing Power and Outstanding Amount in SBI SBI SURAKSHIT HL A/c ?

Hi,

I am SBI Home loan customer with SBI SURAKSHIT HL A/C. When I log -in to my internet banking, I see Drawing Power, Outstanding Amount and Limit.

Kindly help me to understand differences between outstanding amount, drawing power. More over today I transferred some money from my Saving A/C to Loan A/C. I see only the transferred amount was getting deducted from Outstanding Amount. 

When the Drawing power gets reduced? Should I assume that outstanding amount is the remaining amount, I need to pay back to the bank. Please clarify. Many thanks in advance!
