SAP Query - Modfication/Changes

Hi Experts,

I am new SAP Query, so i have come up with this issue. Please help.

I have an infoset query with me, also a SAP query and a transaction with some Z transaction code, the program name as taken from System->Status is AQZZZSD=========Z_SD_ORD_WO_ST.

1. Now I can see code in the program, but I cant see that much of code in the SQ02 under extras tab.

2. Moreover, I have to change the code to address new requirements. How can I change the code in a SAP query???

What are the ways to change an existing SAP query's code ???

Thanks,

Chandan
