how to edit report seize i mean object displayed in the report what is default seize & how much we can extended what is process foe extending i mean steps

I assume by sieze you mean "size" :-)

Garth Jones did a great webcast as part of the BDNA Guru series detailing how to do this. You can get it for free online or from iTunes. I suggest you view that for your answer. BTW... This is really a SQL question, has nothing to do with ConfigMgr.

Could you give me steps to see more number of object in the report & let me know what is default seize & how much can extendable?

I don't think you can change how many rows are on a page but again.... This is NOT a ConfigMgr question. Post it in the SQL forums and someone may know more than we do.

No registry entry needs to be modified unless report builder in opening in 2.0.
