Abdul,
Agree with Wes. Seems ABAPer's believe you are the approving authority and hindering access. Once they know it is out of your hands and they have to follow a formal process of approval, most ad-hoc requests drop.
A few genuine ones do come up now and then (once in a bluemoon) and that can be given via GRC Firefighter (if you have GRC in landscape) else with proper business approver. Have a talk with the Data Owner (Client side) and formulate a plan if don't have one already.
