Hi Naresh,
Obi Wan would now probably say: "this is not the functionality you're looking for".
Even though you are working with Z-tables you really don't want to start messing with those from outside the context of the NetWeaver system.
Instead you want to keep the control over all tables in the NetWeaver schema completely to the SAP<sid> user and NetWeaver.
For your data loading scenario, just write a simple ABAP report with native sql or an AMDP to do the copying of the data for you.
Don't spread your code across the landscape and don't loosen access restrictions on your schema.
