SADR table replacement : Any settings?

Hi,

Since table SADR table will no longer be maintained, i am in process of replacing the same with ADRC.

I need inputs on following points:

1) Impact of replacemnt of SADR by ADRC in different objects.

2) Methods to replace SADR by ADRC at paerticular scenarios. eg: in FM ADDR_GET is there any impact of replacement, as inside this FM there is a query (Select single * from SADR). how to take care of this?

3) Any other specific precautions aur settings to be made?

4) Any online link/help for all these inputs?

Points assured for help.

Regs,

Ags..
