SAP technical upgrade from 4.7 to ECC 6.0

Dear All,

Any one please elaborate the below, which I had found in one of thread.

"technical upgrade the affected areas will be standard SAP objects, screens, menus, programs, transaction codes. "

We are in the initial phase of our technical upgrade from 4.7 to ECC 6.0. The issue here is we are not engaging any outside parties to test & fix the technical upgrade issues. Our hosting partner will do the OS & SAP upgrade only.

Rest of the testing and problem fixing will be done by us.

It will be great help, if some one lists the common issues faced in the technical upgrade to ECC 6.0.

What are all the common problems faced in SAP objects, screens, menus, programs, transaction codes

Please reply,

Thanks in advance,

Raj.
