SAP EHP7 upgrade invalid object found in pre-processing phase.

Hi Experts,

we are upgrading a new sap EPR6 EHP4 system build via system copy of dev system ans trying to upgrade it to EHP7.

In the Pre-processing phase, its showing below message initially.

then we have released the TR and tried to continue, but we are still left with the bellow message.

we tried checking for invalid objects, but there are no objects found in the TR's we released .

we have also check the TR objects and no such above displayed object is present in the TR.

also tried to activate all the inactive objects in system with program: RSDG_IOBJ_ACTIVATE but still same status.

Please suggest.

Thanks in advance.
