BADI not trigger after Upgrade.

We are in upgrade project. we are upgrading from SAP 4.7 to ECC 6.0.

After upgradation we found a new concept in ECC 6.0 call NEW BADI.

Then we have migrated all classical z BADI to New BADI. There we found that

BADI is not triggering in case SAP BADI(MB_MIGO_BADI).

After migrating from classical BADI to new BADI, Then when we are tring to

change/Delete classical BADI it is giving Message "You do not have write authorization for object ZMM_MIGO_TRUCKDATE".
