When using a CU&UC approach (upgrading from 4.6C MDM to ECC6.0) why do we need an additional "ABAP Preparation system"on Web AS6.10 or above?
Why can't we run UCCHECK after upgarding the 4.6C system to ECC6.0 non-UC?
I understand that MDM is not supported in ECC6.0. But the steps we do in this additional system are only 1. running UCCHECK 2. Customer code(printer) page conversions 3. setting DDIC attribute for customer text objects.
I couldn't understand why we cannot do these 3 steps in the upgarded ECC6.0 non-UC system. Please clarify me.
