Restriction with stack xml - SAP MOPZ

a.    It’s not possible to create a stack xml file to update just one or two or some specific                components, mopz doesn’t work this way, you need upgrade the complete stack                    together.
b.    It’s not possible to create a mopz just to update patches,we can only just INTEGRATE patches in mopz, but not generate a stack xml file for patches alone. 


For example if customer wants to update the patches of Netweaver    7.30 SP05,he needs upgrade to SP06 or a higher SP level together with the patch levels.
