Some descriptions from "How to Enhance SAP HANA Live "
The SAP HANA Live scenario as delivered contains “Private Views” which are the base views that directly use the SAP Tables.
The next level of views is the “Reuse Views” which consist of one or more “Private” views joined in combination to produce a composite view that forms a reusable unit related to a particular area or function within the system.
So 'Private' contains SAP Tables
And 'ReUse' contain Private views in combination.
Got it !
I now look in "_SYS_REPO"."ACTIVE_TAGS" and pick out a random 'Private' view. 'MaintOrderHeaderCosts'
This 'Private' view contains
> SAP TABLE : "PMCO"
> ReUse view : "MaintenanceOrderHeader"
Then let's look at a random reuse View : "MaintenanceNotificationHeader"
This does indeed contain other reuse views, but it also contains base ECC tables
e.g. QMEL,JEST,QMIH, ILOA
So private views CAN contain reuse views as well as SAP Tables
And reuseViews can contain both as well.
So what's the difference ?
I hope you can see why I am confused ?
I am also thinking that my first example blows the 'copy & extend' model out of the water.
Any comments or clarifications welcome ...
