Link multiple instances of the same universe

Assuming that I have a 'core' universe for providers (doctors), is there a way that I can linked it multiple instances of this universe it a 'parent' in UDT?

In hospital setting there are admitting providers and discharging providers. It would be really helpful to be able to link the providers universe to its parent, twice in my usage-case.

Moreover, has SAP articulated if this will be a feature of IDT in 4.2 SP5, when linked universes arrive?

Linked universes are supported in UDT (UNV) since the dawn of time and Linked IDT universes (UNX) in BI4.x are available either from 4.2 Sp2 or 4.2 Sp4...
But I'm not sure what you mean by multiple instances of this universe.
There is always a core universe and linked universes. those are not instances of the core, even tho they can be created from copies of it.
I think better tag would be Semantic layer :

SAP BusinessObjects - Semantic Layer

A provider may have multiple roles in a hospital setting (an admitting provider and a discharging provider, for example).

Currently, I need to add the provider table twice (using an alias for the second instance) to the 'Inpatient' universe to model these relationships.

I'd rather create a single 'Provider' universe and link it twice to the 'Inpatient' universe. This would make it much easier to manage the provider class and its dimensions.

This doesn't seem to be possible in the UNV universes. I don't know if this is possible in 4.2, as we are currently using 4.1.

Hi Craig,

Have you tried using Business Layer Views in Information Design Tool? Checkout this blog by Michael Welter, search for the text "Linked Universes is Business Layer Views," and please go through that paragraph.

I've actually used Business Layer Views a lot, in 2 ways.

  • To create a filtered group of folders and objects related to each context (so, as many number of Business Layer Views, as there are contexts in the Universe).
  • To display/hide group of folders and objects to specific set of users (which is exactly what Linked Universe do).

Thanks,
Mahboob Mohammed
