Multi-level universe linking in XIR3.x

[Former Member]

I am trying to link the universes in a specifc manner but due to limitation 'BO only supports one level linking '  I'm not able to implement this design. (describe below).

Consider Unv A(core)is subset of unv B(derived) and universes C&D derived from universe B(attached gif image)

where

B in addition of 'A' sharing common objects to be use by C&D.

C & D are different universes specific to their business domain.

we can not include A into B, since A keeps on changing with every new release of the business application.(with different data model).

A, B,C,D are pointing to different databases having same data structure.

Any thoughts or help on this would be greatly appreciated. Thanks.

Hi Pranav,

Currently in UNV multi level linking is not possible. Also multiple DB connection is not feasible in UNV. SAP is moving from UNV to UNX from SAP BI4.0 and this supports multiple datasources and multiple business layer on single datafoundation.

It is better suggestion to move to BI4.0 for such a requirement.

Hi Pranav,

if you have the duplicate tables in both the core universes , then you will get conflicts.

This is a limitation in XIR3.1.

In BI4.0 you could connect to multiple datasources.

Thanks guys.. but upgrading to SAPBI4 is not an option for us as of now.,Is there any alternative approach we can go for in XI3.x?

Hello Pranav,

Yes we can not do multiplevel linking in linked universes.

As per your description A is a subset of B. A is keep on changing.

So how about Deriving  your universes C and D By linking the universe  A and B both  as core universes .

  C->A,B

  D->A,B

I am not sure how fare i am correct as per your requirement.

Hope this will helps

Thanks,

Hi Pramod,

Thanks for the reply.

I can see another issue in implementing this.....

B is composed of 'A'  and C&D link to B(kernel)

And if we try to link C&D with A explicitly, it will create conflict as all the tables/objects/classes already exists in C&D since they are linked with B.

Is there any workaround we can avoid this conflict..?
