0CS_Item with time-dependent hierarchy

Dear Experts,

we are discussing pros and cons for a time-dependent item catalog (characteristic 0CS_item with time dependent hierarchy in BW) within consolidation SEM BCS 4.0. Does anybody has experiences on this topic?

I am quite sure it will be a performance issue and it means additional reporting effort (e.g. using reference period/year in the report comparing different hierarchies).

I am not sure if there are any other risks so I it would be great if anybody has some hints.

Thanks in advance,

Birgit Laux

    Birgit,

    Some other things to consider:

    - frequency of changes to item hierarchy. Could lead to a lot of item hierarchies in BW over time.

    - hierarchy validity date does not seem to be displayed when running web queries and thus makes it difficult for the user to select the correct hierarchy when executing the query. Still looking for a fix for this.

    - greater complexity in overall design. Is it really necessary to achieve correct financial statement presentation?

    Virtual cube performance is not great but you could implement the data mart which provides typical BW query performance.

    I stayed away from setting the item as time dependent for these reasons.
