From https://knowledgebase.jedox.com/jedox/in-memory-db/rule-templates-query-types.htm, section KPI calculation (by Version), there was a note that "for this query type, the version dimension must have the specific name "Version".
This naming requirement is restrictive to customers, who may require their dimension to be named other similar names like "Scenario" instead.
The idea request is to go by version dimension type, and enable selection of which exactly is the version dimension in the query parameters.
Especially when this Query template type (KPI by Version) was introduced later when some models were existing already and this naming convention was not necessary. Now we can't use this type of query because it is not simple to change all related objects (rules, reports, ETLs). And we would like to use it.
