When I click on Select Filter Values and choose single values it takes a long time - several minutes - to produce the list for particular characteristics. In this example I am looking at customer group. The setting in the Query for Filter Value Selection at Query Execution is set to Only Posted Values for Navigation. In the infoobject Selection of Filter Values for Query Execution is set to Q mode Only posted values for navigation. The query is built on a multiprovider made up of four cubes. Each cube has several million records in. Is there an obvious way to speed up the single values list.
