Trying to port my schema from v3 to v4, and I'm having trouble with aggregate tables. The docs haven't even been updated yet to describe what everything is which is frustrating, and the Mondrian in Action book briefly talks about it, but that's it. There is also nothing on the internet to help with problems either.
I'm getting the following error:
Caused by: mondrian.rolap.RolapSchema$PhysSchemaException: Could not find a path from agg_year_employment to any of [Employment as employment]
at mondrian.rolap.RolapSchema$PhysSchemaGraph.findUniquePath(RolapSchema.java:1211)
at mondrian.rolap.RolapSchema$PhysSchemaGraph.addHopsBetween(RolapSchema.java:1161)
at mondrian.rolap.RolapSchema$PhysSchemaGraph.findPath(RolapSchema.java:1307)
at mondrian.rolap.RolapSchemaLoader.registerExpr(RolapSchemaLoader.java:2222)
...
Here is the relevant sections from my schema:
So how is this "linked" to the Employment fact table? Do I need to use Link tags in PhysicalSchema?
