Cached results have a timestamp, which is compared with the timestamp of the last data load
and meta data change.
If new data is loaded before a cached query is executed again, the OLAP engine states that the
cached entry is out-of-date. It removes the old entry, loads the current query result from the
InfoProviders and writes back this new OLAP Cache entry. The OLAP Cache entry is invalidated
in the following cases:
• Transaction Data Load to the underlying InfoProvider(s)
• Deletion of Transaction Data from the underlying InfoProvider(s)
• Master Data Load (and hierarchies) and subsequent change run of InfoObjects contained
in the query definition
• Currency conversion rate change
This invalidation is also done for meta data changes, i.e. changes to the query structure, and
query generation.
Note that changes to key dates for time-dependent master data does not result in invalidation,
but in an additional cache entry.
In addition, the OLAP Cache can be invalidated and deleted completely via the OLAP Cache
monitor (transaction RSRT 􀃆 Cache Monitor or transaction RSRCACHE). One query entry in
the OLAP Cache can be invalidated by simply re-generating the query.
