Hello All,
I have read about the read mode and cachemode regarding transaction RSRT. Could you please give me examples for the different kind of read modes and cachemode so that I can understand it better.
I could not get an idea of the data transfer between the database and OLAP for the read modes.
thanks in advance

The read mode determines how much data is read in one go. Read mode A "all" means that data is read for all possible navigations at the first navigation. H means that data is only read at demand, just the data that's needed for the current navigation. X is intermediate, on demand for normal navigation, all for hierarchies. A means usually more data is read from the database is needs to be kept in the application server. H means least possible amount of data.
The Cachemodes determines whereto the OLAP Cache entries are written (to memory, with possible swapping, or directly to persistent storage which is file or database table). An OLAP Cache entry is a result set of a query navigation that is stored for future usage (if the same or very similar navigation is done again). BTW, there is no dependency or connection between Cache mode and read mode (frequently misunderstood feature).
Cheers, Klaus
