Summary :
SAP Note addresses an issue where switching data export from XSTRING format in OLAP cache to an internal table causes format errors during IMPORT operations across servers. This occurs because the system expected data to be stored as XSTRING in media (cluster table and shared memory), and not as an internal table. The solution includes expanding the deletion functionality in reports, allowing users to clear all cache storage media on application servers without changing cache modes. From Support Package Stack 31 onwards, cache clearing across servers is automated by RFC. Prior to this, manual report execution on each server is necessary with specific configurations.
