Definition

Logical data base read requests can be transferred to local SAP table buffers and thus considerably increase the system performance compared to data base calls.

Here, a distinction is made between direct and sequential read requests. Sequential read requests can generally only be sent to the 100%-table buffer whereas direct requests to a single table line can also be made to the partial buffer.

The basic prerequisite for buffer access is a corresponding entry in the SAP Data Dictionary for the respective table. The buffer size is defined in the SAP application server startup profile.
