shared memory
Memory area of an AS Instance, used by the ABAP runtime environment as a repository for programs, program data, buffers, and so on. In the shared memory of the current AS Instance, ABAP programs can either access data clusters in cross-transactional application buffers or shared objects in the shared objects memory. The maximum amount of shared memory that can be occupied by the different consumers is defined statically using profile parameters. Transaction ST02 (SAP Memory Management) shows the current occupancy of the shared memory and the corresponding profile parameters.
