What is ABAP memory?
The ABAP memory is the temporary memory that is used by ABAP programs and objects that use the same internal session - or the same memory area - for all activities. Compared to SAP memory, which is considered global memory, ABAP memory is local memory. The ABAP memory is independent of the ABAP programs or objects that generate it, so that values can be transferred via different objects or programs regardless of its properties. This is particularly useful for programs that are live in the same session.
ABAP programs and objects mainly use two types of memory: ABAP memory and SAP memory. ABAP memory is quite limited compared to SAP memory and can be accessed from an internal main session, while SAP memory is accessible to programs or objects outside the main session. The ABAP memory is one of the most important tools available to programmers for transferring values across programs. It helps in minimizing database usage and also helps in maximizing the speed and efficiency of the applications. The values transferred via ABAP memory are not saved in a SAP table. Instructions with the keywords 'Export in Memory' and 'Import from Memory' are used to access the ABAP memory. 'Export in Memory' is used to read data from the ABAP memory, while 'Import from Memory'.
