WHAT IS THE DIFFERENCE BETWEEN ABAP MEMORY AND SAP MEMORY?

Please clarify me.

Hi ,

Within a main session, when ever you start an application program, it opens up an internal sessions with in the main session. The internal session has a memory area that contains the ABAP program and its associated data. So when ever you want to pass data between two internal sessions, then you can use ABAP Memory (i.e import, export).

When comes to SAP memory (also known as global memory), if the data has to be passed b/w two main sessions, we can use SAP Memory(SPA/GPA Parameters). SAP Memory can also be used to pass data b/w internal sessions.

Reward if useful!

SAP Memory

SAP memory is the memory area where all main sessions with in the SAP GUI have the access. We can use SAP memory either

to pass data from one program to other within the session, or to pass data from one session to other. Application programs that

use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set

either for a particular user or for a particular program using the SET PARAMETER statement. Other ABAP programs can then retrieve

the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on

screens

ABAP/4 Memory

ABAP memory is the memory area that all ABAP programs within the same internal session can access using the EXPORT and

IMPORT statements. Data within this area remains intact during a whole sequence of program calls. To pass data

to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of

the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is

then returned to the program which made the initial call, the same process operates in reverse.

SAP memory

The SAP memory, otherwise known as the global memory, is available to a user during the entire duration of a terminal session. Its

contents are retained across transaction boundaries as well as external and internal sessions. The SET PARAMETER and GET

PARAMETER statements allow you to write to, or read from, the SAP memory.

ABAP/4 memory

The contents of the ABAP/4 memory are retained only during the lifetime of an external session (see also Organization of

Modularization Units). You can retain or pass data across internal sessions. The EXPORT TO MEMORY and IMPORT FROM

MEMORY statements allow you to write data to, or read data from, the ABAP memory.
