Hi,

SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters).

ABAP memory is a 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. For further information, refer to Data Clusters in ABAP Memory

Kumar

ABAP Memmory & SAP Memmory

http://www.sap-img.com/abap/difference-between-sap-and-abap-memory.htm

SAP Memory is a global memory area which all sessions within a SAP GUI have access to. This allows for passing data between sessions. The SET PARAMETER ID and GET PARAMETER ID statements are used to manipulate the SAP Memory.

SET PARAMETER ID 'MAT' field p_matnr.

GET PARAMETER ID 'MAT' field p_matnr.

ABAP Memory is a memory area which all programs in the call stack

within the same internal session can access. The EXPORT and IMPORT statements are used here.

export p_matnr = p_matnr to memory id 'ZTESTMAT'.

import p_matnr = p_matnr from memory id 'ZTESTMAT'.

Hi Munjunath,

ABAP Memory: is a memory which is used as internal memory which allocates in internal session only. Internal memory is allocated for programs performing in a internal session.Every program has its own ABAP memory.we can pass data between programs by using IMPORT and EXPORT.

SAP Memory: is a memory which can be allocated between sesions.Every session has programs.SAP memory is allocated for for every session. it is used to pass data from one program to another program in another session by using SET/GET Parameters.

if it useful, reward points.

Thank U,
