Hi,

SAP Memory

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). 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 (see below).

ABAP Memory

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

Regards,

Priyanka.

Hi Uttam

SAP Memory is a global memory area which all sessions within a

SAPgui 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,

1.SAP memory is for cross-transaction Applications and ABAP/4 memory is transaction-specific.

2. 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 contents of the ABAP/4 memory are retained only during the lifetime of an external session. You can retain or pass data across internal sessions.

3. The SET PARAMETER and GET PARAMETER statements allow you to write to, or read from, the SAP memory. The EXPORT TO MEMORY and IMPORT FROM MEMORY statements allow you to write data to, or read data from, the ABAP memory.

External session: - when user logs on to R/3 system, the system Createcreates a new terminal session called external session. E.g. System Session.

Internal session: - created by calling a transaction (with CALL TRANSACTION), a dialog module (with CALL DIALOG) or a report (with SUBMIT or RETURN).

For External Sessions, Internal Sessions are available.

SAP Memory is a global memory area which all sessions within a

SAPgui 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'.

In short

ABAP memory -

> Memory related to that particular session

SAP memory -

> memory related to all sessions

Hi Uttam,

SAP memory is the global memory which you can share through out the sessions.

While ABAP memory is a local memory within a session, which is used by a particular program.

I have a humble reuqest uttam, please search in the forum before posting a thread..

This question has been asked hundreds of times. U might be knowing this since u may be a new member to the forum.

Enjoy SDN.

Abap memory and SAP memory are used to store the data for some time

both are used tpo transfer the data between programs

ABAP memory will work in continuous sessions only but SAP memory works in parallel also

ABAP memory is used with export and import parameters and SAP memory with GET and SET parameters
