Wht is ABAP memory & SAP memory?

What does they contain.

explain in detail

[Former Member]

ABAP Memory is accessible within same session(calling a program from another that used ABAP memory), where as SAP Memory is accessible between multiple sessions(independent of the program that used SAP Memory).

1. 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.

2. 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'.

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.

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

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

Hi Prasanth

hope it will help you.

reward if help.

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

SAP global memory retains field value through out session.

set parameter id 'MAT' field v_matnr.

get parameter id 'MAT' field v_matnr.

They are stored in table TPARA.

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.

ABAP memory is temporary and values are retained in same LUW.

export itab to memory id 'TEST'.

import itab from memory Id 'TEST'.

Here itab should be declared of same type and length.
