    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, refer to Data Clusters in ABAP Memory.

    For more information, please check this links.

    Hi

    welcome to SDN forum

    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.

    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/4 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.

    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.

    • sample program for ABAP memory.

      data: it001 type table of t001 with header line.

      select * into table it001 from t001.

      export it001 = it001 to memory id 'ZABAP'.

      clear it001. refresh it001.

      import it001 = it001 from memory id 'ZABAP'.

      loop at it001.

      write:/ it001-bukrs, it001-butxt.

      endloop.

    hI

    ABAP MEMORY:To transfer the Data between the Programs Running in the Same Session We can use.

    Eg:

    Calling Report.

    REPORT ZREP1.

    DATA : ITAB TYPE TABLE OF MARA.

    SELECT * FROM MARA INTO TABLE ITAB.

    EXPORT TEMPTAB FROM ITAB TO MEMORY ID 'M1'.

    SUBMIT ZREP2 AND RETURN.

    Called report

    REPORT ZREP2.

    DATA: IT_MARA TYPE TABLE OF MARA.

    DATA WA TYPE MARA.

    IMPORT TEMPTAB TO IT_MARA FROM MEMORY ID 'M1'

    LOOP AT IT_MARA INTO WA.

    WRITE:/ WA-MATNR.

    ENDLOOP.

    SAP Memory:

    It is used to pass the Data to Screen fields or Read data from Screen Fields.

    It can be used to Transfer data from one Session(window) to another within the Login.

    DATA : V_KUNNR TYPE KNA1-KUNNR VALUE 1000.

    SET PARAMETER ID 'KUN' FIELD V_KUNNR.

    CALL TRANSACTION 'XD03' AND SKIP FIRST SCREEN.

    REWARD IF HELPFUL.

    Hi

    <b>ABAP Memory</b>

    Memory area within every main session, which the programs with the statements EXPORT and IMPORT can access. This memory area is maintained via a succession of program calls (call sequence).

    <b>SAP Memory</b>

    Memory area of application server, which all main sessions of a user session access jointly. ABAP programs have access to SPA/GPA parameters stored in the SAP memory.

    <b>Reward if usefull</b>
