"Difference Between SAP and ABAP Memory
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.
What is the code to send internal table to abap memory?
This code is from which program you want to export to the ABAP
memory:
export ist_resb to memory id 'ZPPC0122_FD'.
where ist_resb is the internal table name &
ZPPC0122_FD is the include name of my program ZPPC0122.
This code is from which program you want to import from the ABAP memory
import *ist_resb *= ist_resb from memory id 'ZPPC0122_FD'.
where *ist_resb This internal table is the importing program
internal table.*
ist_resb This internal table is the exporting program
internal table.
But remember in both the program you have defined the same internal table
with same structure
Nowadays Export & Import statement is OBSOLETE it gives SLIN CHECK ERROR in
SAP 6.0 Version.
