Hi

1)

SAP Repository means the group of all objects like programs, business objects, classes, Dictionary,Web dynpro,BSp, test objects like Ecatt and all other objects

2) 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 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

1). SAP Repository it is central data repository where all objects(like.. programs, dictionary ,business objects ,packages,function groups,classes.......) are stored. T-code for repository is se80 .

2). SAP memory and ABAP memory to pass data between different programs.

The SAP memory is a user-specific memory area for storing field values.

it si available in all of the open sessions in a user's terminal session, and

is reset when the terminal session ends. All external sessions can access

SAP memory. You can also read the memory areas from the SAPmemory

using the ABAP statement GET parameter ID field.

The ABAP memory is initialized after the program is called.ABAP memory

is also a user-specific, and is local to each external session. you can use it

to pass any ABAP variables(fields, structures, internal tables,complex objects)

between the internal sessions of single external session.

Each external session has its own ABAP memory,when you end an external

session, the corresponding ABAP memory is released automatically.

if it is useful, reward points.
