Passing Data From One ABAP Program to Another

Passing Data From One ABAP Program to Another

Many a times it is required to pass data from one ABAP program to another. This can be done using the EXPORT and IMPORT statement in ABAP. Please find the examples given below.

REPORT ZEX_MEMORY .

Data: D_MEMORY(20) value 'BEFORE EXPORT',
          MEMID(5) value 'MEMID'.


    write:/ D_MEMORY.

    EXPORT D_MEMORY to MEMORY ID MEMID.

    D_MEMORY = 'MOVED BEFORE IMPORT'.

    write:/ '"Value before import"', D_MEMORY.

    EXPORT D_MEMORY to MEMORY ID MEMID.

    write:/ sy-subrc, ' "Value after import"', D_MEMORY.

    FREE MEMORY ID MEMID.

    IMPORT D_MEMORY from MEMORY ID MEMID.

    write:/ sy-subrc, ' "Value after freeing memory"', D_MEMORY.

As you can see from the above example the field D_MEMORY can be exported to memory and then imported back. Once you are done with importing the value you need to FREE the memory ID. Please make sure that you free only the MEMORY ID exported by you.

---

Here we are using the syntax given below.

EXPORT filed1 to MEMORY ID MEMID.
IMPORT filed1 from MEMORY ID MEMID.
FREE MEMORY ID MEMID.

---

You can also export field contents to memory from one program and import them in another program. Please see the code given below.

PROGRAM1    Passing Values from one program to other in SAP ABAP

REPORT ZEX_MEMORYEXPORT .

Data: D_MEMORY1(100) value 'Exportfromprog1'.


EXPORT D_MEMORY1
       D_MEMORY2 FROM 'EXPORTING THIS FROM PROGRAM1'
       TO MEMORY ID 'MEMID1'.

SUBMIT ZEX_MEMORY1 and RETURN.


write:/ sy-subrc, D_MEMORY1.

The above program will call the following program, since the value 'EXPORTING THIS FROM PROGRAM1' has already been exported to ABAP Memory it can be retrieved as shown in the program given below.

PROGRAM 2  Passing Values from one program to other in SAP ABAP

REPORT ZEX_MEMORY1 .


Data: D_MEMORY1(100).

EXPORT D_MEMORY1 TO MEMORY ID 'MEMID1'.

IMPORT D_MEMORY2 TO D_MEMORY1 FROM MEMORY ID 'MEMID1'.

WRITE: / SY-SUBRC,  D_MEMORY1.

As shown in program 1 and 2 the value 'EXPORTING THIS FROM PROGRAM1' is passed from ABAP memory from one program to the other.

SAP ABAP Calling Executable Programs

SAP ABAP Calling Executable Programs

If you wish to call an executable  ABAP progra from another ABAP program/report you can do so by using the SUBMIT statement.  For example your wish to call program <CALLEDPROGARM> from the current program <CURRENTPROGRAM> then the control can either be passed to the called program or once the called program has finished its job the control cab be RETURNED to the calling program. Please find the Syntax below.

SUBMIT prog|(variable) [AND RETURN] [options].

The called program name can be directly mentioned in the code or you can dynamically pass the called program using a variable. As mentioned above once the called program finishes its job, the program can be either returned to the calling program using the RETURN option. In case RETURN is omitted then all data and list levels of the calling program (the entire internal session) are deleted. After the called executable program has finished, control returns to the level from which you started the calling program. Whereas if the RETURN option is used then the control is returned to the statement after SUBMIT and the calling program continues its operation.

In case the called program has a selection screen then the SUBMIT statement can be used with the various options as shown below.

SUBMIT             [VIA SELECTION-SCREEN]
                        [USING SELECTION-SET var]

The following code will make things clearer.

The following is the called program

The following the the calling program.

REPORT ZEXERCISE_SUBMIT .


Data: d_value1(10).

d_value1 = 'Test1'.

SUBMIT ZEXERCISE_1 via selection-screen and RETURN.

write: d_value1.

---

EXERCISE

Please try the following options.

1) From the calling program's SUBMIT statement remove the and RETURN Option and see the result. If and RETURN is removed the the value of d_value1 is not written on the screen. Where as if and RETURN is not omitted then the control is given back to the called program at the next statement after SUBMIT and the value of d_value1 ie Test1 is written on the screen.

2) Create a variant for the program (see creating variants for ABAP Programs). And use the statement given below. And see the result. Note that SORD is the variant name and you need to replace it with the name given by you.

SUBMIT ZEXERCISE_1 using selection-set 'SORD'.
