13. Modularization Techniques

Question 1

When you declare a subroutine, you are identifying the_____ When you call a subroutine, you must specify the______

Answer 1

Formal parameters, Actual parameters

Question 2

When using parameters, they must be passed to the subroutine using one of the following three methods.

Answer 2

Pass by value, Pass by value and result and Pass by reference

Question 3

Pass by value-method

Answer 3

When the subroutine is called, a copy of the value of the data variable is passed to the formal parameter. The formal parameter has its own storage location (memory).

Question 4

Pass by value and result-Method

Answer 4

In addition to the above, at the end of the subroutine, the value of the formal parameter is passed back to the actual parameter assigned to it.

Question 5

Pass by reference-method

Answer 5

The formal parameters do not have a separate storage location. Instead, the address of the actual parameter is passed to the formal parameter. Changes to the value of the formal parameter are immediately reflected back in the actual parameters.

Question 6

PERFORM statement

Answer 6

to call a subroutine.

Question 7

FORM/ENDFORM statement

Answer 7

to define a subroutine.

Question 8

USING keyword

Answer 8

allows you to specify the data variables to be passed as parameters.

Question 9

CHANGING keyword

Answer 9

when specifying formal parameters to define a pass by value and result.

Question 10

Local data

Answer 10

is any variable or structure that is defined within a subroutine.

Question 11

use this option if you want the variable to be re-initialized with the default value every time it enters the subroutine.

Answer 11

DATA

Question 12

use this option if you want the variable to remember what the value was the last time it was in the subroutine. It will not be re-initialized based on the definition.

Answer 12

STATICS

Question 13

Function modules

Answer 13

are general purpose ABAP routines that can be called from any ABAP program. The benefit of function modules lies in their reusability, which saves developers from creating redundant code and increases programming efficiency.

Question 14

Function builder

Answer 14

These function groups are collections of logically related functions that share common program context, such as global variables, at run time.

Question 15

Parts of a function module

Answer 15

Administration, Interface, Documentation, Source code, Global data and main program

Question 16

Administration-part of a function module

Answer 16

Attributes such as the function group and short text

are assigned

Question 17

Interface-part of a function module

Answer 17

Parameters such as import/export and exceptions are defined.

Question 18

Documentation-part of a function module

Answer 18

Maintain documentation of function module

Question 19

Source code-part of a function module

Answer 19

Define actual ABAP code for function module

Question 20

Global data-part of a function module

Answer 20

Define data available for all function modules belonging to the assigned function group

Question 21

Main program-part of a function module

Answer 21

Program where all of the function modules of a function group are stored as well as the global data

Question 22

Funtion groups

Answer 22

Are collections of logically related functions modules. Specification of a function group is required when creating a function module.

Question 23

5 different interface parameters

Answer 23

• Import parameters
	• Changing parameters
	• Export parameters
	• Tables parameters
Exceptions parameters

Question 24

Import parameters

Answer 24

are those variables that will be imported from the

calling program.

Question 25

Export parameters

Answer 25

are those variables that will be exported to the

calling program.

Question 26

Changing parameters

Answer 26

are those variables that will be both imported from and exported to the calling program.

Question 27

RAISE

Answer 27

use this version if you just want to set SY-SUBRC and let the calling program do the logic to interpret the importance and send a message or take any other action.

Question 28

MESSAGE … RAISING

Answer 28

use this version if you want the function module to also capture specific message information that you can later access in your main program.

Question 29

SE37

Answer 29

ABAP Function Builder

Question 30

EXPORTING statement

Answer 30

to pass data from the calling program to the function module.

Question 31

IMPORTING statement

Answer 31

to transfer data from the function module to the program.

Question 32

TEST/EXECUTE statement

Answer 32

Test a function module

Question 33

DESTINATION statement

Answer 33

tells the SAP System that the called function runs in a system other than the callers. is required for the remote call of a Function Module.
