• The subscreen screen is called in the processing logic of the main screen with the instruction ‘Call CUSTOMER-

SUBSCREEN’. This call is inactive and will be skipped when the screen is processed until the customer has activated the relative enhancement screen.

Subscreen area

12

We will be working with the enhancement ‘MM06E005’ it has several screen exits but we will be working with the first screen ‘SAPMM06E’ screen no ‘101’ which will be calling the sub screen ‘SAPLXM06’ screen no ‘101’ which is not existing and has to be created.

Example

13

Transaction Code

‘CMOD’

14

Create a Project

15

Enter the short text and select

Enhancement

assignment

from the menu or Application Tool Bar

16

Enter the Enhancement Name and save the project.

Note : at any particular point any enhancement can belong to only one Project

17

we will display customer no in sub screen area and display it using ME23 transaction

(screen shot taken from smod transaction)

This is where we will be

working with

18

• Points to be noted while coding• 1) the global data of the calling module pool is not known to the

function groups belonging to the subscreen.• 2) The function modules belonging to the program exists lie in the

same function group as the subscreen screen.

19

• PBO (main) PBO (sub)

• PAI (main) PAI (sub)

(YOU) Transfer the data to the subscreenCALL SUBSCREEN

Displays the data in

subscreen

(YOU) Transfer the data to the main program

CALL SUBSCREEN

Process the data received from the

subscreen

20

Go to SE51 and create a new subscreen

‘SAPLXM06’ with screen no ‘0101’

21

Just add the field EKKO-KUNNR and save it

To display the data here we will have to export the data in the main program to memory and then import it from memory into the subscreen

22

Go to SE51 and display the main screen

‘SAPMM06E’ with screen no ‘0101’

23

Here we have to code for transferring data to the subscreen for display

24

25

Double click on the user exit

EXIT_SAPMM06E_006

26

Double click on the include ‘ZXM06U36’

27

It will ask u to create a new object

Click ‘YES’

28

Write Your code here

i.e. export it to memory

Generate it and go back

29

Since I am trying to export EKKO-EBELN to I have declare this in the function pool which is of the same name as the subscreen I.e ‘SAPLXM06’

Go to se38 and give the program name as ‘SAPLXM06’ and display it

30

Since we are trying to declare the data double click on the include ‘LXM06TOP ’

31

Double click on the include ‘ZXM066TOP’

32

Now do your declaration here and generate it.

Once this part is done go back to the flow logic of your subscreen which you have created

33

Write your code in the PBO write a new module pool or use the existing

MODULE STATUS_0101.

(double click on the module

34

Type in your code here and generate

(i.e import your data here)

And go back to your flow logic

35

Generate your flow logic here

Go to your project and activate it
