Module pool

Former Member — Thu, 14 Aug 2008 07:35:09 GMT

Hi all,

I have to develop one module pool program which will have two screens.The first screen is for selecting data and the second screen is for create,change and display data using table control.I have to create three transactions to maintain the custom table.One transaction is for creating entry in the custom table,One transaction is for changing entry in the custom table,One transaction is for displaying entry in the custom table.

In case of creating entry the transaction will hit the second screen directly.In the second screen the user will create entry and save the entry and that will update the custom table.

In case of change entry the transaction will hit the first screen.In this screen the user enter valid data and hit the enter button.Then the second screen will be opened in editable mode.Then the user will make the changes and will save it.

In case of display entry the transaction will hit the first screen.In this screen the user enter valid data and hit the enter button.Then the second screen will be opened in display mode.the user will can only view the fields.

Can any one suggest how to do this development?

Waiting for your replies.

Regards

Raj

Hi....

Create two screens...

First screen with DISPLAY, CREATE, CHANGE pushbuttons and if you want arrange some input parameters.

Second screen with one table control, and ENTER push button.

Now..,

>To Display entries..,

1. Run transcation.

2. Give input parameter and click on DISPLAY.

3. you can get 2 nd sreen with entries,

>To Create entries..,

1. Run transcation.

2. Give input parameter and click on CREATE.

3. you can get 2 nd sreen with empty table control,

4. Enter the records, click on SAVE

>To Chage entries..,

1. Run transcation.

2. Give input parameter and click on CHANGE.

3. you can get 2 nd sreen table control entries,

4. Modify the records, click on SAVE

This is Better...

Try like this,

Search forums on this concept...

Get back if you need any further logic...

Thanks,

Hi Raj ,

For the module pool you are planning to do , follow this proces :

1> Create a module pool program and design the 2 required screens along with the logic .

2> Create mode : create a transaction ( Ex: Z_create ) and provide the screen number of the 2nd screen .

( As you need to directly make entries in 2nd screen) . In the flow logic of the 2nd screen , write the logic for saving these recently entered values in the DB ).

3> EDIT amd DISPLAY MODE : create 2 separate transactions for EDIT and DISPLAY modes , and give the 1st screen number in the initial screen field and even provide the module pool program name .And then Based on the operation call the 2nd screen when needed .

4> Based on the transaction , make the required fields editable ( for Edit mode ) and non editable ( for Display mode ) write the corresponding logic for these in both the screens .

The above logic is a very generic logic for creating transactions in 3 modes .

Reply if any fuether help needed ..

Ranjita

hi,

we will see the scenario one by one..

let the 2 screens be 100 and 101.

Now,let the Ok-codes be CHAN,DISP,CRET for change,display,create resp.

the code will be as follows to call the resp. screens.

Case sy-ucomm.

when 'CHAN'.

call screen 100.

(now you can write your code in that screens)

when 'DISP'.

call screen 100.

when 'CRET'.

call screen 101.

endcase.

Now you will also have to modify the attributes of the screen like when you want to change the fields that you require to change should be editable and incase of display all the fields should be non-editable.

Hope this helps.

if you need more information feel free to ask.

Thanks,

Rashmi.

Hi,

U can do so my creating a module pool program with two screens, say 1000, 2000

On one screen jus give the required fields and on the other make the table control.

Now create three transactions say 'CREATE', 'CHANGE', 'DISPLAY'.

Now write the following logic in the PBO of the first screen.

case sy-tcode.

when 'CREATE'.

CALL SCREEN 2000.

when 'CHANGE'.

CALL SCREEN 1000.

when 'DISPLAY'.

CALL SCREEN 1000.

ENDCASE.

for keeping the fields in the display mode when display transaction is run u need to write the following code in the PBO of the first screen.

WHEN 'DISPLAY'.

LOOP AT SCREEN.

IF screen-name CS ' wa_EKKO'.

screen-input = 0.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

where wa_ekko will be the work area assigned to the respective fields.
