Dynamic selection

[Former Member]

Hi Experts,

I was going through dynamic selection screen and have come across following code.

Please explain the role the following coding will do.

IF r_local = 'X'.

LOOP AT SCREEN.

IF "screen-name = 'P_LOCAL'. "OR

screen-name = '%_P_LOCAL_%_APP_%-TEXT'.

screen-invisible = '0'.

screen-input = '1'.

MODIFY SCREEN.

ELSEIF screen-name = 'P_SERVER'. " OR

screen-name = '%_P_SERVER_%_APP_%-TEXT'.

screen-invisible = '1'.

screen-input = '0'.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

• Server

ELSE.

LOOP AT SCREEN.

IF screen-name = 'P_SERVER' OR

screen-name = '%_P_SERVER_%_APP_%-TEXT'.

screen-invisible = '0'.

screen-input = '0'.

MODIFY SCREEN.

ELSEIF screen-name = 'P_LOCAL' OR

screen-name = '%_P_LOCAL_%_APP_%-TEXT' OR

screen-name = '%_S_KUNNR_%_APP_%-TEXT' OR

screen-name = '%_S_KUNNR_%_APP_%-OPTI_PUSH' OR

screen-name = 'S_KUNNR-LOW' OR

screen-name = '%_S_KUNNR_%_APP_%-TO_TEXT' OR

screen-name = 'S_KUNNR-HIGH' OR

screen-name = '%_S_KUNNR_%_APP_%-VALU_PUSH'. .

screen-invisible = '1'.

screen-input = '0'.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

ENDIF.

Hi,

This code is used to modify the screen fields ie make it invisible or visible during run time as it is a dynamic selection screen.

if r_local = 'X'.

then the parameter 'P_LOCAL' will be displayed.

else.

'P_SERVER' will be displayed.

'P_LOCAL' will be invisible

endif.

hope it helps.

screen-name = 'P_LOCAL'. "OR

screen-name = '%_P_LOCAL_%_APP_%-TEXT'.

in module pool when creating i/o field ..u will be giving name to the i/o field..

goto se51 put ur program name and put screen no 1000..

there u goto layout and click the i/o fiald and see the attributes ur screen name will be like this screen-name = '%_P_LOCAL_%_APP_%-TEXT' it is generated by system.

Hi,

.

screen-name = 'P_LOCAL'. "-------------------------> name of the label in    selection screen
OR screen-name = '%_P_LOCAL_%_APP_%-TEXT'.---------------------> name of the text field next to the label.....

just put a break-point under LOOP AT SCREEN..it will be clear

Hi Nani,

Loop at Screen Statement is basically used to putting aloop on the screen fields whichare present on the screen ( It can be a selection screen for your case).

While using the Loop at screen you are assigning the value to the screen fields to execute further.
