Hello Venkatesh,

Please do the following while declaring your check-box:

PARAMETERS: cb_adw as CHECKBOX USER-COMMAND u-comm.

Please keep the rest of code same. This addition of USER-COMMAND u-comm will populate default values, when you check the checkbox, without a need to hit the ENTER button. Only thing to keep in mind, if you use USER-COMMAND, it should be the used on the first element on your selection screen (Check-box or radio-button).

Hope this solves your requirement.

Hi Venkatesh,

Try the 'User-command' addtion to your check box field.

This addition once implemented willt trigger the at selection screen output event when the checkbox is selected/deselected.

and then the code will be triggered.

Hope it was of help.

Hi Venkatesh,

I prefer to achieve this with Module Pool Programming.

ON INPUT and ON REQUEST will be helpful to achieve desired output.

... ON INPUT

Effect

With this condition, module mod is called only if the screen field dynp_field is not empty. All screen fields except fields of type STRING or SSTRING are considered empty if they contain nothing but blanks in the screen representation. Screen fields of type STRING and SSTRING are considered empty if they do not contain any characters.

... ON REQUEST

Effect

With this condition, module mod is called only if the value of the screen field dynp_field has been changed by input after the event PBO. It is considered as input if the existing input is overwritten with the same value or if the initial value of the field is entered explicitly. Besides user input, the following value input results in a call of mod:

I hope suggestion will be helpful to achieve your requirement.
