At selection screen event is trigerred at a particular happening , ie for data validation only , and hence it can be used only once.

Hi,

Try out more things using a Test system as it would be more useful and you will learn more, rather than getting answers by posting those queries.

Hi,

Try writing the code twice.

If you want to validate use once at selection-screen and multiple at selection-screen on value-request for<fields on the selection scree>.

Thanks,

Hi Praveena ,

I dont think you can call the event 2 times , as the event is triggred by the system.

If you can tell the scenario in which you want this to happen may be we can suggest an alternative to it.

Arun

Hi Praveena

i think there is a possibility that is

by using AT SELECTION SCREEN ON <FIELD_NAME>

AND, AT SELECTION SCREE OUTPUT

IN THIS WAY WE CAN USE IT TWICE.

try this and let me know.

best regards

Hi Praveena ,

The control will go to the event and not the code you added in the enhancement . I think you have used implicit enhancement , so may be you can try using AT SELECTION-SCREEN ON <field name> event .

In the enhancement use the AT SELECTION-SCREEN ON event and put your authorization / validation code in it.

Arun

Hi Praveena ,

Please see the code below

at selection-screen on emplck.
   if emplck = 'X'.
  MESSAGE E000(SR) WITH 'You are not authorized person'.
  endif..

If i understand your requirement correclty when the user selects any of the check boxes other than Employee

like Centeral Person system must generate an error .

So it means that no one must be able to use the transaction selecting that checkbox.

Arun

Hi arun..

Thanks a lot..

now error mesg is coming...ZMSG:000 you are not authorized..i need to display only you are not authorized and one more thing is i am not able to re edit screen...can you plz tell me

Re: At selection screen event

Former Member — Wed, 24 Nov 2010 07:26:57 GMT

Hi Praveena ,

You need to know the authorization object and use the FM to check if the user has authorization for it or not.

Regarding the issue of not being able to edit the screen you will have to debugg the report , as i see some code to enable and disable the screen elements in the report.

Regards

Arun

This is a prime example of drip-feeding a question. If you'd posted your actual requirement straight off, you would have got your answer much more quickly, and you wouldn't have wasted moderator time looking at what appeared to be a very basic, easily researched question.
