Then I am doing concatenate 4 fileds data into the 5th field in the event AT SELECTION-SCREEN OUTPUT, but my problem is When ever i click ENTER , then only 5th field is updating. With out ENTER key , Is it possible update 5th filed.

Thanks,

hi,

there has to be an event to update the 5th field which is ENTER here...

i dnt think without any event triggering it you can update the 5ht field since the control has 2 flow frm screen to code and back 2 code...

Hi Kiran,

ABAP is event driven programming language but unlike other event driven languages it has a set of events that are fired and unfortunately events like lost focus or got focus are not among them so any operation you need will happen only if an event which exists in ABAP will fire and in your case hitting enter is probably the best scenario.

Sachin

Hi Kiran ,

Try doing the concatenation in the INITIALIZATION event then you might get it !

Hi ,

If want to update the 5th field with out ENTER you can use two Radiobutton as follows -

PARAMETERS : p1 RADIOBUTTON GROUP rgp USER-COMMAND ONLI DEFAULT 'X',

p2 RADIOBUTTON GROUP rgp .

After filling the first 4 fields you can swap the radio button to get the fifth field populated .

Hi,

We can restrict the functionality of ENTER.

User the Concatenation in AT SELECTION-SCREEN EVENT

because AT SELECTION-SCREEN OUTPUT is triggered before

selection screen is displayed.Below code will definitly work.

Ex:

Tables:SSCRFIELDS.

At selection-screen.

IF SY-ucomm = ' '.

Clear SSCRFIELDS-UCOMM.

ENDIF.

CHECK SSCRFIELDS-UCOMM EQ 'ONLI'.

CONCATENATE <FIELDS> INTO PARAMETER5.

ONLI is Function code of F8

' ' is for enter.

The above code will surely work.

Thanks.

Hi Kiran,

There's no such event in ABAP that can automatically assign concatenated values of the above given parameters without hitting ENTER KEY.

Had it been radiobutton, it can be automatically done by assigning USER-COMMAND.

Thanks.

PARAMETERS : p1 RADIOBUTTON GROUP rgp USER-COMMAND ONLI DEFAULT 'X',

p2 RADIOBUTTON GROUP rgp .

i dont need the second button. But when i am using one button it is giving me error message that 'the RGP contains only one parameter'. I dont need the second one. or if it is there, when i click the P2 button the field should be errased, can we do that.

Thanks to all especially for Gurpreet Singh and Tanveer Zahack.

Kiran.

Hi,

P1 and P2 are radiobuttons, you can not have a single radiobutton, thats why you receive the error message. You can code such that when p2 is selected parameters will clear.

Simplely write

if p1 = 'X'.

do the concatenate fucntion

else.

clear: parameter list.(5 parameters u have created)

endif.

Hope this helps

Sachin
