hi,

-the code should be in PBO, not in PAI

-you also have to press Enter, adding the value to the first field won't be enough

hope this helps

Hi,

is there any way so that we can trigger the PAI of the screen...

by giving F4 help manually to the First Screen in the POV ...

Thanks,

If this is a program then it's easy

BEFORE the START OF SELECTION

at selection screen output
* check field entered
* update your 2nd screen field  directly.

If you need to use a HELP like F4

at selection-screen on value-request for  screen-field
* your help code
* update with call to (FM DYNP_VALUES_UPDATE updates screen fields WITHOUT a PBO).

Code these before the start-of-selection if running an ABAP..

If you are in a transaction / sequence of screens then use the ON VALUE REQUEST in the screen logic to trigger your help code.

code

Call to the same Function module will update the appropriate dynpro fields without a PBO.

Hi,

To handle the EVENT you should perform some event action,

in that scenario pressing ENTER key(any button...etc) is also an event.

So when u press enter the sy-ucomm will be space, so that u can handle the logic with in PAI.

In user-command module write as below.

case sy-ucomm.

when SPACE.

--> P_FIELD2 = <your calculated value>

endcase.

Hi,

As you know for an event to happen there is need of user interaction ,

User interaction with the screen is done through FCT codes

there must be Some user interaction like pressing an ENTER key for an event to happen

In the PAI under case sy-ucomm write the code you require

ENTER KEY has FCT code /00 or '=ENTR' ( not sure but you can try)

Hi Bharathi,

For my Sense, What u have made to block your code in PAI is right....

But..

I have two suggestions for this...

1) aftering entering values in the first field have to press some button or ENTER for an action.. So that the Second field can be make populated based on that...

2) If the First field CAN BE a set of repeated Values , you can maintain it as DROP DOWN - LIST, so that you have an action triggered for the item selected in the list.

Hi Bharathi,

You can achieve ur target even with the following process:

If the fieldnames are f1 and f2. Now upto my understannding what you need is f2 values should change according to the values selected in the field f1.

Initially keep the second field f2 disable and make it enable only when the user selects a value for f1.

All the logic should be in the PBO module.

LOOP at SCREEN.

if screen-field = f1 .

"Check whether the user has entered value in field f1 or not

" if yes make the field f2 enable

"else throw some error message

" now write the required logic or select query

endif.

ENDSCREEN.

Hope it will helps you.

Hi Bharathi,

Write the Logic in PAI.

There should be one action event to perform the action .

so when user press enter sy-ucomm will be space . So that it wl execute the action in PAI.

case sy-ucomm.

when SPACE.

call BAPI.

endcase.
