can pai trigger without pressing enter

[Former Member]

i have created a module pool program.

when user enter some value in text field..then after pressing enter pai triggeres and description corresponding to that value from ztable is shown in another output only field.

could it be possible that without pressing enter just after value entered...corresponding desc will be fetched in output only field.

if have also used fm.

F4IF_INT_TABLE_VALUE_REQUEST

on event process on value request.

can we define multiple return field in this function module?

Hi,

No it wont trigger automatically .

Instead you can use screen programming & handle CHAIN-END CHAIN in PAI of the screen. This will work.

I have used CHAIN ENDCHAIN STATEMENTS. but they wont trigger untill user press enter.

the big problem is this:

if user does not press enter--the description will not be fetched and smartform will be printed without descriptions.

what about multiple return fields in FM.???

What you can do is fetch description in smartform only if this is the case.

Hi,

Sorry for misleading... actually with the buttons it works.

Check in the user command (If you have any button (action ) for calling smartform) . here the values will be filled. you can fill the description also here

What exactly you mean by "what about multiple return fields in FM.???"

If you are expecting Multiple values from the return table. YES it returns Multiple values

Here is my COde:

data :begin of i_dept occurs 0,
kostl like cskt-kostl,
LTEXT like cskt-LTEXT,
end of i_dept.

how to declare multiple return fields in this parameter of function module.????

       DYNPFLD_MAPPING        =

i have used POV on a textfield. amd i m calling this function module in POV.

what i want:

when user click on kostl of i_dept( in the help displayed)..then along with field KOSTL....LTEXT field also returns in

screen field ZRETURN_GP-GOING_TO_DEPT_DESC.

I Have read in the documentation of this function module that in parameter

• DYNPFLD_MAPPING =

we can declare multiple return fields.

thats is what i want to know....how to declare multiple return fields.???

suggest some methods.

new concepts are also welcome.!

Hi,

could it be possible that without pressing enter just after value entered...corresponding desc will be fetched in output only field.

You cannot assign a function code to input text fields, therefore this is not possible...

In order to have your description updated in your smartform (or whatever), the module used to fetch the texts should be placed before your module dealing with user commands.

can we define multiple return field in this function module?

What you can do is, based on your returned fields, update some others with the FM DYNP_VALUES_UPDATE...

Kr,

Manu.

added: you could also use a callback routine, as described in this thread:

been a while since I've tried this but consider adding this in your PAI.

FIELD fieldname MODULE modulename ON INPUT.

[surajarafath]

One thing we can do is, to press the enter key function explicitly by using this code..

CALL FUNCTION 'SAPGUI_SET_FUNCTIONCODE'
   EXPORTING
     FUNCTIONCODE                 = '=ENT'
   EXCEPTIONS
     FUNCTION_NOT_SUPPORTED       = 1
     OTHERS                       = 2.

then PAI Can be Triggered...
