handling an event in dialog..

[Former Member]

hi,

i have a screen with a tabstrip inside which a subscreen exists. in that subscreen i have two fields in which user can enter/choose any value. Once he does that it's corresponding value i need to fetch from the table and display in a nearby display only text field.

so in the PAI of the subscreen i need to write the logic that will identify when the user modifies the value in those fields and then fetch the equivalent value for the display fields.

what is that logic ?

my guess is something like

PROCESS AFTER INPUT.

LOOP at SCREEN.

??

??

ENDLOOP.

I am not sure what to write. any help ?

even if you write some thing in pai it will not work.

"this is wrong...
PROCESS AFTER INPUT.

LOOP at SCREEN.
??
??
ENDLOOP.

you have to call the function DYNP_VALUES_UPDATE in the event PAI ,say when ENTER Action.

u can use 'ON CHANE OF <field_name>'

actually i used

FIELD <fieldname> module <module name> and it worked...

but one problem is that in a situation i need to blank out that display field. if i simply say MOVE ' ' TO f1. it does not help...how do i inform SAP to refresh the screen so that the display field now displays blank ?

thks

why can't you update the screen field value using the function module DYNP_VALUES_UPDATE

hey vijay,

i used the FM u said. thanks...but i am facing an issue where in my subscreen there are two display fields that i need to clear out based on two fields...so my PAI has statements as

FIELD F1 MODULE F1_VALIDATE.

FIELD F2 MODULE F2_VALIDATE.

Now it so happens that in F1_validate and F2_validate I have written code as follows

SELECT SINGLE PORT_NAME INTO L_PORTNAME FROM ZTAB WHERE PORT_CODE = F1.

CLEAR WA_DYNPREAD.

REFRESH I_DYN_FIELDS.

WA_DYNPREAD-FIELDNAME = 'F1_DISPLAY_FIELD'.

WA_DYNPREAD-FIELDVALUE = L_PORTNAME .

APPEND WA_DYNPREAD TO I_DYN_FIELDS.

CALL FUNCTION 'DYNP_VALUES_UPDATE'

EXPORTING

dyname = SY-REPID

dynumb = SY-DYNNR

TABLES

dynpfields = I_DYN_FIELDS

EXCEPTIONS

INVALID_ABAPWORKAREA = 1

INVALID_DYNPROFIELD = 2

INVALID_DYNPRONAME = 3

INVALID_DYNPRONUMMER = 4

INVALID_REQUEST = 5

NO_FIELDDESCRIPTION = 6

UNDEFIND_ERROR = 7

OTHERS = 8.

what happens is the display fields are updated only after my second field's validation is done !!

i want this way..as soon as user presses enter key to move out of the first field i want the f1_display_field to have the display value...same with second field..whats wrong ?

thsk

[former_member188685]

are you writing this in PAI user_command module or placing in the respective field modules..?

[Former Member]

field modules...

[former_member188685]

then it should trigger before the enter event. since field modules will trigger for each change in the fields.
