Hi TArun,

In PAI if you want to validate group of fields put in

chain and End chain statement .

You can declare fields in the chain enchain .

CHAIN.
FIELD chk_ABC.
FIELD chk_DEF.
FIELD chk_GHI.
FIELD CHK-JKL.
MODULE CHK_screenfields.
ENDCHAIN.


MODULE CHK_screenfields INPUT.
CLEAR okcode.
okcode = sy-ucomm.
CASE okcode.
WHEN 'ENTER' OR 'EXECUTE'.
 
IF chk_ABC IS INITIAL AND chk_DEF  IS INITIAL AND CHK_GHI 
IS INITIAL .
MESSAGE e000(zo_spa) WITH text-017. " Enter VALUES'
ELSE.
  .....
ENDIF.
ENDIF.
 
ENDMODULE. " modify_screenfields INPUT

Check the Below Demo Programs.

demo_dynpro_automatic_checks

Hi

Using FIELD Statement in the Flow Logic we can validate a field in the Module Pool Programming.

Eg. FIELD <fieldname> MODULE <module_name>.

Hope this would help you.

Hi.....

If you want to validate a perticuler field and display erroir message if user enters wrong input...

Do like this....

say P_F1 is field attribute name.... in layout...,

Now write this syntax for the next actions in that screen after enters the input into that field...in PAI event

Decalere itab with that field...

> select * from <check table of that field> into correspoding fields of tabel itab where F1 = P_F1.

>

> If sy-subrc <> 0

> message 'P_F1 does not exists' type 'E'.

> Endif.

>

We can do field validation like this also...in module pools..
