HI

How to validate a field in selection-screen of a dialog program.

hai,

you have to write the validation code in the PAI event.

Ex:

PROCESS AFTER INPUT.

FIELD <fname> MODULE validate_<fname>.

then you can write ur validation code in the module.

AT SELECTION SCREEN OUTPUT.

MIGHT ALSO BE HELPFUL

Hi,

In the PAI event,

CHAIN

Field : l_empid validate_empid.

field : v_name validate_name.

ENDCHAIN.

Create form/endform of validate_empid. It will be called automatically and validation would be done.

Hi

Validations should be done in Process After Input.

In PAI, use chain and endchain for validation of fields.

hI,

For the validation of a single field u have to use the syntax in PAI

FIELD <fieldname> MODULE <modulename>.

and for more than one field u can write the code between Chain and Endchain.

Hope this helps u.

hi,

The validation of a single field

In PAI, you have to mention the field and do the validation in corresponding module.

FIELD <fieldname> MODULE <modulename>.

if you want to validate more than one field then you need to write in Chain and Endchain.

Hope this information is useful.

use at selection-screen on <fld_name> in the PAI of the calling screen.
