Hi,

Write your validation code in the event

At Selection Screen ON (PARAMETER OR SELECT OPTION VARIABLE NAME Eg: s_matnr).

i am doing some modification to a pre existing screen. the validations for some of the fields already existed, and i have added my code with them(in an include program), but when i get an error all the fiels become uneditable. Where can i find this event mentioned below?

Hi,

I guess you are talking about Module pool programming,

    CHAIN.
    FIELD ZMATNR.
    FIELD ZKTMNG.
    MODULE GT_ITAB1_MOD.
    ENDCHAIN.

Write the field names of those that you want to make uneditable using the FIELD statement.

Hi Kumar,

I assume you are talking about module pool screen.

You have to use validation in PAI as follows:

CHAIN.

FIELD input3.

FIELD input4.

FIELD input5.

MODULE check_chain ON CHAIN-REQUEST.

ENDCHAIN.

So whenever one of the fields (input3 , input4 or input5) is having error data, all 3 fields will available for input.

yes there is an existing code as you have mentioned, i will have to add the field name only to the existing list.

THanks a lot to everyone.

How do i change the PAI?

The include program in which i can see the "chain - endchain" command while debugging, does not contain the chain oprator when i see the code in se38..
