Hi,

You can have the screen in editable mode only if you are doing your validations in CHAIN ..ENDCHAIN.

Hi,

while creating the screen ,you need to write the logic in PAI.

PROCESS AFTER INPUT.

CHAIN.

FIELD : field1,

field2.

MODULE field1.

MODULE field2.

ENDCHAIN.

if you write the code like,it will give error message but all fields are editable

shall i write my validations within chain and endchain?

For ex;

CHAIN

if ( ( sy-tcode = 'ME21' or sy-tcode = 'ME21N' or sy-tcode = 'ME22' or sy-tcode = 'ME22N' )

and i_ekko-bsart = 'nb' ).

if ( i_ekpo-mtart = 'roh' or i_ekpo-mtart = 'halb' or

i_ekpo-mtart = 'fert' or i_ekpo-mtart = 'fhmi' or

i_ekpo-mtart = 'hawa' ).

message E000(ZNB) WITH i_ekpo-mtart.

else.

ENDCHAIN
