Hi,

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

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

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
