syntax error in screen

hello all,

i have a custom table for which i generated table maintenance dialog. its fine in Dev. system. when i transported it to Quality, the request had import error saying the screen has error.

particularly error is 'field PROCESS BEFORE OUTPUT' has length zero.

as a way around, second time, i deleted the table maintenance, transported deletion. in Quality table maintenance is correctly deleted. i ,then,created table maintenance in Dev. system afresh and transported it to Quality hoping that it would be fine this time.

but still i have same import error.

can anyone pls help me !

points are guaranteed for useful answers.

thanks !
