Input field is disabled on error
I am facing problem with respect to an input field that is designed in screen.
Screen has 1 input field and below the input field is container to display ALV grid.
when ever i get error on the screen due to some other validations i put based on Application tool bar icons this input field is being disabled, even though i have chain endchain for this inputfield.
Appreciate if someone can help me out in how to enable the input field back.
PROCESS BEFORE OUTPUT. MODULE PBO_100. CHAIN. FIELD ZTEIHDR-ACCT_PAY_OFR_NAM MODULE CHECK_ACCT_PAY. ENDCHAIN. PROCESS AFTER INPUT. MODULE PAI_USER_COMMAND_100.
