I have created custom screen in purchase document item (ME21N) using Exit MM06E005.
i have used the function module EXIT_SAPMM06E_016 & EXIT_SAPMM06E_018 and screen 111.
i placed only one field in my screen namely EXPO_CI-STLAL.
i had validate this field using BADI ME_PROCESS_PO_CUST and method CHECK init.
as check method is not supported warning message i had raise message using MACRO as per following syntax
MMPUR_MESSAGE_FORCED 'W' 'ME' '303' MESSAGE '' '' ''.
now this will open popup of list of warning message and working fine,but when i select my message and press edit button cursor is not set on custom field.
Hope You understand the problem.

For Example i am getting following list of message,in this, first message is my custom message and when i select this and press edit button cursor is not set on my custom field.
