Thanks for immediate response.
Will you provide the codes in exit for notification.
System should not allow user to complete the notification if order is assigned to notification and should
allow if order system status is TECO.
And without checking TECO it has been now working as i have created one user status CLSD and attached business transactions.
Once user status selected as CLSD then system allow to do NOCO. For all other user status set forbidden.
Thanks and Regards
