Dear Experts,
I have added my custom tabs in QM01/QM02 using Customer Exit. Now need to add error message in QM01.
The scenario will be like this.
1. If user tries to create notification without putting batch number(custom field),system will through an error message and notification cannot be saved. Made this field as required but system is allowing to save the notification without this batch number.
2. If user tries to create a notification with the same batch number, system will through an error message, that already a notification was created and necessary measures was taken and the notification won't be saved.
Please tell me procedure to achieve this.
Thanks in advance.
Tania
