I'm new to nintex workflow so forgive me. I have a project that i'm working on and need some help. I have created a Nintex form and workflow used to populate a Sharepoint 2010 list with delivery schedules. I have the form creating the following items in the list
Delivery Door : Status: Sceduled Date: Carrier:
I need to be able to find a way to not allow duplicate items to be created in the list for the same door at the same time.
I.E. I cant have Door 01 booked at 4:00 PM by 2 different deliveries.
The other part I am struggling with is, after the form is filed out and save is selected. I need to have a pop up message that will display and error message if a duplicate scedule has been found and stop the workflow and return to the form so the user can select a different date, time or door.
Any help would be greatly appreciated
Thanks
Ron
