Hi,
I have a customization in ERPNext 14 to check for duplicate customer registrations.
When a duplicate customer is detected during registration, a warning should be displayed along with a list of duplicate customer IDs.
In my case, I am using an approval workflow. When the Approve button is clicked, I need to validate for duplicates, display the list of duplicate customers, and prevent the workflow from proceeding. The workflow should remain stopped until the user manually triggers a button in my dialog box or message box.
