While importing the data from iBilling, any contacts with email address is blank is not getting imported.
When i put a dummy email address instead of blank, all contacts imported.
All the services in iBilling is now showing the same attributes of products like Cost Price, Inventory, etc
Staff/Users are not imported
Roles are not imported
After manually creating the roles (i created Employee & Auditor) and Staff same as that in ibilling, Now the Staff cannot see any transaction. But if a staff was given Full Administrator rights, Staff can see everything. That means Roles is not functioning as same in ibilling.
