Im trying to create a new property on an Itemtype and when i make it unique it shows the following error any idea why?
Most probably you have Items in your database for this particular 'item type' where the property you are trying to mark as unique has duplicate values.
No actually this is a brand new property I created
Do you have some other property marked as unique on Item Type SubContract1?
Nopes there is none also I tried changing the name of the property as well but it would give the same error.
Can you share some screenshots? Like 1. filter properties which are unique2. Items grid of Subcontract1 to just have glimpse of data available
Are you trying to make the property from not unique to unique ? if yes, Is there any Subcontract1 item already created in system ? If yes, then set some unique value to those data and then try making this field to unique.
