Hello and greeting to all.
I am trying to make an attribute called "SUPPORT ID", to be assigned to ONE attribute (computers), however, I do not want it to be possible to assign the SAME SUPPORT ID to more than 1 computer.
I'm running around in circles, any help would be greatly appreciated.
You need duplicate detection with CRM 4.
Even you can restrict using Callouts / Plugins to achieve this through code - see CRM SDK
