[MDS] use business rule to set 2 attribute as composite and must be unique on one entity

Hi All,

As title, I have an entity which include 3 attributes (COMPANY, TEAM, COUNT) as below,

------------------------------------------------------

------------------------------------------------------

And I know business rule can set action for unique check, but what I want is to checkCOMPANY+TEAM should be unique, not just one attribute check.

Please advise if any solution, thanks in advanced.

BR,

Jackie
