DMN Unique Policy Error DMN-03001

This is a simple DMN with the following inputs and outputs
[0…5] → “Less than”
[6…8] → “Range”
[9…15] → “Greater than”

• → “Gulbarga”
  When i execute this rule with a value of “0”, it results in a UNIQUE policy violation, shouldn’t it match the first rule only?

Got the answer here in this thread,

DMN Unique Policy Default erro

Hi @GremlinAtTheDisco Welcome to the forum. You said: Sadly this is not the case. The unique hit policy can’t ever have a default as part of the table because it will always match another field and so 2 results will be returned. If you want a default you’ll need to use the first hit policy.
