Afaik the limit values refer to the corresponding dlp policy/rule object, which you can get via PowerShell. Most likely the XML representation, which you can also get via the "export" functionality: https://learn.microsoft.com/en-us/purview/purview-policy-export

Thanks VasilMichev

I have exported one policy and extracted it and checked the size of the policy it shows 346KB, where in Microsoft says limit is 100Kb, it is kind of contradictory. Please let me know what is the best way to determine the limitation, it is very important else we cannot make the decision to include more rules in the policy.
