The hradmin approval decision table can be defined as follows:

The screenshot also shows sample data, matching your original requirements.

You can download the .dmn example here: https://kiegroup.github.io/kogito-online/?file=https://gist.githubusercontent.com/tarilabs/f9655e2f8a2c4253e66ce661e5c79879/raw/so69764028.dmn#/editor/dmn

  • I'm noticing only now, the question has a tag of specific vendor, but not clear if it's related to any vendor-specific features. The answer I provided anyway is purely DMN based, so it should work the same or analogously on any DMN-enabled platform. Hope that helps anyway! – tarilabs Oct 29 '21 at 16:33

You can save the xml to a text file, upload it, try it out and modify it here: https://consulting.camunda.com/dmn-simulator/
