In Decision rule table, if there is more than one input column then only AND condition is possible? is anyway we can do OR also. Please help on this.
This is how DMN Decision Table rules work as defined in the spec; a rule is considered valid when all expressions resolve true.
There is no option to configure that ‘when any of the expressions resolve true’ should be applied.
You should either separate the ‘OR expressions / conditions’ in to multiple rules.
Or create a custom (OR) expression.
