A Disjunction operation can either have comparisons and ranges. Test returns true if one of the condition is true at a time otherwise it return false if all the conditions in a Disjunction expression are false.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Examples:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">  2,15,71: Test if the input is either 2, 15 or 71<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"> <5,>10: Test if the input is either less than 5 or greater than 10<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"> 1,[14..30]: Test if the input is either 1 or between 14 and 30<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"> \u201cApple\u201d,\u201dSamsung\u201d,\u201dRedmi\u201d: Test if the input is either the String Apple, Samsung or Redmi.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">4. <strong>Negation<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Negation means invert the output of a Boolean expression given in DMN Table. In Feel a unary test can be negated with not operator. A Negation can work on a Single expression, range and comparisons. It can\u2019t be used with a combination of Disjunction expression.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Examples<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">not(\u201cProvider\u201d): Test if the input is not the String Provider<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">not(>10): Test if the input is not greater than 10, which means it is less than or equal to 10<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">not(3,5,7): Test if the input is neither 3, 5 nor 7<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">not([20..30]): Test if the input is not between 20 and 30<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">not([0..17]),>0 can\u2019t use Negation with combination of Disjunction Expression. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">5. <strong>Date Functions<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Camunda DMN Engine support below date function to convert a String to Date and Time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">date and time(\u201c\u2026\u201d): Creates a date and time value from a String with the format yyyy-MM-dd\u2019T\u2019HH:mm:ss<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Examples:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">date and time(\u201c2015-11-30T12:00:00\u201d): Test if the input is the date November 30th, 2015 at 12:00:00 o\u2019clock<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">2.5 <strong>DMN Hit Policy<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A decision table has a hit policy that specifies what should be the results of the evaluation of a decision table consist of. The hit policy is set in the hitPolicy attribute on the decisionTable XML element. If no hit policy is set in the hitPolicy attribute of decision table, then the default hit policy Unique is used.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">\u00a0<strong>Types of Hit Policies<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\" type=\"1\"><li><strong>Unique Hit Policy :<\/strong> According to this policy only a single rule can be satisfied at a time or no rule at all.

If an aggregator is used with collection hit policy then it returns only a single result based on the aggregator used. There are four types of aggregators supported by Camunda\u00a0 DMN Engine.<\/p>\n\n\n\n<ol class=\"wp-block-list\" type=\"1\"><li><strong>Sum Aggregator:<\/strong> This Aggregator can be used to sum up all the outputs from the satisfied rules.
