Hi All,
Today I will cover where all you can call Decision table in ServiceNow.
1. You can call decision table in Flows by calling the "Make a Decision" OOB action. See below:
Based on the number of results in Decision table you will get the same branches in Flow when you use the Make a decision in Flow Designer. So, if there are 3 results in Decision table then you will see 3 branches in Flow Designer automatically generated by the system as soon as you click Make Decision Action in Flow.
Example, I have a Maternity Leave application which has the logic of having the number of days against each country saved in Decision table hence I have 3 entries as shown below:
Flow Designer:
Now, based on my 3 entries in Decision System has generated 3 branches in Flow. Shown below:
Note: Make sure your decision table is published in order to select that decision in Flow and reflect the same number of branches.
2. We can call decision table from any Server-Side Script as well. See below:
try{
var inputs={};
inputs['u_locations'] = ; // Choice
var dt = new sn_dt.DecisionTableAPI();
var response = dt.getDecisions('c0ac7cf5c36012103478be3ed4013121', inputs);
for (var i = 0; i < (response && response.length); i++){
var result = response[i];
var result_elements = result.result_elements;
var u_date_calculations = result_elements.u_date_calculations.getValue(); // String
}
}
catch(e){
gs.log("Couldn't run this script Error: "+e)
}
