Updating Priority based on Business Rule on creation from 3rd Party system

[Community Alums]

Hi Team,

We have to set priority using 3rd part integration based on  category and subcategory but its not working. 

I have written below BR Before Insert

(function executeRule(current, previous /*null when async*/ ) {

    // Add your code here

    // var Priority=1;

    var categoryCritical = [68, 70, 71, 72];

    var subcategoryCritical = [583, 595, 596, 597, 575, 581, 536];

    var categoryModerate = [70, 71];

    var subcategoryModerate = [598, 2052, 576, 582, 572, 574];

    var categoryLow = [71];

    var subcategoryLow = [577, 578, 579];

    var categoryHigh = [72];

    var subcategoryHigh = [535];

    var cat = current.getValue('category');

    var subcat = current.getValue('subcategory');

    if (categoryCritical.indexOf(cat) == -1 && subcategoryCritical.indexOf(subcat) == -1) {

gs.info('critical');

        current.priority=1;

    }  if (categoryModerate.indexOf(cat) == -1 && subcategoryModerate.indexOf(subcat) == -1) {

        gs.info('Moderate');

        current.priority=3;

    } if (categoryLow.indexOf(cat) == -1 && subcategoryLow.indexOf(subcat) == -1) {

gs.info('Low1');

        current.priority=4;

    } if (categoryHigh.indexOf(cat) == -1 && subcategoryHigh.indexOf(subcat) == -1) {

        gs.info('High');

        current.priority=2;

    }

})(current, previous);
