how to pass parameter from user event to map reduce and how to read that parameter in map reduce

AI generated answer (using internal Slack threads):

To pass a parameter from a User Event to a Map/Reduce script, you can use the script deployment parameters. Here's how you can do it: 1. In your User Event script, set the value of the script parameter for the Map/Reduce script. You can use the

N/task

module's

submit

method to do this. 2. In your Map/Reduce script, you can read the parameter value using

runtime.getCurrentScript().getParameter({name: 'custscript_your_parameter'})

. Here's a sample code snippet: User Event Script:

javascript
var mrTask = task.create({taskType: task.TaskType.MAP_REDUCE});
mrTask.scriptId = 'customscript_your_mr_script';
mrTask.deploymentId = 'customdeploy_your_mr_script';
mrTask.params = {
    'custscript_your_parameter': 'your_value'
};
var mrTaskId = mrTask.submit();

Map/Reduce Script:

javascript
var scriptObj = runtime.getCurrentScript();
var paramValue = scriptObj.getParameter({name: 'custscript_your_parameter'});

To pass data to the summary function in a Map/Reduce script, you can use the

context.write

method in the map or reduce stage, and then read it using

context.output

in the summary stage. Here's a sample code snippet:

javascript
function map(context) {
    // Write data to be passed to the summary stage
    context.write({
        key: 'your_key',
        value: 'your_value'
    });
}

function summarize(context) {
    // Read data passed from the map or reduce stage
    context.output.iterator().each(function (key, value) {
        log.debug('Key', key);
        log.debug('Value', value);
        return true;
    });
}
