Quick Map Reduce Script to do the Work of a User Event Script 

Very often, when working with SuiteScript, a developer will be tasked to write a map-reduce script that updates all of the NetSuite records that their user event script is already updating. If this is the case, a minimal map/reduce script can be written to put all the work on the user event script. This method also has the benefit of decreasing the amount of code that may have to be reworked to just the user event script.

Setting Up the Map/Reduce Script

Step 1: Check that your user event script is set to trigger on the map/reduce context.

Step 2: In the getInputData stage of your map reduce, return a search for the NetSuite records you wish to update in the map reduce. Below is an example:

        return search.create({
            type: "commercecategory",
            filters: [],
            columns: [
                search.createColumn({
                    name: "internalid",
                    sort: search.Sort.ASC,
                    label: "Internal ID"
                })
            ]
        });

Step 3: In the reduce script, load and save your NetSuite record, triggering the user event script on record save. Use the reduce context’s key to get the NetSuite record’s internal ID, and do not forget to put everything around a try/catch block to catch errors that may occur. Here is an example of how the reduce code would look:

    function reduce(reduceContext) {
        try {
            record.load({
                type: record.Type.COMMERCE_CATEGORY,
                id: reduceContext.key
            }).save({ignoreMandatoryFields: true});
        }
        catch (e) {
            log.debug("reduce error", e);
        }
    }
