Hello,

I am currently struggling with SuiteScript 2.0. I am a beginner on SuiteScript and this is my first script.

I check all parameters on the record and the script is well deployed and activate on the record.

I test on a function pageInit to eventually pop up a window  on page init but even this doesn’t work. I don’t understand why.

Then the function fieldchange is checking if there is unicity on  a field in all records already save. It doesn’t work and I don’t know why. Execution log doesn’t appear unless the script is active and deployed.

Here is the script I try : 

/**
 * @NApiVersion 2.0
 * @NScriptType ClientScript
 * @NModuleScope Public
 */
define(['N/currentRecord', 'N/log', 'N/record', 'N/search'],
/**
 * @param{currentRecord} currentRecord
 * @param{log} log
 * @param{record} record
 * @param{search} search
 */
function(currentRecord, log, record, search) {
    

    function pageInit(scriptContext){
        var currentRecord = scriptContext.currentRecord;
        var id = currentRecord.id;

        console.log(id);
        alert({
            title: 'Hello World!',
            message: 'Click OK to continue.'+id
        });
    }

    /**
     * Function to be executed when field is changed.
     *
     * @param {Object} scriptContext
     * @param {Record} scriptContext.currentRecord - Current form record

     */
    function fieldChanged(scriptContext) {

        var currentRec = scriptContext.currentRecord;
        var po = currentRec.getValue('otherrefnum');
        var customer = currentRec.getValue('entity');

        if (scriptContext.fieldId === 'otherrefnum') {

            try {

                alert('un message important');
                console.log('un message');

                po = po.trim();

                log.error('saveRecord' , JSON.stringify(scriptContext));
                log.error('currentRecord' + JSON.stringify(currentRec));

                var exist = searchPO(customer, po);

                if (exist) {
                    alert('The po "' + currentRec.getText('otherrefnum') + '" already exists for the sales order.');
                } else {
                    return true;
                }

            }
            catch(e) {
                console.log(e);
                log.debug({
                    title: '[Error while writing PO]',
                    details: 'Error while writing PO' + (e)
                });
            }
        }
    }

    function searchPO (entity, po){
        var exist = false;

        var searchPo = search.create({
            type: search.Type.SALES_ORDER,
            filters: [["entity","is",entity],  "AND", ["otherrefnum", "is" ,po]]
        });

        var searchResultCount = searchPo.runPaged(currentRecord).count;

        if (searchResultCount > 0) {
            exist = true;
        }
        return exist;

    }

Could you help me with it ?

Thank you !
