In This post we will learn how to set sublist field value in client script. We will write a code snippet in client script which will trigger on pageinit and close all the lines of sales order item sublist.

This code is written in Suitescript 2.1

/**
 * @NApiVersion 2.1
 * @NScriptType ClientScript
 */

define(['N/record'], (record)=>{

    const pageInit = (context)=>{
         const currRecord = context.currentRecord;            
         const lines = currRecord.getLineCount({
             sublistId: 'item'
         });

         for(let i=0; i<lines; i++){

            const lineNum = currRecord .selectLine({
                sublistId: 'item',
                line: i
            });

            currRecord.setCurrentSublistValue({
                sublistId: 'item',
                fieldId: 'isclosed',
                value: true,
                ignoreFieldChange: true
            });

            currRecord.commitLine({
                sublistId: 'item'
            });
         }


    }


    return {
        pageInit: pageInit
    };

});

As you can see we are using selectline function to select the line first then using setCurrentSublistValue to finally set the field value and now we should not forget to commit the line
