Hi, I try to change quantity in line in item receipt by UE script in beforeLoad() function. If quantity (100) more than quantity remaining (50), value quantity = 50, i need quantity = 100. But i can open item receipt and change quantity manually.

/**

*@NApiVersion 2.x

*@NScriptType UserEventScript

*/

define(['N/search', 'N/record', 'N/task'],

function(search, record, task) {

function beforeLoad(context) {

var record = context.newRecord;

if (context.type !== context.UserEventType.CREATE) return;

var itemCount = record.getLineCount({

sublistId: 'item'

});

for (var i = 0; i < itemCount; i++ ) {

record.setSublistValue({

sublistId: 'item',

fieldId: 'quantity',

value: 100,

line: i

});

}

}

return {

beforeLoad: beforeLoad

};

});

Before load is generally not for changing values on fields/sublists, this should be handled beforeSubmit most likely, or in some sort of workflow action while the record is submitted.

I use before load because i need to show quantity to user

@Rodion beforeLoad is not designed or recommended to change values. You can do what you need with a Client Script after the page load.
