Using AfterSubmit UserEventScript with SuiteScript 2.0 - suitescript2.0

Question

I'm pretty new to SuiteScript 2.0, so far it has been an insane learning experience.
Currently I am trying to write a script that will take a new Item Fulfillment record that is just being created, get the newly generated ID and place that value onto another record. I have been trying to test this by setting the value of a field on the same record with no luck. The script will run, but nothing sticks. The field I am setting the value of always remains blank.
/**
#NapiVersion 2.0
#NScriptType UserEventScript
*/
define(['N/record'],
function(record) {
function afterSubmit(scriptContext) {
if (scriptContext.type !== scriptContext.UserEventType.CREATE)
return;
var rec = scriptContext.newRecord;
rec.load({
type: record.type.ITEMFULFILLMENT,
id: rec
});
var itemFul = rec.getValue({
fieldId : 'tranid'
});
rec.setValue({
fieldId: 'custbody_mod_billoflading_ref',
value: itemFul
});
rec.save();
};
return{
afterSubmit: afterSubmit
};
});
What am I doing wrong? Again I am fairly new to SuiteScript 2.0 and learning a ton along the way! I appreciate any help I can get!

Answer 1

First of all, is your UserEvent deployment on an Item Fulfillment?
If YES, there's no need of loading the record again
However, you will need to load the 'other' record in which you need to set the value. Store the loaded record in a variable
var otherRecord = rec.load({
type: 'OTHER RECORD TYPE'
id: 'OTHER RECORD ID'
});
Also, you are trying to perform setValue on the current Record (i.e. rec)
You will need to do setValue on the record you loaded, following a record.save() to save it.
otherRecord.setValue({
fieldId: 'custbody_mod_billoflading_ref'
value: itemFul //your code variable
});
otherRecord.save();
ALTERNATIVELY,
You can use record.submitFields() API which would make your life much easier. Syntax is as below -
var id = record.submitFields({
type: record.Type.SALES_ORDER,
id: 1,
values: {
memo: 'ABC'
},
options: {
enableSourcing: false,
ignoreMandatoryFields : true
}
});
