Fill duedate field based on value of terms field - netsuite

Question

Is it possible to fill the duedate field based on the terms field? For example, I have a date in the duedate field, but I want to extend it based on the terms field. How can I do it? Through Suitescript or workflow?
The code is incomplete because I don’t know if I’m on the right path.
(NB: It is a user event)
function beforeLoad(context) {
}
function beforeSubmit(context) {
}
function afterSubmit(context) {
var dataEntrega = context.currentRecord
currentRecordRecord.getValue({
fieldId: 'duedate'
})
var dataCondicoes = context.currentRecord
currentRecord.getValue({
fieldId: 'terms'
})
}
return {
beforeLoad: beforeLoad,
beforeSubmit: beforeSubmit,
afterSubmit: afterSubmit
}

Answer 1

Why do you need to script this? I believe the due date is calculated based on the terms out of the box, no need for scripting

Answer 2

The following code should work. Depending on your needs I recommend adding some limitations to when this logic is executed. For example you can only execute based on if the transaction/record mode is create/copy (decide if you want to include edit or not). You can also check the status of the transaction, and only execute if the status is not partially paid/paid in full...
function afterSubmit(context) {
//load record
var curRec = context.newRecord; //can substitute "context.oldRecord", or "currentRecord.get();"
//get current due date
var transDueDate = curRec.getValue({fieldId: 'duedate'});
//get the terms, this will likely come as an internal id. use getText if you want the text.
var transTerms = curRec.getValue({fieldId: 'terms'});
//empty string to hold terms as a number of days
var addtlDays;
//transform the internal id to terms as a number of days
switch (transTerms){
case 1: // Ex: 1 = internal id for term "Net 15"
addtlDays = 15;
break;
case 2: // Ex: 2 = internal id for term "Net 30"
addtlDays = 30;
break;
//add additional case statements as needed
default:
addtlDays = 0;
}
//calculuate the new due date
var d = new Date(transDueDate);
var newDueDate = d.setDate(d.getDate() + addtlDays);
//set the new due date
curRec.setValue({
fieldId: 'duedate',
value: newDueDate,
ignoreFieldChange: true //optional, default is false
});
}
