I’m trying to create a Vendor Bill in dynamic mode inside the POST method of a Restlet script.

The issue I’m experiencing is that I cannot set some fields, specifically:

• subsidiary

• location

• department

• class

Here is the error I’m getting:

{

"type": "error.SuiteScriptError",

"name": "INVALID_FLD_VALUE",

"message": "You have entered an Invalid Field Value 5 for the following field: subsidiary"

}

Code snippet:

const transactionRec = record.create({
    type: record.Type.VENDOR_BILL,
    isDynamic: true,
});

transactionRec.setValue({
    fieldId: 'entity',
    value: requestBody.body.vendor,
    ignoreFieldChange: true,
});

transactionRec.setValue({
    fieldId: 'subsidiary',
    value: requestBody.body.subsidiary,
});

transactionRec.setValue({
    fieldId: 'currency',
    value: requestBody.body.currency,
});

transactionRec.setValue({
    fieldId: 'tranid',
    value: requestBody.body.tranid,
});

transactionRec.setValue({
    fieldId: 'memo',
    value: requestBody.body.memo,
});

transactionRec.setValue({
    fieldId: 'department',
    value: requestBody.body.department,
});

transactionRec.setValue({
    fieldId: 'location',
    value: requestBody.body.location,
});

transactionRec.setValue({
    fieldId: 'class',
    value: requestBody.body.class,
});

What I’ve checked so far:

• The role executing the script has all the required permissions.

• The value I’m trying to set is valid (the record is active and accessible).

• Setting the fields in the UI in the same order as the script works.

• Using ignoreFieldChange: true in setValue() did not help.

Would really appreciate any insights, workarounds, or explanations — I might be missing something simple here. Thanks in advance!

P.S. Unfortunately, I cannot use standard mode for creating this transaction, because I need dynamic mode to set SuiteTax details on line items.
