Hi, Here is the sample code that you can try, this is for customer but you need to make changes as per your requirement CustomFieldRef[] customFieldRefArray = new CustomFieldRef[1]; BooleanCustomFieldRef booleancCustomeFields = new BooleanCustomFieldRef(); //change this as per the field type.…

Is this still open? Hope you found the solution

Hi still this requirement is open? For this, we need to use an external suitelet without login but this is not suggestable. With external suitelet we have less security.

Got the solution for the same, we have some feature that we need to enable and which is available under Setup >> Accounting >> Accounting Preference >> General (tab) - General Ledger(section).
