Hi all does any one know how to hide line item field through scripting ?

hiding an essential mandatory field is evil

Yes battk I am sure I want to hide it

use the form from a user event beforeLoad to get the sublist and then the field and then update the display type to hidden

Sample to hide the rate for instance

scriptContext.form.getSublist('item').getField('rate').updateDisplayType({displayType: serverWidget.FieldDisplayType.HIDDEN});
