Unable to Save Requisition Line after hiding Amount field

Summary:

Initially in Requisition Create Page, When I select Line Type as Fixed Price Services/Credit, Amount field was mandatory in Pricing Section. Now I wanted to hide Amount field. I hid the field in Business Rules in Visual Builder Studio and its getting hidden but when I save the requisition, its throwing an error.
