If the “Sales order details performance enhancement” and “Sales quotations details performance enhancement” features are activated, the default view/edit mode setting is ignored, and the list of new Sales orders/Quotations and new Order is always opened in the editable view.
It means that the list of the Orders is opened in the editable view and the lines can be at once edit. Also, if a new Order or Quotation is created, the system will at once automatically add to it new empty line ready for editing. If after the creation a new Sales order, go back to the list of Orders using arrow on top of the form, the list will be in editable view.
Activating the “Sales order details performance enhancement” and “Sales quotations details performance enhancement” features can improve system performance when working with Orders, but the default editable view of Orders and Quotations — without the option to disable it — negates their potential benefits.
I hope this bug will be resolved.
