A new purchase requisition order can be manually created by clicking on the New button. A purchase requisition number is automatically assigned. The remaining data have then to be entered, namely the order date, the quantity to order and the requirement date. At this stage, the other fields are optional.
When a purchase requisition order has been manually created, a resource (or a positive quantity) has been created in the projected profile of the inventory, which will be taken into account by the future MRP calculations.
