A Reservation for goods Issue can be requested by various departments by various account assignment objects (such as cost center, order, assets)
It is used to plan an inward movement in advance.
A Reservation ensures that material is available when it is needed
It is also simplified and accelerates the goods issue process and prepares the task at the point of goods issue.
Reservation can be taken into account by MRP so that a required material can be procured quickly if it is not available in the warehouse.
A Reservation results in an entry in the requirement-planning file.
