A material requisition is a request made by the warehouse keeper or warehouse manager to deliver a requested material through a work order for the execution of a task.
Material requisitions are generated automatically when adding an inventory-type resource to a work order. So, once the material request is made in a work order, a material requisition is generated that must be validated by the warehouse keeper from the "Material Requisitions" tab.
Finally, after validation, the warehouse keeper must process the material release in the "Releases" tab so that the value is deducted from the warehouse stock (referring to the release type by WO, so the system shows all items requested through that material requisition).
