  Key Concepts: 
  Change Documents are used to document changes made to the master data of a Plant Maintenance (PM) system. They are used to track changes made to the system, such as changes to equipment, functional locations, and other objects. Collective Purchase Requisitions are used to create multiple purchase requisitions at once. This is useful for creating multiple requisitions for the same item or for creating multiple requisitions for different items.
