• Key Concepts: 
  A one-way link in SAP Plant Maintenance (PM) is a connection between two objects that allows data to be transferred from one object to another. This type of link is unidirectional, meaning that data can only be transferred from the source object to the target object. It cannot be transferred back from the target object to the source object. 
  
  How to use it: 
  One-way links are used in SAP PM to connect two objects, such as a functional location and an equipment, so that data can be transferred from one object to another. To create a one-way link, you must first select the source object and then select the target object. Once the link is created, data can be transferred from the source object to the target object. 
  
  Tips & Tricks: 
  When creating a one-way link, it is important to remember that data can only be transferred from the source object to the target object. It cannot be transferred back from the target object to the source object. Additionally, it is important to ensure that all necessary data is transferred when creating a one-way link.
