• Key Concepts: 
  Reference time is a concept used in SAP Plant Maintenance (PM) to define the time period for which a maintenance task is planned. It is used to determine when a task should be completed and when it should be started. Reference time can be set for individual tasks or for entire maintenance plans. 
  
  How to use it: 
  Reference time can be set in the SAP PM system by entering the start and end dates for the task or plan. The system will then calculate the duration of the task or plan based on these dates. The reference time can also be adjusted if needed, such as if the task needs to be completed sooner or later than originally planned. 
  
  Tips & Tricks: 
  When setting reference time, it is important to consider any external factors that may affect the completion of the task or plan. For example, if there are holidays or other events that may delay the completion of the task, it is important to factor this into the reference time. 
  
  Related Information: 
  Reference time is closely related to scheduling in SAP PM. Scheduling is used to determine when tasks should be started and completed based on their reference time and any external factors that may affect them. Scheduling can also be used to adjust tasks if needed, such as if a task needs to be completed sooner or later than originally planned.
