• Key Concepts: 
  Start-start relationship is a type of relationship in the SAP Project System (PS) module. It is used to define the relationship between two activities, where the start of one activity is dependent on the start of another activity. This type of relationship is also known as a “hard” relationship, as it requires that both activities must start at the same time. 
  
  How to use it: 
  Start-start relationships can be created in the PS module by selecting two activities and then selecting “Start-Start” from the drop-down menu. This will create a link between the two activities, indicating that they must start at the same time. The duration of each activity can then be adjusted to ensure that they both finish at the same time. 
  
  Tips & Tricks: 
  When creating start-start relationships, it is important to consider how long each activity will take to complete. If one activity takes longer than the other, then it may be necessary to adjust the duration of one or both activities in order to ensure that they both finish at the same time. 
  
  Related Information: 
  Start-start relationships are just one type of relationship that can be created in the PS module. Other types of relationships include finish-finish, start-finish, and finish-start. Each type of relationship has its own unique characteristics and should be used appropriately depending on the needs of the project.
