• Key Concepts: 
  Operation-internal relationship is a term used in the SAP SCM-APO-PPS Production Planning and Detailed Scheduling component. It refers to the relationship between two operations within a production process. This relationship can be either a predecessor-successor relationship or a parallel relationship. 
  
  How to use it: 
  The operation-internal relationship is used to define the sequence of operations in a production process. The predecessor-successor relationship defines the order in which operations must be completed, while the parallel relationship defines operations that can be completed at the same time. This information is used by the system to calculate the start and end times of each operation. 
  
  Tips & Tricks: 
  When defining an operation-internal relationship, it is important to consider the resources required for each operation. If an operation requires resources that are not available at the same time, then it should be defined as a predecessor-successor relationship instead of a parallel one. 
  
  Related Information: 
  The operation-internal relationship is closely related to the resource-related relationships, which define how resources are allocated to operations. It is also related to the material flow relationships, which define how materials are moved between operations.
