SAP Term: resumable exception

• Key Concepts: 
  Resumable exceptions are a feature of the ABAP runtime environment that allow a program to be interrupted and then resumed at a later time. This is useful for long-running programs that may need to be paused due to system or user errors. The program can then be resumed from the point of interruption, allowing the user to continue without having to start over from the beginning. 
  
  How to use it: 
  In order to use resumable exceptions, the program must first be set up with the appropriate exception classes. These classes define which errors can be handled by the program and how they should be handled. Once this is done, the program can be run as normal. If an error occurs that is defined in one of the exception classes, the program will be interrupted and can then be resumed at a later time. 
  
  Tips & Tricks: 
  When setting up resumable exceptions, it is important to make sure that all possible errors are accounted for. This will ensure that the program can handle any unexpected errors that may occur during execution. Additionally, it is important to make sure that all necessary data is saved before resuming the program, as any changes made since the interruption will not be saved.
