Reorganizing an object (e.g. order, project) normally requires three steps:

1. Setting the delete flag (can be reset)
2. Setting the final deletion indicator (cannot be reset)
3. Reorganizing (writing the object to a sequential dataset and physically deleting it from the system)


Residence time 1 determines the time interval (in calendar months) that must elapse between setting the delete flag (step 1) and setting the deletion indicator (step 2).

Residence time 2 determines the time (in calendar months) that must elapse between setting the deletion indicator (step 2) and reorganizing the object (step 3).
