Residence Times: Transaction Data
(CA-AUD) 
Objects that are no longer used must still be available in the system for a specific period of time (for example, to comply with legal archiving requirements).
You can only select data for archiving when the residence time (or retention period) in the system has expired. You set up residence times in application Customizing. If these are not set, objects are not marked for archiving.

The residence time or retention period is set on the basis of calendar days and not working days (in other words, one week equals seven days, not five days).

Among other things, you can use the BAdI Archiving Object PLM_AUD: Add-On for Specific Checks to specify different residence times for different audit types.
For more information, see the Implementation Guide (IMG) for Audit Management under Control ® Audit Data Objects: Define Residence Time.
