Hi Jennine

The data that is able to be purged can be seen when you create a purge type.  There isn't job assignment listed in the purge type fields so assume this isn't able to be deleted.

I thought adding an end date to the job assignment might work but the help text says Job assignment dates serve multiple purposes, from reporting to dynamic audience rules to program and certification assignments and more. However, they are not used to determine if the job assignment is active in any other part of Totara.

This means that the job assignment for the suspended user would needs to be deleted - if you overwritten with blank data the job assignment would still exist. The HR Import Job assignment source allows you to delete a specific job assignment through the idnumber field
