There are number of reasons for the joining date to be wrong.
- If the record was created in the old MMS, this date is actually the date the record was created.
- Some records will show “unknown” as there was not a date entered when the old MMS record was created.
- On Compass, the joining date can be entered and set to any date when the record is made.
We are looking at ways to make this information more accurate, however in the meantime, it does not have any affect on anything else.
