SF to AD: user is disabled one day before termination
In the standard interface of SF to AD, there is a direct mapping between activeEmploymentsCount (SF) and accountDisabled (AD). Following HR practices, the activeEmploymentsCount is inactive one day too early.
The accountStatus attribute in SF does not have this behaviour.
However, the activeEmploymentsCount is useful for future hires.
In order to have the best of both worlds, you should implement a mapping:
Switch([activeEmploymentsCount], "N/A", "1", "False", "0", Switch([accountStatus], "N/A", "ACTIVE", "False", "INACTIVE", "True"))
I suggest to take this into consideration to change the default mapping.
