I am a FICO consultant in our organisation we have not implimented HCM (HR module). We wanted to track employee wise expenses so we have created statistical internal order as employee code.
And through substitution I post the data to personnel number field (IO get substituted to pers no)
Now as we do not have Hr module implimented, system gives me error that personnel number is invalid. So I wanted to deactivate this personnel number check (validation). How can we do so?
