better error handling for inactive resources

Registered by Ferdinand

example: account code must be unique per company
if an account is inactive there is an error message something like "duplicate code" ....
if the code of an inactive account is used again.
BUT no one can see this account ....
would be helpful to get a better error message and the possibility to display inactive records
