Unique business partner tax number

When a tax number is specified for a business partner, a warning message is displayed if the same tax number exists for a different business partner. This functionality has now been extended.

Users can specify if a warning message must be displayed or if specification of a non-unique tax number must be blocked for a business partner. This is controlled by the Unique Tax Number parameter in the Tax Parameters (tctax0100m000) session, which can be set to Warning or Blocking. Warning is the default value.
