## Behavioral notes
- The service builds Oracle SQL dynamically so it can expand IW requests into multiple external-user type codes.
- Production-mode execution excludes test users by consulting AppGlobal.EnvironmentService.IsProduction.

## Constraints and usage notes
- Callers must provide either a customer-group ID or a customer ID plus an external-user type code.
- The returned URL field depends on legacy clsProperties configuration for Business Online last-login navigation.
