Problem:
1. SICS abends when tick new parameter "auto booking on OCC&ORP" if OCC protects multiple IAB already
2. Close TW successfully even though protecting OCC isn't register complete
3. The OCC can protects multiple IABs even though having tick "Auto booking on OCC &ORP"

Solution:
1. When a prop treaty OCC already protects multiple IAB and the user select the parameter "Auto Booking on OCC ORP" make sure a new error message appears with e.g. the following text "This business protects more than IAB, not allowed to do automatic bookings on OCC & ORP"
2. When booking takes place on an IAB, on multiple sections and each section is protected by different OCCs and at least one of the OCC does not have the Registration Complete flag set (and this is required by the system parameter Require Complete Registration), make sure it is not possible to set the status to Closed on the IAB worksheet. To inform the user about this a new error message appears with e.g. the following text "Worksheet cannot be closed since at least one of the protection OCCs does not have the Registration Complete set".
In case the system parameter Require Complete Registration is NOT activated, then the worksheet can be closed and this message should not be presented.
3. When a prop treaty OCC protects two different sections on one IAB and the OCC is marked with "Auto Booking on OCC ORP", make sure it is not possible to protect a section on another IAB with the same OCC. An error message should appear with e.g. the following text "This OCC cannot protect this business since it already protects another IAB".
