Final answer:
When a guest applies for SNA or SSM, a case is created in GXP. If the case is pending or guaranteed, the room type is automatically updated in Opera. If the case is guaranteed, the room type is updated by the rooms controller in Opera.
Step-by-step explanation:
If a guest applies for SNA or SSM, a case will be created in GXP. If the case is pending or guaranteed, the room type will be automatically updated in Opera. This means that when a guest applies for SNA or SSM, the system creates a record in GXP, and if the case is in pending or guaranteed status, the room type information gets updated automatically in the Opera system.
On the other hand, if the case is guaranteed, the room type will be updated by the rooms controller in Opera. In this scenario, when the case is guaranteed, the rooms controller manually updates the room type in the Opera system.
