Inventory Parameters and Settings

In case your interface does not transmit full reservations and blocks both ways, inventory may be out of sync in either system and adjusted with the help of an inventory snapshot.

This is usually sent from a OPERA PMS to OPERA ORS to update ORS with inventory changes at the property that have not been transmitted through the interface. This inventory snapshot contains the total sold count, overbooking level, and out of order rooms per day per room type. It further splits the sold counts into transient and block bookings, as well as definite and tentative bookings.

For example, CLS PMS receives reservations from ORS only and does not send its own reservations back. This means ORS does not know what the exact availability in the PMS is. To make sure ORS has exact sold counts and does not mistakenly overbook the hotel, CLS PMS sends an inventory snapshot to ORS, containing full reservation and block counts. When OXI-HUB receives this inventory snapshot it directly updates the availability tables for transient reservations and blocks for this property, and thus has an accurate picture of the number of rooms that are still available.

All parameters are set at the global level.

Table 23-5 Inventory Parameters and Settings

Parameter Name	Parameter Value	Direction of transmission where parameter applies.Parameter Description	Recommended Setting
CHANGE TO INVENTORY GENERATES	INVENTORY RTAV	-> Direction: OPERA to External System only. When a Change in Inventory (Overbooking or External Allowance) occurs in OPERA and Inventory business event "AVAILABILITY/% ALLOWANCE" or "CONFIGURATION/% INVENTORY CONTROL" is generated, OXI can use these event in different ways. - Set to INVENTORY, As is continue to generate the Inventory messages for the above Business Events. - Set to RTAV, Generate the RTAV XML messages instead of Inventory messages for the above Business Events.	Set accordingly.
ENABLE ALLOWANCE	Y/N	-Direction: Data from OPERA To External System. Inventory allowance for external systems.	Set accordingly.
EXTERNAL PHYSICAL ROOMS	Y/N	-> Direction: Data from external system to OPERA. Applies mainly to OPERA S&C in this case. The hotel might not allow OPERA S&C to sell its full physical room capacity. Although the hotel has 100 rooms it may allow only 50 rooms to be sold by the S&C. In this case the physical rooms should be calculated from the inventory snapshot the external system sends to S&C to make sure only 50 rooms are considered. In this case the parameter would be set to Y. Set it to N if OPERA S&C has the entire physical room inventory from which the sold counts shall be calculated.	If your OPERA is an S&C standalone install, physical room inventory might not be configured and should be updated by the external system.
INV ROOMCLASS	N - No OO - Overbook Only YP - Physical Rooms for Suite YS - Suite as a Single Unit	-> Direction: Data from OPERA to external system The external system may accept the Room Class totals in the RTAV message. Set the parameter to 'YP' to include Room Class totals in the RTAV message. For Suites (Virtual Rooms), actual physical rooms comprising the Suite will be used for the Room Class totals. Set the parameter to 'YS' to include Room Class totals in the RTAV message. Each Suite (Virtual Room) will be treated as a single unit for the Room Class totals. Set the parameter to 'OO' to only send overbook counts in the RTAV message. Set it to 'N', if Room Class totals are not to be included in RTAV messages.	When the General > Room Class and General > Component Rooms application functions are set to Y and the Inventory > INV_ROOMCLASS OXI Parameter is set to YS, Physical Room Types and Component Room Types cannot be attached to the same Room Class. Also, only 1 Component Room Type can be attached to a Room Class.
INV SNAPSHOT BLOCKS	Y/N	-> Direction: Data from external system to OPERA. Applies mainly to OPERA S&C in this case. If blocks are not transmitted both ways in this interface but the external system creates blocks that affect its inventory, this parameter should be set to Y. In this case block inventory will be updated in the OPERA S&C inventory tables from the inventory snapshot sent by external system. Set this parameter to N if it is not necessary to update the OPERA S&C block inventory from the snapshot. This would be the case if blocks are transmitted fully both ways, or if the external system does not create any blocks at all.	If your OPERA is an S&C standalone install, set accordingly.
INV SNAPSHOT RES	Y/N	-> Direction: Data from external system to OPERA. Applies mainly to OPERA S&C in this case. If reservations are not transmitted both ways in this interface but the external system creates reservations that affect its inventory, this parameter should be set to Y. In this case transient reservation inventory will be updated in the OPERA S&C inventory tables from the inventory snapshot sent by external system. Set this parameter to N if it is not necessary to update the OPERA S&C reservation inventory from the snapshot. This would be the case if reservations are transmitted fully both ways, or if the external system does not create any reservations on its own.	If your OPERA is an S&C standalone install, set accordingly.
UPL BLOCK INFO	Y/N	-> Direction: Data from OPERA to External System. Set it to Y if OXI needs to send the block information (block code, ded type, blocked/sold count) to the external system. Set it to N if OXI does not need to send the block information to the external system.	Set as Y/N according to system needs.
