This program, in cooperation with a C program, is used to transmit corporate vehicle movements to Hertz's CARRENT Vehicle Tracking system, and is usually run periodically by cron (in "near-real-time"). Vehicle movements are created by opening, closing and voiding RAs and by opening and closing non-Rev tickets. In addition, the Whitefeed program used in the Americas also sends no-showed reservations that have a OKC Confirmation number (outside the Americas, no-shows are sent as part of the GAR feed). As of this writing, CARS+ supports the following three whitefeed record layouts:
| Hertz Record Layout |

A separate CARS+ program, CARRENT MQVEH sends the vehicles themselves movements to the same CARRENT Vehicle Tracking system in OKC. That program is documented in a separate chapter.
The C program, (see the chart above), uses the common MQ program configuration items. See MQ C program configuration items.

PROGRAM INVOLVED WITHIN THE AMERICAS
Only the single CARS+ program listed in the chart above is involved in CARRENT Whitefeed for the Americas.
PROGRAMS INVOLVED OUTSIDE THE AMERICAS
The following are the programs that are involved in CARRENT Whitefeed for countries outside the Americas:
| Asia/Pacific |
Europe |
Description |
Set up |
| HCWFQU |
ECWFQU |
This is the program that queues up transactions for transmission. |
|
| HCWFSN |
ECWFSN |
This is the program that actually sends queued up transactions to OKC via MQ Series. |
Set this program to be run as a CRON job in near-real-time |
| HCWFRQ |
ECWFRQ |
This program is used to manually re-queue a transaction for transmission. |
|
| HCWFED |
ECWFED |
This program produces a summary file of all data sent in the
past 24 hours. This file is also sent to OKC (it is picked up via ftp by EAI) and will be used to compare against the records
OKC says that they received. |
This program must be set up in the CRON to be run once a day
after whatever time is appropriate for the response file sent from OKC. Forms must be filled out to apply to Hertz EAI department for the file pickup. |
RA Open
RA Close
Void RA
RA Mult
Longterm Rentals
Non-Rev Movement Entry (in all of it's various forms)
No-Show Processing (for reservations in the Americas)
An array that repeats 50 times appears in the record layouts used in the Americas. This array allows for up to fifty no-showed reservations to be sent in a single record. If more than 50 reservations have been no-showed, additional records will be used.
RA movements are queued up for transmission via a record being written in the XREFIL file. This record will have the value "A" in the Xre-to field and "H" in the field Xre-from. This means that the condition of the RA will be that of when the send program is run, not necessarily the status when it was originally queued. For example, if an RA is both opened and voided between the time of the last near-real-time transmission and the next transmission, only the status Void will be reported to OKC.
Non-Revs are are queued up for transmission via a record being written in the XREFIL file as part of the F1 save logic within Non-Rev Movement Entry.
No-Showed reservations are selected by status and Mod-date on the first transmission of the day.
RA movements are written directly to the whitefeed batch file as part of the F1 save logic within RA Open, RA Close and Void RA. Operations outside the Americas do not have the status change problem mentioned under the Americas above. An RA that is both opened and voided between the time of the last near-real-time transmission and the next transmission, will have both an open and a void sent to OKC.
Non-Revs are written directly to the whitefeed batch file as part of the F1 save logic within Non-Rev Movement Entry.
No-Showed reservations are selected by status and Mod-date on the first transmission of the day.
Each transaction that is queued up is transmitted one at a time. Unlike, MQVEH, this program does NOT wait for a confirmation from OKC, all records are treated as if they were transmitted successfully.
- RAs are re-written with the transmission date/time in a field that appears on the G subwindow of RA Open (note the RA's Mod Date and Time is NOT updated).
- The XREFIL record is deleted (for the Americas).
- For non-Revs the transmission date is written to Nrv-cwf-date. This field gets re-written when a closed non-rev ticket is sent.
