View Adjustment and Override Codes


Adjustment and Override Codes

There are a great many ways to adjust or override various default and specified settings and configuration items within the Hudson suite of applications.  This flexibility and configurability is what distances Hudson from its competitors.   The codes listed below are used in various areas (mainly in FareOptions fields of fare files, as well as within specific Group / Sales profiles) to change, adjust or override system settings.

Samples of things that may be adjusted or overridden are:

  • Tolls
  • Parking
  • Web Discount Amounts
  • Return Discount Amounts
  • Reservation Lead Time, and many more items.


The formatting of the strings used to adjust and override is:

Note that there are 3 components to the above string:
  1. Key - the item to be modified
    1. Fare Option Keys
    2. Profile Option Keys
  2. Adjustment - how / for whom the adjustment is to be applied
  3. Value - the amount or value of the adjustment


Fare Options

Here is a list of the  "keys", codes that may be used with Fare (location) options.  The formatted string outlined above, would be inserted in the FareOptions Column(s), per location, and per service (an adjustment might apply to one, two, several or all service types, depending on your specific need). The keys are the 3 letter codes below, bordered by "   "   and are assumed to be unique. Similar functions should be defined with different values.

Profile Options

These keys will be applied within specific profiles (typically on the Rules Tab, in Base Fare Exceptions, Gratuity Exceptions, Discount Exceptions fields, etc.).

"DSC"        ’ Discount rules (fare component rules index)

"RLT"        ’ Reservation lead time override type
"RLV"        ’ Reservation lead time override values
"RLA"        ’ Reservation lead time override after time
"RLB"        ’ Reservation lead time override before time


This is a list of the codes that are used, before the " : " that indicate how the adjustment is to be applied:  Should it be applied per reservation, per passenger, overridden, change the percentage, etc.   In some cases, and for some Keys, no Adjustment code is required. For example, using CCR from the list above, all by itself, indicates that a Credit Card is required for this location - no Adjustment or Value is required.

  • N          No adjustment
  • F           Fixed adjustment
  • F2         Fixed adjustment per passenger
  • FE        Fixed adjustment per extra stop
  • O          Override value
  • O2        Override value per passenger
  • OE        Override value per extra stop
  • P           Percentage (override)
  • R          Percentage rounded to nearest ($) (override)
  • U          Percentage rounded up to nearest ($) (override)


This is essentially the numeric amount that should be used in adjusting or overriding the system default.  This numeric value may correspond to a dollar amount, a percentage,  a fare key an Affiliate ID or Sales Profile ID. .  The number is usually expressed as a whole number but may also be written in decimal format ( $2.50 = 2.5 ).  Some of the keys above, do not require any Adjustment or Value setting.  For example, inserting CCR in the fare options field for Service1 at a specific location will require a Credit Card to be captured during ALL Service 1 reservations for that location.


  • RDA=F:3      Return Discount Adjustment=Fixed $3
  • RDA=O2:10     Return Discount Adjustment= Override Per Passenger $10
  • RDA=P:5     Return Discount Adjustment = Percent Override 5%
Several overrides may appear within a single Fare Options or Profile Exceptions field and should be separated by a single comma, and no spaces.  For example:


The three keys below are a little different and are applied in a similar fashion to the ones listed above but are used infrequently. 

"AAI"            ’ Location auto link affiliate ID
"SA1"            ’ Sales ID 1
"SA2"            ’ Sales ID 2

AAI is specific to  making a reservation for a location that is an affiliate location - we have the option to specify in the location, to automatically link it to an affilliate profile when saving the reservation. ex: AAI=123, where 123 is the Affilliates ID.

SA1 and SA2 work in the same fashion: when you select a location on the Fare and Availability screen that has a fare opt of SA1=555 then we will attach sales profile ID #555 to ProfileIDSales1 in the reservation.  This could be used for example if you have a Salesman who brought in a business account, and that business account address is added to the Fare File as a common pickup location. ALL trips to and from that location, regardless of who is travelling to/from there should be credited to the salesman.

For questions or assistance with the above Keys, Adjustments and Values, please contact Hudson Tech Support.

Advanced Example

Let’s assume that you wish to override a Toll setting for a location and most likely the Toll value will need to be adjusted according to the service type (larger vehicles may incur higher tolls).  Here is how that could be configured and accomplished:


  • TLO= —> Toll override
  • F:0 —> Sets default override to fixed 0
  • ^ —> Start of exceptions to set default
  • S1:10 —> specify service 1 overrides toll default from 0 to 10
  • ; —> Exception separator
  • S2:15 —> specify service 2 overrides toll default from 0 to 15
  • ; —> Exception separator
  • S3:20 —> specify service 3 overrides toll default from 0 to 20
  • and so on, and so on
