This can occur if you have a program attached to your flat rate scale that is not included on the itinerary.  When configuring flat rate scales, you choose application defaults for them, so that a certain percentage of the revenue is allocated to an item on the reservation, typically a program. You will receive this error if the flat rate scale used on the reservation has application defaults set for a certain program that is not included in the reservation itinerary.
 
First, we need to determine what program or item is causing the error message because it is the default item for the flat rate scale. 
  1. Click the hyperlink next to the yellow warning symbol to go to the flat rate scale.
  2. Make note of program(s) listed in the Flat rate application items section. If the column under Currently applied says No - not part of an itinerary, note this program or item, as it is causing the error.
If that program should be on this group reservation, we need to add the program to the itinerary:
  1. Go back to the group sale reservation summary
  2. In the itineraries box,click the name of your itinerary to access the itinerary calendar
  3. Click Add in the top right corner of the calendar
  4. Select either daily admission program or Scheduled event from the dropdown, depending on the program we need to add
  5. Add your program(s) to the itinerary
  6. Go back to the group sale reservation summary.
  7. Click Add > Add Payment under the Payments box.
If this reservation should not contain the default Flat Rate application item program but instead includes a different program, you’ll need to add that program as an application item in Flat Rate Application Items: 
  1. If the correct program is already on your itinerary, click the hyperlink next to the yellow warning symbol to go to the flat rate scale.
  2. Click on the program that is not grayed out and under the Currently Applied column says "Yes."
  3. Click Edit.
  4. Enter the amount of the reservation in the amount field, and click Save.
  5. Click next to each item that is listed that is not currently applied, and click Delete.
  6. Go back to the group sale reservation record and click Add > Add Payment under the Payments box.
  7. If the correct program is not added to your itinerary, click the hyperlink next to the yellow warning symbol to go to the flat rate scale.
  8. Click Add, search for the correct Program that should be on the itinerary, and enter in the desired amount of payment that should be applied to this program.  
  9. Click Save.
  10. Click next to each item that is listed that is not currently applied and should not be on the reservation, and click Delete.
  11. Go back to the group sale reservation record.
  12. In the itineraries box,click the name of your itinerary to access the itinerary calendar
  13. Click Add in the top right corner of the calendar
  14. Select either daily admission program or Scheduled event from the dropdown, depending on the program we need to add
  15. Add your program(s) to the itinerary
  16. Go back to the group sale reservation summary.
  17. Click Add > Add Payment under the Payments box.
If the rate scale is edited, the reservation may need to be updated to reflect this change, if the pricing is not correct:
  1.  In the reservation summary, go to the Pricing box and click Edit
  2. Change the pricing structure to Per Ticket.
  3. Save
  4. In the Pricing box, click Edit again
  5. Change the structure back to Flat Rate and select the scale
  6. Save
If you would like this program to automatically apply to the rate scale for future reservations, ensure the program is selected in the Included programs tab of the rate scale record.
