Aloha POS: Error 79 - (0xC0068079) - Error applying comp


Technical Teams, Engineers, Product Managers

Description of Issue:

A coupon applied at checkout will reduce the check, but when it's committed to the store it will fail with the 0xC079 error.  

Error Details: System.Exception: Error applying comp xxx amount x.xx for check with ID: xxxxxxx ---> 
System.Runtime.InteropServices.COMException: Exception from HRESULT: 0xC0068079



Confirm the comp has the setting "Enter amount" flagged.  If this is not flagged, Olo will not have the ability to communicate the discount amount to Aloha.  


  1. Open CFC and navigate to Maintenance>Payments>Comps
  2. Locate the comp ID that failed.
  3. Check the box that reads "Enter amount". 
  4. Refresh POS.
