What’s happening?
This is with duplicate receipt numbers being generated in the POS system for their store.


Reason:
The duplication of receipt numbers may occur due to having the CPOS application open in multiple tabs, which is not supported and can lead to issues including duplicate receipt IDs.


Resolution:

  • Validate that the numbering format used to generate Receipt IDs will create unique IDs (for example, {Store}-{Terminal}-{DateOfYear + NumberSequence}), ensuring they are unique across different transaction types.
  • If using the Sequence property for some or all receipt types, include dynamic date characters (for example, "ddd", "MM", "DD", and "YY") to help prevent duplicate receipt IDs. Additionally, it is recommended to have a character that is unique to that transaction type.
  • Enable the "Retrieve the latest number sequence data" setting to mitigate this.
