SaleEvent_DuplicateSale

When Posting invoices to the Sales endpoints You may encounter the error: 

{
"Errors": [
{
"Name": "ValidationWarning",
"Message": "SaleEvent_DuplicateSale",
"AdditionalDetails": "EventId:(SaleEvent)",
"ErrorCode": 4332,
"Severity": "Warning",
"LearnMore": null
},

This error is caused by a duplicate Invoice number on the POST request, You will need to edit the "number" field within the body request so this is a unique invoice number. You can also remove the number field and this will auto-populate the next invoice number in the queue.

"Number": "ABC123",

If you wish to POST duplicate invoice numbers there is a setting in the UI the Administrator of the company file can disable.
