When importing the data into XPA, you may end up with the error message: "Tax code exists in transaction lines that does not exist in the ledger".
This means that there is a GST code in XPA that doesn't match one in the download TXT file.
Our XPA TXT file includes a tax code of "0" which comes from the client source - this needs to be also included in XPA.
To check in XPA:
Open up the client ledger.
Go to GST, then click Tax Rates.
The tax rates will appear - check to see if there is a 0 tax rate. If not, this needs to be added.
Enter the details - Code = 0; Description = Zero Rated; Account = 925/.
