Hi SIZECO
Thanks for the detail. Looking at the information, your retail.txt file foe 7/12/2023 has 16 transactions, 6 imported without warnings and 10 with warnings.
No transactions were missed, so what I suggested earlier to JanBQ is incorrect. Normally when an import log shows an error number and no details, this usually points to blank lines at the end of the import file that were skipped.
Your detail shows this is not what is happening. What seems to be happening is for any transaction dated before today seems to be treated as a 'prior year' transaction. Note you have 10 of the 16 transactions with 4 or 6 Dec and 6 dated 7 Dec. Looks like a faulty warning message.
Regards
Gavin
