Missing sales in sales report
My Sales by Customer Detail report is missing 2 weeks of payments by customers mid last quarter. The details were imported from my bank feed but I think I forgot to put the GST code at that time. This is the only reason I can think as to why these sales aren't in the report. I can edit the details in the account history but I can't add the GST code - just "out of scope, inclusive of GST or exclusive of GST". I have chosen the correct GST allocation and still it won't appear on the aforementioned report. It means the BAS is totally wrong. What am I doing wrong and how can I fix this??
