Hi JZama110492 , are you using fully inventoried items? AccountRight will not allow an item sale to be recorded if there is insufficient stock for an item. In the program itself, you will get a prompt for each such item, to make some correction to allow the sale to go through. However, when importing, those options are not available.
If you examine the log, and find an invoice with that error, check each item on that invoice and see if any of them do not have enough stock. You could consider entering a stock adjustment to increase the onhand quantity.
We have created a custom program for a client which imports item sales from various CSV or Excel files , and the program checks the stock on hand for every item. If there is not enough, the invoice is changed to an order so that the import will go through. However, the standard import program does not have that kind of flexibility.
Regarding the job numbers, you will need to check the job numbers in the file and make sure they exist in the data file before importing; the import process does not create missing job numbers.
