It kind of sounds like your lines total doesn't match your deposit or credit card payment amount.

Rather then viewing the job log report which cuts off the message, open the job log and drill down to that record and keep drilling down by double clicking the entry until you can see the full message.

Is this for brand new orders or are you trying to import against existing orders?

If brand new, you need to be setting the ItemCode and the QuantityOrdered before you can try to distribute against a lot.

If existing, you need to be setting the LineKey using the Replace operation against a column in your source file. 

If doing new distributions, you need to be setting the LotSerialNo and a QuantityOrdered.

EDIT: found these two articles.

I went ask the user who entered the order, they said when a customer comes in they sell them a product and take a credit card payment and charge the card (manually calculated).  After the sale they go back to Sage and enter an order, sometimes the "deposit amount" doesn't match the "order total", they have some kind of method to bypass this and I think that is causing the error.
