When importing a file through Cash Receipts import, if an error occurs the other line items within the file go ahead and import into the batch. Then you have to fix the items in your file and add one by one OR delete the batch and start over to re-upload your file. Another similar software I worked with would allow you to choose an option to "Decline File if Failures Occur" meaning, if there are ANY fatal failures then the entire file would need to be fixed and re-uploaded.
