The data upload of an "Invoice Document Posting" produces errors when there are changes required in the header area of the document.
This issue is caused during the "Recording" process. To rectify the issue please follow the instructions given below:
When recording the transaction and it is time to press the "header" button, type in "=RBKP" (without the quotes) in the command box and press the green tick button. Now you are in the header screen. Complete your changes in this screen and then type "=back" (without the quotes) in the command box and press the green tick button. You will now be back in the first screen. Press the save button to post the document.
After entering data in your spreadsheet and then uploading it, you will see that the invoice will be posted and the invoice document number will be listed in the log file.
