Good day,

Please note that Sage 50 does not have a tool to bring back missing lines. Please check if you are able to reprint the invoice since the header exists. You can also check if the same invoice number was not used in the supplier as a document number. If the customer and the supplier have the same document numbers, Sage consolidates transactions. Run the data integrity and verify the data only and history files.

Please refer to the link below for further assistance,
