There is a potential problem if No verification is specified for a field and the field receives a validation error for some reason during processing (the format specification is too rigid, for example). You will not know it, because it will not show up in Verify. As a consequence, the data for the field will be missing from the transferred output.
If this happens with even one field in a line item table, the table will not be displayed in Verify and none of the line item data will be included in the output.
Remove the No verification setting in the field profile so that the field shows up in Verify in case it cannot be automatically validated correctly.
Remove the field from the invoice profile if it is not needed.
Specify a more forgiving format specification for the line item field that does not show up in Verify so that it can be validated. A format specification such as {N(1-2)X[-/]N(4)|N(4)X[-/]N(1-2)} could be validated more easily as X(1-50), for example.
