Select a single line sample on the line containing the voucher number and define the fields (BR, DEBIT, CREDIT, TLR) as normal and OK the template.
Select the same “voucher” line again and create a new append template. Highlight a field that covers the same column positions as the “reversal of…” text. Double click the field and select the “after last field in template” option from the Start field section of the advanced tab.
Bring in the date as a separate footer template
