Set up the number of lines per page in 'Setup Layouts' to 16.
Load the WTP and select Remittances 'Printed Cheque'. When saving the payments, if a Trader has more than 16 lines you will get a message alerting you to the potential cheque layout problem
Say 'Yes' to de-select, you will then get the following message:
Say 'No' and click Chq Nos and the Reset button to re-allocate the cheque numbers.
Once numbers are reset you can now click 'Save' and print the remittance cheques as normal.
To print your de-selected trader, run a new WTP just for the one trader, loading a blank sheet of paper before the cheque sheet. Once loaded and clicking save you will get the same messages as before but this time say 'No' to de-selecting and 'Yes' to continue with save.
