The term, ARP or Account Reconcilement Plan, is an industry standard format that is also known as Positive Pay.
To find Positive Pay, launch the BankRec application.
In the BankRec application, click on “ARP Export” under the “Misc” header on the left side of the window. ARP is the same as Positive Pay.
In the ARP Export Window, click on the drop-down menu next to “Bank” and select a bank from the list.
Select a date range to search and click on the “Refresh” button.
The list of transactions can be narrowed down further by inputting a range of check numbers and clicking on the “Refresh” button again.
When all the transactions to be exported appear in the Transactions list, click on the “Export” button to export the data to a file. A browser window will appear. Use this to navigate to the desired folder and click “Save”. The data will be saved to a text file in that folder. This can be done multiple times for the same transaction if needed. 
After the file is saved, it can then be uploaded to the bank. This is the Positive Pay/ARP file.
