Go to Common Tasks > Billing > Send Instrument Hire to Accounts to bill for loans and hire in bulk.
This script first opens the Loans & Hire File in find mode with one find request for records with 'Current' in Status and '>0' in Amount. This will find all current loans with a fee greater than zero. The request can be edited or new requests added if required.
Select Perform Find to execute the find and display the found records for review.
Select Send to Accounts and follow the prompts to enter billing period and category details. The script will then display the newly created billing line items. The displayed records can be edited or deleted if needed.
