1. Access the app Manage Incoming Payment Files.
2. Click on Import.
3. Select Lockbox Batch.
4. Upload the lockbox file.
5. Click on Process.

The system is not able to uniquely determine/identify customer account based on MICR number, or the invoice number (document number/reference number) provided in the lockbox file. In the context of lockbox processing, MICR numbers refer to the combination of Transit Routing Number (Bank Key) and Customer Bank Account Number.

Lockbox needs a MICR number or a journal number to identify a specific customer. It first looks at MICR number to determine the customer account. Ideally, it will be good if both (MICR & journal entry number) are provided in order for Lockbox to be able to perform clearing in Accounts Receivables. Record 5 in the lockbox file contains the customer's bank account number. It is a combination of Bank Key and Bank Account Number. This information needs to be updated in the customer master data.

Follow the below steps to maintain the bank account in the customer master data:

1. Access the app Manage Customer Master Data.
2. Go to the tab Bank Accounts.
   
3. Click on Create.
   
4. Maintain the Bank Country, Bank Key and Account Number.
5. Click on Save.
