Set up positive pay to generate an electronic list of checks that is provided to the bank. Then, when a check is presented to the bank, the bank compares it with the list of checks. If the check matches a check in the list, the bank clears it. If the check doesn’t match a check in the list, the bank holds it for review.

Most of the set up for Positive Pay follows standard Business Central processes. See Export a Positive Pay File – Business Central | Microsoft Docs for more in-depth information.

  1. In the bank account card, in the Transfer section, select a Positive Pay Export Format.

  1. Go to the Data Exchange Definitions page.
  1. Select the Positive Pay Export Format associated with the bank account you are configuring. In this example, we are using CITIBANK-PP.
  1. In the Ext. Data Handling Codeunit field, add the Mekorma codeunit: 70819738 (MEK PH AB Posi Pay Handler). Bank accounts must have a Positive Pay Export format and the proper Ext. Data Handling Codeunit assigned, otherwise that bank account line will display an error in Action Board.
