In order to automate the process, you should first set up the Currency Exchange Rate Services function on Microsoft Dynamics NAV. This is a tool that helps you to connect with external service providers like Yahoo, Bank of Canada, European Central Bank, etc.
Navigate to the Currency Exchange Rate Services window by using the search option. If you haven’t added an exchange rate service provider, click on “New”. The action will open a new window where you have to enter the code, description, etc. Choose the code and description and enter the url of the service provider in the Service url section.
In order to map the required currency exchange rate fields, scroll down to the “Field Mapping” section on the same window. Under the “Parent Node for Currency Code” row, click on “Source” section. You should see ellipsis that will take you to the “Edit – Select Source” window. You can select the currency for the parent node here and click “ok”. You have to do the same for all the fields in this section.
In the last row – Relational Exch. Rate Amount – you can enter the default value. For example, if you are using Euro, you must enter 1 in the “Default Value” field, which means the system is comparing the foreign currencies to 1 Euro. In order to check if the system has been setup correctly, click on the “Preview” and check the values.
