How do I modify/extend code from a 3rd party extension?

Posted on by

I want to auto-populate a field in an sales order page that was inserted by a 3rd party extension (VersaPay).  I can't look at the code to know what page to extend or what the field is called.  I'm pretty new the AL development so if I'm thinking about this all wrong let me know!:)

    Hi, Like standard code, you can't modify it directly, you need to extend it.

    You can add dependencies property in your app.json file.

    You can find the extension info in Extension management page.

    Then redownload symbol file and you can expand it.

    But please note, Not all extensions can be extended. There are many factors related to this.

    For example:

    Extensible Property

    https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/developer/properties/devenv-extensible-property

    Richer access control for extension source in cloud environments (‘showMyCode’ -> ‘resourceExposurePolicy’)

    Hope this will help.

    Thanks.
