    The ability to preview the output of your Table Map was introduced in the “Carbon” release of the Update Set. You can read more about this feature on our wiki ( However, just want to highlight how this tool can help you when setting up custom elements of an integration.

    For a quick summary a Table Map is a way to customize the payload that you create when a record is modified within ServiceNow. This can be done on a full script basis or through individual Table Field Maps. Previously when setting up some of these integrations I would have to:
    – Modify a piece of the Table Map
    – Pull up a source record
    – Update that record
    – Find the outbound message
    – Decrypt the value

    Now with this you can just modify your table map and click the “Preview Output” button. I can do this much quicker than the previous way and very iteratively go through piece by piece and make my changes.

    I can also go back and test a record in production using this to see what the output is, WITHOUT having to update the record.
