3. Drilling down to the parent type of an object in the AOT.

As part of my series on “Things new X++ Developers Should know”. I have been writing a few basic howtos for new X++ Developers.

Today’s post relates to quickly navigating to the source or parent type of an object in the AOT. This is often useful to drill through to a parent object to discover, debug or modify properties and code. The following are some examples of drill-downs you can perform

1. Open the Data Dictionary Table from a Form’s datasource
2. Open the Data Dictionary Enum used from a table field
3. Open the Extended Data Type used by a table field
4. Open the AOT Form object (or class, report etc) from a Menu-item object
5. Open the Data Dictionary Table object from a Query datasource
6. Open a parent EDT from an extended EDT
7. Open a parent class from an extending class.

Steps

2. Right click on the field.
3. Select “Add-ins”
