Developing the extension

We've structured our project folder as follows:

We have an Src folder and under that we have a subfolder for every functionality and then for object type.

The name of each AL file is created using Microsoft's naming guidelines:

• Each file name must start with the corresponding type and ID, followed by a dot for full objects or a dash for extensions:
  • Full objects: <Type><Id>.<ObjectName>.al, such as Tab.50100.MyTable.al
  • Extensions: <Type><BaseId>-Ext<ObjectId>.<ObjectName>.al : page 50100 MyPage extends Customer Card such as Pag21-Ext50100.MyPage.al

• It is required to use a prefix or suffix for the name property of the fields in your extension. You would then use the Caption/CaptionML values for what to display to the user. This avoids the collision of fields between extensions:
  • A tag must be at least three characters
  • The object/field name must start or end with the tag
  • If a conflict arises, the one who registered the tag always wins...
