Implement Extended Data Types (EDT) like they exists in "Dynamics for Finance and Operations" (formerly: AX) since a long time.

Here are the benefits of EDTs:

- Code is easier to read, because variables have a meaningful data type. For example, the data type is Name instead of Text.

- The properties that you set for an EDT are used by all instances of that type. Therefore, EDTs help reduce work and promote consistency. For example, account numbers ("Account No" data type) have the same properties throughout the system.

- You can create hierarchies of EDTs. The EDTs can inherit the appropriate properties from the parent, and you can change other properties. For example, the ItemCode data type is used as the basis for the MarkupItemCode and PriceDiscItemCode data types.
