## Description
|

Variables declarations should be ordered by type. In general, object and complex variable types are listed first followed by simple variables. The order should be:
|
|
|
|
- Record
|
|
- Report
|
|
- Codeunit
|
|
- XmlPort
|
|
- Page
|
|
- Query
|
|
- Notification
|
|
- BigText
|
|
- DateFormula
|
|
- RecordId
|
|
- RecordRef
|
|
- FieldRef
|
|
- FilterPageBuilder
|
