Do not write functions that have high class coupling. This makes the code hard to maintain.
|
|
|
|
Bad code
|
|
|
|
Any procedure / trigger that has class coupling of > 30

Good code

|
|
Any procedure / trigger that has class coupling of <= 30\.
|

Class coupling is computed by summing the unique instances of the following in a code block:
|
|
- every unique usage of a complex C/AL data type (table, codeunit, etc) as 1\.
|
|
- every unique usage of a DotNet type as 1\.
