Field Level permission
Just a few lines of code in the change log entry table and a table for the setup to manage permission on insert/modify/delete of fields that are under log.

Nice and simple solution

However, I will suggest changing two lines of code for performance reasons:

IF lRecUserFieldPermission.FINDSET THEN
into:
IF NOT lRecUserFieldPermission.ISEMPTY THEN

and
IF NOT lRecUserFieldPermission.FINDFIRST THEN
into:
IF lRecUserFieldPermission.ISEMPTY THEN

To improve the performance even further I would move the code to a new single instance codeunit, that loads the new table into a temporary table at first execution.
If you are using SQL and NAV2009 R2 (or later ) I will suggest considering using the new triggers in Codenit 1 to catch all kinds of modifications - both direct and indirect.

But great and simple solution - thank you for sharing
