To Enable Database Log for Table in Ax 2012 you can follow below steps.
Go to system Administration ->setup ->Database->Database Log Setup
![Database log]( "Database log")
After clicking Database Log setup you need to select your table if you are not getting your table then click on show all tables then you can get your table too.
Then Complete wizard as per requirement of enabling log for insert,update,delete on fields or table.
I want to suggest do not take all tables its will effect performance of ERP.
If log are not getting generated after setting all steps then you need to check table property and savedatapercompany should yes to work that.
But you can user savedatapercompany property only if your table is empty.
