ax2012-how to create configuration key and database log in custom table

if we had custom table in ax 2012, we cannot find the custom table in database log wizard

so this is the solution

1. open AOT
2. create the Configuration Key (see the picture below)
3. in this sample, I make a new configuration key called RON_CustomConfigurationKey, so every custom table that I made will be added in this configuration key
4. save it and compile
5. next step is, select the custom table that you want to log (see the picture below) 
6. Look up the ConfigurationKey in table Properties, and choose RON_CustomConfigurationKey
7. save it and compile
8. Open AX, -> System Administration->Setup->Database->Database Log Setup 
9. press new button, and next
10. choose “show all tables” if we cannot find in “show main tables”
11. find RON Configuration Key, check it, and done

you can see the log if there were transaction in this table
