NAV 2013 SQL table structure changes

aavio

Noted that in NAV 2013 all %(percentage) field representation changed to _(underscore) in SQL level

In NAV 2009
item table field - in NAV Profit %, in SQL also same as Profit %

In NAV 2013
item table field - in NAV Profit %, in SQL Profit _

may i know why all % changed to _ in NAV 2013?

aavio

i found it where

msdn.microsoft.com/en-us/library/hh167834(v=nav.71).aspx

choose Database, choose Alter, and then choose the Integration tab

Convert Identifiers
in nav 2009 have only - ."\/'
in nav 2013 - ."\/'%][

but why in NAV 2013 have to convert %?
