Today was supposed to publish an article in English about how to Export Purchase Order Data to MS Excel templates with Dynamics AX 2012 ( Document Management ). but when i open the ax client i remembered that i forget to change the default language before left my office yesterday. as you know you can't change user default language from the user options form without being connected to the domain. so i tried to change the language directly from the database and i succeeded. find below the steps maybe you will need it some day.
