If you every been collecting record changes or dynamically setting filters in NAV, you properly will know the concept of RecordRef and FieldRef. It is very powerful and very interesting to use.
I have used the concept to create a functionality where we can send customer records to a web service dynamically.
To make it flexible I have added the ability to set a filter on the customer table. In my example I will only send customers that are not Blocked for All.
Every evening the job queue sends out all the customers as you have configured.
As long as you configure everything in English, the system will run perfect. But what if your administrator has configured everything with the NAV Client loaded in Dutch?
