You will not only learn the basics of NAV programming, but you will also be exposed to the technologies that surround the NAV system such as .NET programming, SQL Server, and Web Services.The first half of the cookbook will help programmers coming to NAV for the first time by walking them through the building blocks of writing code and creating objects like tables, forms, and reports. The second half focuses on using the technologies surrounding NAV to build better solutions. You will learn how to write .NET code that works with the NAV system and how to integrate the system with other software applications like Microsoft Office or even custom programs.

    "Last Date Modified" := TODAY;
    MODIFY;
    
  5. Save and close the report.

How it works...

A Data Item is a record variable. However, instead of us writing our own code to loop through each record, this functionality is built into a report. That makes a report a great place to perform a mass processing of records. For this type of report we don't want any pages to be displayed. This slows down the processing speed dramatically. To do this we set the ProcessingOnly property of the report to Yes.

The OnAfterGetRecord trigger is fired after each record is retrieved from the...
