Programming Microsoft Dynamics 365 Business Central

Tables

Design is not just what it looks like and feels like. Design is how it works.

– Steve Jobs

The competent programmer is fully aware of the limited size of his own skull. He therefore approaches his task with full humility, and avoids clever tricks like the plague.

– Edsger Dijkstra

The foundation of any system is the data structure definition. In Business Central, the building blocks of this foundation are the tables and the individual data fields that the tables contain. Once the functional analysis and process definition have been completed, any new design work must begin with the data structure. For Business Central, that means the tables and their contents.

A Business Central table includes much more than just the data fields and keys. A Business Central table definition also includes data validation rules, processing rules, business rules, and logic to ensure referential integrity. These rules are in the form of properties and AL code.

Note...

An overview of tables

There is a distinction between the table (data definition and data container) and the data (the contents of a table). The table definition describes the identification information, data structure, validation rules, storage, and retrieval of the data that is stored in the table (container). This definition is defined by its design and can only be changed by a developer. The table data is the variable content that originates from user activities. The place where we can see the data being explicitly referenced, independent of the table as a definition of structure, is in Permission Sets. In the following screenshot, the data is formally referred to as Table Data:

Figure 2.1 – Permission Set showing Table Data Object Type

Figure 2.1 – Permission Set showing Table Data Object Type

The table is not the data – it is the definition of data contained in the table. Even so, we commonly refer to both the data and the table as if they were the same. That is what we will do in this book...

Enhancing our sample application

Now, we can take our knowledge of tables and expand our WDTU application. Our base Radio Show table needs to be added to and modified. We also need to create and reference additional tables.

Although we want to have a realistic design in our sample application, we will focus on changes that illustrate features in the Business Central table design that this book’s authors feel are among the most important. If there are capabilities or functionalities that you feel are missing, feel free to add them. Adjust the examples as much as you wish to make them more meaningful to you.

Creating and modifying tables

In Chapter 1, Introduction to Business Central, we created the Radio Show table for the WDTU application. At that time, we used the minimum fields that allowed us to usefully define a master record. Now, let’s set properties on existing data fields, add more data fields, and create an additional data table to which the Radio Show...

Functional table types

For this discussion, we will first divide tables into two parent categories, depending on whether they are extensible by code, or not. Let’s take a closer look.

Extensible tables

As developers, we can change both the definition and the contents of extensible tables. Those tables reside in the Base Application, Business Foundation and System Application modules of Business Central.

The following table types are included in the extensible tables category, and are part of the Base Application module:

  • Master data
  • Journal
  • Template
  • Entry tables
  • Subsidiary (supplementary) tables
  • Register
  • Posted document
  • Singleton
  • Temporary

Let’s look at these in detail.

Master data

The master data table type contains primary data (such as customers, vendors, items, and employees). In any enhancement project, these are the tables that should be designed first because everything else will be based on these tables...

Summary

In this chapter, we focused on the foundation level of Business Central data structure: tables and their internal structure. We worked our way through the hands-on creation of a number of tables and their data definitions in support of our WDTU application. We briefly discussed field groups and how they are used. We also discussed how we used pages to view and maintain the data stored in tables. We will discuss pages in more detail in Chapter 4.

We identified essential table structure elements, including properties, object numbers, triggers, keys, and SumIndexFields. Finally, we reviewed the various categories of tables that can be found in Business Central. Now, you can identify what tables are used in standard functionality, locate what properties and AL procedures are used to accomplish business logic and start to create your own.

In the next chapter, we will dig deeper into the Business Central data structure to understand how fields and their attributes are assembled...

Can I download the code files for Early Access titles? Chevron down icon Chevron up icon

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date? Chevron down icon Chevron up icon

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready? Chevron down icon Chevron up icon

We'll let you know every time there has been an update to a course that you've bought in Early Access.
