Building Custom Pages and Tables

One of the most common ways to extend Business Central is by creating custom pages and tables. These customizations can help tailor Business Central to a business’s specific workflows and data requirements.

Custom Pages: Pages in Business Central serve as the user interface for interacting with data. Developers can create custom pages that allow users to view, enter, and edit information specific to their business processes. For instance, if a company needs to track a unique set of inventory attributes, a custom page can be created to display this information in a user-friendly format.

There are several types of pages available in Business Central, including List Pages, Card Pages, and Role Center Pages. A List Page displays a collection of records, such as customers or orders, while a Card Page is used for viewing or editing individual records. Developers can also create FactBoxes and Action Pages that provide additional context and functionality directly on the page.

When building custom pages, it is important to ensure they integrate seamlessly with Business Central’s built-in pages. Using Actions and Triggers, developers can define behaviors that occur when a user interacts with a page. These interactions could include opening a detailed view of a record or triggering a workflow automation.

Custom Tables: In Business Central, a table is essentially a structure for storing data. When creating a custom table, developers must define the table’s fields (columns) and specify the types of data that each field will hold. This could range from simple text fields to complex date or boolean fields.

Once a custom table is created, developers can link it to other pages and extend Business Central’s native functionality. For example, you could create a custom table to track project-specific information, such as tasks, deadlines, or milestones, and integrate it into an existing page or report.

Creating custom tables allows businesses to store data in a way that fits their specific needs, without being constrained by the limitations of pre-existing tables. Moreover, developers can set up relations between custom tables and standard tables in Business Central to ensure that data is interconnected and that workflows are smooth.

Creating Custom Business Logic with Codeunits

Another essential aspect of extending Business Central is developing custom business logic. This is done through Codeunits, which are the objects in Business Central where you define processes, calculations, or other automated tasks.

Codeunits are especially powerful because they allow you to encapsulate complex business logic and trigger it automatically based on certain conditions. For example, a custom codeunit could be used to automatically calculate discounts based on order size, update inventory levels after a sale, or send an email notification when a specific event occurs.

Codeunits can be invoked from other parts of Business Central, such as pages, reports, or even web services. The use of codeunits in Business Central promotes modularity and allows you to maintain clean and maintainable code.

Developers can create codeunits for a variety of purposes:

Automation: Automate repetitive tasks like data imports, sales order processing, or inventory adjustments.
