Week 5: Codeunit Challenge - Employee Page Customizations in Business Central

 Challenge Description

In this week's challenge, we'll focus on customizing the Employee Page in Microsoft Dynamics 365 Business Central using Codeunits. The Employee Page is a central component in managing employee data, and we'll enhance its functionality by adding custom business logic and validation rules.

This challenge is based on the table and page created in week 2 and week 3

Codeunit for Employee Data Validation:

Create a codeunit specifically for validating employee data before saving it to the database. Implement functions to validate fields such as email, phone number, and age. You can also add custom business rules like ensuring the salary is within a specific range or validating the format of the EmployeeNumber field.

Codeunit for Employee Reports:

Create a codeunit to generate employee-related reports. Implement functions to calculate and display employee performance scores, generate payroll reports, or provide insights into employee demographics. This codeunit can be used to generate printable reports or export data in different file formats.

Codeunit for Employee Notifications:

Create a codeunit to handle employee notifications. Implement functions to send automated notifications or emails to employees for important events such as work anniversaries, birthdays, or performance reviews. This codeunit can help streamline communication and keep employees engaged.

Codeunit for Employee Data Export:

Create a codeunit to export employee data to external file formats. Implement functions to export employee information to Excel, CSV, or other common file formats. This codeunit can be useful for integrating employee data with other systems or for creating backups of employee records.

Codeunit for Employee Data Calculation:

Create a codeunit to perform calculations and derive additional information based on employee data. Implement functions to calculate employee age based on the BirthDate field, calculate years of service based on the HireDate field, or perform salary calculations based on predefined formulas. This codeunit can help automate complex calculations and save time for HR professionals.
