A report is made up of two parts:

• Dataset: This is an AL file where you will define the tables, fields, filtering, and logic that applies to the report.
• Layout: This will be either a Microsoft Word or an RDLC-formatted file and is where you define what the output of the report will look like.

The two parts are linked using properties in the AL file so that when the report is loaded into Business Central, the system knows which layout to use for which report.
