The report execution flow

The application needs to determine when to run which layout because a report can have built-in layouts (RDLC and/or Word) and custom layouts (RDLC and Word).This is handled via several codeunits that follow a report execution flow. The following figure visualizes this flow:

This flow is executed when you run a report from the application and select Print, Preview or when you run a report via C/AL code:

• First, the codeunit uses the HasCustomLayout() function to determine if the report has been set up with a custom RDLC or Word layout. If not, the default built-in layout is used.

• If the report has a custom or built-in Word layout, the MergeDocument function manages the report execution.

• If the report has been set up to use a custom RDLC layout, the ReportGetCustomRDLC function returns the custom RDLC layout as an XML string and that is used to render the report.

The Word report execution flow

When the report uses a Word layout, the execution flow is separated into two parts...
