Lesson 1-8: Annotate and format the Lesson 1 package
Applies to: 
SQL Server
SSIS Integration Runtime in Azure Data Factory
Now that you've completed the configuration of the Lesson 1 package, it's probably time to tidy up the package layout. If the shapes in the control and data flow layouts are different sizes, or not laid out evenly, the package may be more difficult to understand.
SQL Server Data Tools provides tools to easily format the package layout. The formatting features include the ability to make shapes the same size, align shapes, and change the horizontal and vertical spacing between shapes.
Another way to improve the understanding of package functionality is to add annotations that describe package functionality.
In this task, you use the formatting features in SQL Server Data Tools to improve the layout of the data flow and also to add an annotation.
Format the layout of the data flow
If the Lesson 1 package isn't already open, double-click Lesson 1.dtsx in Solution Explorer.
Select the Data Flow tab.
To select all the data flow components at once, use Edit > Select All.
On the Format menu, select Make Same Size, and then select Both.
With the data flow objects selected, on the Format menu, select Align, and then select Centers.
With the data flow objects selected, on the Format menu, point to Vertical Spacing, and then select Make Equal.
Add an annotation to the data flow
Right-click anywhere in the background of the data flow design surface and then select Add Annotation.
Enter or paste the following text in the annotation box.
The data flow extracts data from a file, looks up values in the CurrencyKey column in the DimCurrency table and the DateKey column in the DimDate table, and writes the data to the NewFactCurrencyRate table.
To wrap the text in the annotation box, place the cursor where you want to start a new line and press Enter.
If you don't add text to the annotation box, the box disappears when you click outside it. Because of this behavior, if you want to paste text in the annotation box then copy the text to the clipboard before selecting Add Annotation.
