Extracting Data in Master Page

A Master Page helps you to format how page looks like (page borders, orientation, margins, color and size) and to add header and footer sections on your documents.
When designing a Master Page it might be necessary to make available data attributes in contexts where normally they would not be available.

Although data attributes cannot be used inside a Master Page element, variables can be used to hold your data. To achieve this you need to use variable assignment mechanism. So first thing to do is to create a new internal variable (internal variables are used for calculations and are not displayed in the document specification). In template editor, assign a data value to the newly created variable.
Let’s say for example that you need to display the name of a DOORS module in the header section. Add a DOORS data source schema. Create a new container in template and assign the module query on the element. Once queries are assigned to template elements, all the attributes of the elements returned by the queries can be used.

From the contextual menu of container element go to Variable Assignment option and assign to our variable the module.Name attribute.

Now, _documentTitle variable will hold the module name.
In the Master Page, in the place where you want to display the module’s name, add a text element and set the variable as value.
The Master Page should be assigned to an element in document template and this element should be placed after the container with variable assignment.

This is the way that allows you to render data inside Master Pages in RPE.
