1⟩ Tell me is it possible to have a map with 1 incoming message to n outgoing messages?
Yes, but only inside Orchestrations! This type of maps must be created using the Transform shape within an Orchestration.

35 Biztalk Map Questions And Answers
2⟩ Explain me what are maps?
Maps are graphical representations of XSLT (Extensible Stylesheet Language Transformation) documents that allow us to perform, in a simple and visual manner, transformations between XML messages. A map file basically is the XML file that defines the correspondence between the records and fields in one schema and the records and fields in another schema. You create a map when you want to transform or translate data that you receive or send from one schema to another.
3⟩ Tell us can we have map chaining on ports?
Not on the same port, only the first that matches the received message type will execute. You can have a map execute on a Receive Port and then have another map execute on the Send Port or have multiple maps in an Orchestration
4⟩ Tell us is it possible to link the output of a functoid placed on the right side of the map grid with a functoid placed on the left side of the map grid?
No, it is not possible as grid follows left to right precedence. An output link of the first functoid has to be placed into an input of the second functoid.
5⟩ Explain me when working with Schemas, Maps, Pipelines, and Orchestrations how should the projects be structured?
☛ Schemas and Maps in its own project
☛ Or Schemas and Maps together in its own project
☛ Orchestrations in its own project
☛ Pipelines in it own project
6⟩ Do you know what is BAM used for?
BAM is used to monitor business milestones and key metrics in near real-time throughout a process in BizTalk.
7⟩ Please explain what are grid pages and how many can we have?
The mapper grid plays a critical role in the definition of maps, containing the links and functoids that control how data in a source instance message is transformed into an instance message that conforms to the destination schema.
The grid view can have multiple layers, called grid pages, allowing you to organize complex maps into logical subdivisions of mappings. BizTalk 2010 no longer has the limitation of 20 grid pages that exist in the previous versions of the product.
8⟩ Do you know what is the difference between a Distinguished field and a Promoted Property?
☛ Distinguished fields are light weight and can only be used inside an Orchestration.
☛ Promoted Properties are defined inside a property schema, are tracking in SQL, can be tracked in HAT, and can be used for content based routing.
9⟩ Tell me what group does a user need to belong to in order to submit messages to the message box?
The user needs to be a member of the hot group or isolated host group (assuming a default installation).
10⟩ Tell me is it possible to generate XSLT from the map?
Yes, right click the map and select Validate Map. The output window will include "The output XSLT is stored in the following file:" and the location of the XSLT file.
11⟩ Tell us is there a way to add custom logic required in a Map?
Yes, it's possible and it can be done with the help of Scripting functoids or creating the custom functoids.
12⟩ Please explain where are transformations more flexible?
Transformations are more flexible and fast when they are executed from a send or receive port. We can replace map on the ports without any development effort. But if we replace map in orchestration we have to recompile and redeploy the orchestration assembly.
13⟩ Tell us is it possible to have a global variable in a map?
Yes. The choosing inline code allows us to declare global variables outside the method declaration. These are accessible throughout the map from within all inline code scripting functoids.
14⟩ Tell me why should pages to be added to Map Grid if all can be done on a single page?
Multiple pages enable you to organize your links so that any one page does not become too cluttered and confusing.It is also very helpful to label the pages and the links.
15⟩ Tell me what is the Rules Engine?
Rules are used to provide highly efficient, easily changeable business rules evaluation to Business Processes. This allows rules to be changed without rebuilding and redeploying .net assemblies. The Business Rules Engine (BRE) can also be called from any .net component through the API’s.
16⟩ Do you know when installing Biztalk and SQL on a Windows XP SP2 Desktop, what pre-requests are required?
A Lot. The best answer something like I have a custom written installation document I use or I always referrer to the most current updated installation guide from Microsoft.
17⟩ Tell me what are the places map can be used?
☛ Receive Port,
☛ Orchestration,
☛ Send Port
18⟩ Tell us is it possible to have map with n incoming messages to 1 outgoing messages?
Yes. And the only place that map can be created with multiple schemas is in a Transform shape within an Orchestration.
19⟩ Tell us is it possible to override the mapping of Mass copy?
It can be done on line by line basis. Example a field need to be passed a current date, then have the Date functoid placed a link to destination field this will override mass copy.
20⟩ Tell us what kind of transformation can we accomplish using maps? [Controversial]
Using maps he can accomplish Semantic Transformations. This type of transformation usually occurs only in BizTalk maps but also can be performed inside pipelines. Here the document maintains the same syntax that is represented (XML), but changes its semantics (data content). This type of transformation is typically one-way, since that's when we added and aggregate small parts of the information, that compose the document into another differently document, we may miss important details of its reconstruction.
