Biztalk Map Interview Questions And Answers

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.

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

Yes, but only inside Orchestrations! This type of maps must be created using the Transform shape within an Orchestration.

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.

BAM is used to monitor business milestones and key metrics in near real-time throughout a process in BizTalk.

☛ 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

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.

Yes. And the only place that map can be created with multiple schemas is in a Transform shape within an Orchestration.

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.

☛ Receive Port,
☛ Orchestration,
☛ Send Port

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.

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.

☛ 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.

The user needs to be a member of the hot group or isolated host group (assuming a default installation).

Yes. But to do so custom XSLT is to be provided to the map.

Yes, but you need to create these kind of maps inside Orchestrations only! This type of maps must be created using the Transform shape within an Orchestration. Orchestration Editor creates an envelope schema which includes all nested message schemas. Once created you can use this map on ports as well.

There is no limit, it depends on the requirement and complexity of the map.

BizTalk Server Administrator

.btm is a BizTalk Server map file.

Yes, it can be done, by creating a new schema which will contain fields for capturing values from Orchestration variable and with the help of LoadXml to load the values. This schema can be used along with an other source schema and mapping can be done. The variable also can be passed inside the Assign shop in an expression.

There is no limit.

No. As everything which we see in Map grid (links, functoids) are overwritten when external XSLT is used.

Direct binding has three types: direct to message box, self correlating, and partner ports.

Yes. Right click the map to debug and select "Debug Map".

No it is not possible to use the untyped message in the map
