What is MVC?
Overview on BOF
BOF in Services
BOF in Reports
Q&A
Is MVC an architecture or design pattern?
Pros:
 Loosely coupled
 Clear separation of UI, Data and Business logic
 Test Driven
 Code Reuse
 Hide Data Access
 Adaptable to change
cons:
 Duplicated code between common views
 Not a true n-tier architecture (triangulation)
 Not a true publisher – subscriber model
The Business Operation Framework service is one of the system
services exposed by Microsoft Dynamics AX and that adheres to
the Windows Communication Foundation (WCF) protocols and
standards. Following are the features of BOF:
 Allows menu-driven execution or batch execution of services.
 Call services in synchronous or asynchronous mode.
 Automatically creates a customizable UI based on the data
contract.
 Encapsulates code to operate on the appropriate tier
(prompting on the client tier, and business logic on the server
tier).

To create a Business Operation Framework service, the following
steps must be performed:
 Create a data contract class
 Identify the parameters passed to the service
 Register the class as a Business Operation Framework service
 Optionally customize the automatically generated UI for the
class
Attribute based customizations.
Attributes are SysOperationGroupAttribute,
SysOperationGroupMemberAttribute,
SysOperationDisplayOrderAttribute,
SysOperationLabelAttribute,
SysOperationHelpTextAttribute etc.
 Code based customizations.
Using UIBuilder class. For example check
CustRecurrenceInvoiceUIBuilder Class.


Validate DataContract at design time
◦ To perform validation on contract class, you need to implement
SysOperationValidatable Interface and override the validate method.
For example of this, check CustRecurrenceInvoiceDataContract class.

Modify DataContract at run time
◦ To modify the contract at runtime, we need to create a controller class
extend from SysOperationServiceController class.
◦ Get the contract object by calling the method getDataContractObject
from controller class instance and then call the corresponding parm
methods of contract class, passing the desired values.
A Business Operation Framework service can be called in four ways:
 As a menu item
◦
◦
◦
◦
Create an Action Menu Item
Set the ObjectType to Class
Set the Object to SysOperationServiceController
Set the Parameters to <ServiceClassName>.<MethodName>

As a batch process

Synchronously

Asynchronously
◦ Create a job and create the service method in that job
◦ To run the service synchronously, edit the menu item, set
EnumTypeParameter=SysOperationExecutionMode; EnumParameter=Synchronous
◦ To run the service synchronously, edit the menu item, set
EnumTypeParameter=SysOperationExecutionMode;
EnumParameter=ASynchronous

AX 2012 report programming model is build on SysOperation Framework
In AX2012, we have 2 options to develop reports
◦ Modeled solution aka query based
◦ Code based solution aka Report data provider based
View: SrsReportDataContractUIBuilder
Model: SrsReportDataContract/SrsReportDataProviderBase
Controller: SrsReportRunController
