SSRS Reporting Framework in AX 2012

SSRS Reporting Framework in AX 2012

We will start with understanding basic concepts in Reporting Framework to examples.

Reporting Framework Terminologies

As you all know, the reports in AX 2012 have moved to SSRS reporting, so MS has introduced a robust reporting framework wrapping over the basic SSRS reporting functionality. There are many terms used in reporting framework in AX that I will try and explain here:

·         Report Definition Language: RDL is an XML application primarily used with Microsoft SQL Server Reporting Services. RDL is usually written using Visual Studio. AX has Report Definition Language Contract classes that can generate and build the RDL for an AX SSRS report. This contract provides a weakly typed representation of parameters. It contains methods that can be used to get or set values. It also contains a map of parameter names and the SrsReportParameter class. The base class is SrsReportRdlDataContract.

·         Report Data Provider (RDP): A framework that helps in building, processing and rendering data to reports. Most of the reports require RDP classes that help in implementing business logic required to process data and provide data in readable, presentable and required formats design. The base class is SrsReportDataProvider. This class has two main sub classes,SrsReportDataProvderBase and SrsReportDataProviderPreProcess. We will discuss about these classes in future posts.

·         Report Data Contracts: The Report Data Contracts framework is used to provide and manage the parameters to an SSRS report. The report data contract contains all the other relevant instances like Report Data Provider contracts, print contracts, RDL contracts and query contracts that will be used by a report.

·         Printing Contracts: The framework that manages report printing (to different mediums). The base class is SrsPrintDestinationSettings. There are other supporting contracts that are used for printing, we will discuss about them in future posts.

·         Query Contracts: This framework manages the queries used to process report data. This framework is also responsible for providing dynamic filters (similar to our ‘Select” buttons on report dialogs that open the Query specification form to filter data on report queries).

·         Report Controllers: Report controllers control the report execution and dialog forms. Report controllers can be used to modify report dialogs, validate report parameters and other validations necessary before report execution. The base class is SrsReportRunController. Reports utilizing report controllers can only be used for printing data on client side. Reports controlled by controllers cannot be used in Enterprise Portals.

·         Report UI Builders: UI Builders are used to modify the report dialogs at run-time or to add additional parameters and write custom business logic to report dialogs. Ex: You want to perform some task based on data modified for one parameter, that affects other parameters or build a custom lookup etc (something that was provided by RunBaseReport framework class in previous versions. The base class is SrsReportDataContractUIBuilder
