Hi,
Let's breakdown this into 3 as high level, (This is the summary)
1. Create the query in AOT
2. Develop the report in VS
3. Create the UI
1. Create the Query in AOT
1.1, Add the table to query. AOT>Queries>Data Source
1.2, Add the fields to Data Source. AOT>Queries>Data Source>Fields
1.2.1, Define the relationships if you have more than one Data Source.
2. Develop the report in Visual Studio ( 4 Steps = Report/Build/Add/Deploy)
2.1, Create a new project in the VS. File>New>Project>DAX>Report Model
2.2, Create the report with Solution Explorer SE>Add>Report
2.3, Define the Properties & AX Data Set; Data Source Type=Query| Name="Name of your Query"
2.4, Create the report design and Add a Table (Drag & Drop the Data Set from the Report)
2.5, Build the report from the Solution Explorer
2.6, Add the report to AOT
2.7, Deploy the report to AX
3. Create the UI in AX
3.1, Create the Menu Output item in the AX
3.2, Apply the appropriate Menu Output Properties
Object Type = SSRS Report
Object = "Name of your report"
3.3, Select the dataset and run the report.
This is a brief summary. If you follow these steps you should be able to see your report in the AOT. You will find,
Your Query under the Query node
Your Report under the SSRS Reports node
and your UI under the Menu Output.
