NeedDataSource method and I am struggling creating Row Groups.

First of all, can you confirm that this is a reasonable way to approach this problem:

My Sproc returns data similar to this:

Task #, Task Name, Qualification Method

The relationship between Tasks (# and name) to Qualification Methods is 1 to many. Meaning I have multiple Qualification methods per Task. So, what I want to do is have a single row for each task, then the next rows are the Qualification methods for a given task.

What I want it to look like is this:

Task #    Task Name
1.0           Evaluate Assembly Line Safety
                
                Qualification Methods
                Assembly Safety 101 Class
                Assembly Safety 201 Class
                Assembly Safety Certification

Task #    Task Name
2.0           Supervise Assembly Line
                
                Qualification Methods
                Supervisor Assembly Line 101 Class
                Supervisor Assembly Line 201 Class
                Harassment Class
                Supervisor Assembly Line Certification

etc.

The data comes in like this:

1.0    Evaluate Assembly Line Safety    Assembly Safety 101 Class
1.0    Evaluate Assembly Line Safety    Assembly Safety 201 Class
1.0    Evaluate Assembly Line Safety    Assembly Safety Certification
2.0    Supervise Assembly Line             Supervisor Assembly Line 101 Class
2.0    Supervise Assembly Line             Supervisor Assembly Line 101 Class
2.0    Supervise Assembly Line             Harassment Class
2.0    Supervise Assembly Line             Supervisor Assembly Line Certification

So, I thought about having a table, creating another Parent Row group to hold the Task data and then use the Detail group to hold the Qualification Methods data. I think that is a reasonable approach, but I am open to suggestions.

So, that is what I have attempted to do, but ran into some problems. When I drag a table control onto my report layout page, it automatically creates a Detail Group. I select the entire table, then select the (detailGroup) down in the Row Groups section, then right click to add a parent group. The Table Group dialog comes up and you have to create a new expression etc. I do not have any fields available to me as I do not have any data sources associated with the report. So, I just try to type in my field like this: "=Fields.Tasknumber" and another column gets created on the far left and moves the detail columns to the right. Also, no Parent Group gets created. I am not sure what it is trying to do, but could use some advice.

Thanks, Mike

Update:
After struggling with this some more, it looks like the tool is trying to create a parent group based on the detail group cells you select. I still dont quite get it, so if someone could walk me through creating a table from scratch with the appropriate parent/detail groups based on the above scenario, that would be great. I have read through all of the KB articles, documentation and related Forum posts and it seems like I almost get it...

Thanks again, Mike
