I know it's old technology (ancient now), but it's what I have to work with due to work.
I am able to create a Group and report and link it to a textbox to provide a collapsible report, with master data and detail data.
What I want to know, is it possible in SSRS2005 to create another sub-group to the first group?
i.e. Master record -> Detail -> Sub-details
Every time I try and add another detail row for example I only get one row of data in the sub-group, because it's tied to the Details Grouping. I cannot explicitly say "report grouped by this other subgroup" (where it offers you to create groups in the Group list).
Yes I am trying to do this in a table.
This is what I am after...
[+] Col1 Col2 Col3 Col4
[+] data data data data
Col1 Col2 Col3 ...
data data data ...
...
...
The [+] is what I want to set up to allow the expansion of another group within the first group.
The answer is not to try and pack too much into one reporting object. In this case the Table object.
I managed to have far more flexibility by placing the tables and fields inside a List object.
Try these...
Note: For this to work you need a query that have as much as the master and detail data inside as ONE query, so obviously your master data will repeat as deep as it has to, to get to the lowest common dataset, which in my case was the action items per student.
The List object will act as the Master data reference for all your other objects inside of it.
Now you can play! Drop in a few textboxes to show the data for the master data you want to only show ONCE per "logical record". I'll let you ponder what that meant!
Now to show subgroups, you'll need Tables for each one. Drop a Table object
In each table (group) don't specify a dataset, as I said above, all the data comes from the List.
But for each table, you'll need to define your Details Grouping. Go ahead and simply state the group parameters you require for the sub-group. So in my case, I want to display ONE row of Students, but any amount of Actions each student has. So place a StudentID for the student and an ActionID for the actions as a combined grouping.
Repeat the above for any other groups, and define their groupings so you don't get repeatitive data. One table could only have one pivot or group, so just define the index for that inside the Details Grouping. Do not use the Add.. feature to add groups, because you'll be adding groups within subgroups and go into another level again! Beware.
I hope this made sense.
