SSRS grouping on multiple tablix

Question

I have main report that has around 10 tablix and one sub report that has 2 charts. I want the each tablix grouped by same column, but every table uses different datasets. By using List control, we can group the tablix and set a page break between each group. For that, list dataset and tablix dataset must use the same dataset name.But I am not sure how to do that for multiple datasets. Could anyone please help me how to group multiple tablix based on same field value.Is it possible using list to do that? TIA Attached for reference . Each tablix uses different data sets.but the field names are same.If Service_line column has 10 rows, then I want to display in 10 pages(one page per service line).If I select page break at each tablix, first tablix splits by that field name,after that next tablix starts to split by that field name. I want to show A/R,cash,Adjustments in one page per service_line field and then next page the same tables but different service_line. So I thought Put in List all tables together and grouping at List level will solve the problem.Could you please help me on that? or if you have any other suggestions please let me know. I am not sure how to get this done. Appreciate your help.

Answer 1

If I understood you correctly, what you want to do is modify your data a little and use nested grouping.

Combine your datasets into one dataset using unions and label each row with column 'Category'that has value ('A/R', 'Cash', 'Adjustments')

for example your dataset might look something like this

CATEGORY    | SERVICE_LINE | Total  | ...
-------------------------------------
A/R         | A            | 100
A/R         | B            | 10
A/R         | C            | 1000
Cash        | B            | 50
Adjustments | B            | 100
Cash        | A            | 5
Cash        | C            | 400
Adjustments | C            | -100
Adjustments | A            | 9999

after that you will create a 1 tablix (forget about the lists). And inside that tablix you will create a row group for Category and merge all columns and set value for the cell as [CATEGORY]. Also for this row group you want to set Page Break options as "Between each instance of a group". After that create a row below that contains all the column labels Service_line, Total, etc.

Now what you have to do is create one more row group as Adjacent Below and use Service_Line as group by attribute.

with some UI tweaking you can get it to look as you want.
