MS CRM 2016 Subscriber SSRS Internet Custom Report

Question

I have a custom SSRS FetchXmlreport "A" for the online instance of MS CRM 2016. The report has RowGroups as well as ColumnGroups, as shown below -

I use tablix here, and for the expression in the header, I format the date field (Target Month) and show the month and year. The expression in the data row counts the number of records.

Expression in datarow =IIF(CountRows()=0 OR IsNothing(CountRows()),0, CountRows())

When the report is executed, it displays the data as follows:

sub report / drill-down , ( ). , "B" , RowGroup GrpByLOB_IndividualBranches.

, "B" , , 3 BranchName, Line TargetMonth .

"A" .

"B" , "A" 3 , .

. Line - ColumnGroup GroupByTargetMonth. , , ColumnGroup .

tablix ?

Line, -
