SSRS:Two sub Matrix Col Values addtion

1. Grouping and Filtering:

   • Ensure your data is properly grouped by Category and Region.
   • Use IIf to filter data for specific regions.

2. Dynamic Calculations:

   • SSRS expressions are evaluated at runtime, so the calculations will dynamically update based on the dataset.

3. Totals and Aggregations:

   • Use Sum() for aggregations and ensure the scope of the calculation matches your grouping.

Detailed Expression Breakdown

Filtering Data for Region A:

Sum(IIf(Fields!Region.Value = "Region A", Fields!Sales.Value, 0))

• This sums up the Sales values only for rows where Region equals "Region A".

Filtering Data for Region B:

Sum(IIf(Fields!Region.Value = "Region B", Fields!Sales.Value, 0))

• This sums up the Sales values only for rows where Region equals "Region B".

Adding the Two Sums:

=Sum(IIf(Fields!Region.Value = "Region A", Fields!Sales.Value, 0)) 
 + Sum(IIf(Fields!Region.Value = "Region B", Fields!Sales.Value, 0))

• This combines the totals for Region A and Region B.

Steps to Add Column Values of Two Sub-Matrices

Step 1: Organize Your Data

Ensure your dataset contains all the necessary fields for grouping and calculations. For example:

• Category (e.g., Product Category)
• Region (e.g., Region A, Region B)
• Sales (e.g., Sales Amount)

Step 2: Create the Sub-Matrices

1. Add a Matrix control to your SSRS report.
2. Group the matrix by Category (row group) and Region (column group).
3. Place the Sales field in the data cell of the matrix.

This will create a table-like structure where:

• Rows represent Category.
• Columns represent Region.
• Cells contain the Sales values for each combination of Category and Region.

Step 3: Add Totals for Each Sub-Matrix

1. Right-click on the Region column group in the matrix and select Add Total .
   • This will add a total row/column for each region (sub-matrix).
2. The totals will display the sum of Sales for each Region.

Step 4: Add a Combined Total Column

To add the column values of the two sub-matrices:

1. Add a new column to the matrix outside the Region group.
2. Use an expression to calculate the combined total for each Category.

The expression for the combined total might look like this:

=Sum(IIf(Fields!Region.Value = "Region A", Fields!Sales.Value, 0)) 
 + Sum(IIf(Fields!Region.Value = "Region B", Fields!Sales.Value, 0))

Explanation:

• IIf(Fields!Region.Value = "Region A", Fields!Sales.Value, 0) filters the Sales values for Region A.
• Sum() calculates the total for the filtered values.
• Repeat the same logic for Region B.
• Add the two sums together to get the combined total.

Step 5: Format the Report

1. Label the new column appropriately (e.g., "Combined Total").
2. Apply formatting (e.g., currency, alignment) to make the report visually clear.

You have two sub-matrices (e.g., grouped by categories) in your SSRS report, and you want to:

1. Calculate the sum of column values for each sub-matrix.
2. Add the corresponding column values from both sub-matrices.

For example:

• Sub-Matrix 1: Sales for Region A
• Sub-Matrix 2: Sales for Region B
• Goal: Add the sales values for each category (e.g., Category 1, Category 2) across both regions.

To add the column values of two sub-matrices in SSRS (SQL Server Reporting Services) , you can use expressions to perform calculations dynamically. SSRS allows you to work with data from multiple datasets or groupings within a single report, making it possible to calculate sums for specific subsets of data.

It is either you create a report variable for each value you want to add.Set the variable values in each sub-matrix an d then reference these variables in an expression where you need the sum.

Or, you can add custom code to your report :

Public Dim Value1 As Double
Public Dim Value2 As Double

Public Function GetSum() As Double
    Return Value1 + Value2
End Function

Set the values in each sub-matrix:

=Code.Value1 = Fields!YourField.Value

Display the sum where needed:

=Code.GetSum()

Another alternative,  if both sub-matrices use the same dataset:

=Sum(Fields!ValueField.Value, "DataSet1")
