Dynamically Changing the SSRS Report Parameter Default Value...

I had a requirement to change the SSRS Report Parameter Default value based on some other report parameter values. Also the particular report parameter is set as Hidden.

For this requirement, I checked most of the forums, but could not find any solution. Most of the forums mentioned it is not possible since SSRS Report Viewer is not behaving like a Web Form and it is static.

But I was able to find an alternative approach for my requirement using the below steps.

Initially I set the default value for the report parameter using the Specify values option in the Default Values section. In the expression, I checked the relevant report parameter values and set the value.
But the issue I faced was, when I view the report by changing the parameter values, default value of the required parameter did not change and it was the initial default value.

To avoid this issue, what I did was, I created a data set and used the same condition inside the data set query and retrieved the value set.

Then assign that data set for the parameter, Available and Default values.

This works for me and each time when the relevant report parameters get changed, the default values of the required parameter also get changed.

I hope this will be useful...

Get Period N data in MDX...

In some scenarios, we may need to get Period N data including the current period.
As an example if we select the Year as 2017, we may need to get the values for 2017, 2016, 2015, .., (2017-(n-1)).

I was able to achieve it using the below MDX Query

WITH
SET [Set_PeriodRange] AS
{STRTOMEMBER(@Param_Period+".lag(N-1))" : STRTOMEMBER(@Param_Period)}

SELECT NON EMPTY{[Measures].[Sales]} ON COLUMNS,
NON EMPTY([Set_PeriodRange]) ON ROWS 
FROM [SalesCube]

Here what I did was I created a set for the what ever the required period range, using the lag function.
Then use that Set for the Row axis in the MDX.
@Param_Period is the parameter with the Year value.

The use of the created Set is that if you pass the parameter value based on a hierarchy, it will return the members for the current level of the hierarchy.
If the current level is Quarter, it will return the N number of Quarters.

Hope this will be helpful...

Hide SSRS Report Items while exporting...

While exporting to PDF, EXCEL or any other format in SSRS report, we may need to hide some images or some contents of the report.
We can set the Visibility of that report content using the below expression for the "Show or hide based on an expression" option

=IIF(Globals!RenderFormat.Name="EXCEL" OR Globals!RenderFormat.Name="PDF", true, false)

Here I just set the visibility for EXCEL and PDF format only, but you can add other formats as well.

Also please note the if it is not working for render format value as "EXCEL", check it with Globals!RenderFormat.Name="EXCELOPENXML"

How to get the Last Month value of a Measure for a Period in MDX...

There was a requirement to show only the last month value for a particular measure, for the given period.
If the period is 2016, then it show the measure value of the 2016 Dec.
If the period is 2016 Q3, then the measure value has to be 2016 Sep.

I was able to achieve it, by creating a calculated measure using ClosingPeriod function.

Formula of the Calculated Measure is as below

(ClosingPeriod([DimDate].[Year-Quarter-Month].[Month], [DimDate].[Year-Quarter-Month].CurrentMember),[Measures].[Count])

You can test it using the below MDX Query as well.

WITH MEMBER [Measures].[LastMonthValue]
AS (ClosingPeriod([DimDate].[Year-Quarter-Month].[Month], [DimDate].[Year-Quarter-Month].CurrentMember),[Measures].[Count])

SELECT NON EMPTY { [Measures].[LastMonthValue] } ON COLUMNS
 FROM [CubeName]
WHERE STRTOSET(@Period,CONSTRAINED)

Hope this will be helpful...

We couldn't complete the updates, Undoing changes in Windows 10...

I was facing the issue while restarting my laptop with Windows 10 as "We couldn't complete the updates, Undoing changes..".
I tried some of the options available in internet, but I was able to finally fix it by using the "Fix problems with Windows Update", troubleshoot option available in Windows 10.

You can do it using the below steps.

Go to the Control Panel and click on the "Find and fix problems" under "System and Security"

Then click on the "Fix problems with Windows Update" under "System and Security".

It will guide you to identify and fix the problems with the windows updates. This works for me and hope it will be useful for you as well.
