Display selected values of multi-value parameter in tablix rows - reporting-services

I am designing a report for SSRS. I want the user requesting the report to be able to specify, when they generate the report, from a pre-defined selection some values which should be displayed in a tablix on the report.
I have therefore created a multi-value parameter and populated the Available Values with the options I want the user to be able to select from, and, as expected, when the report is generated the user is able to select one or more of these values.
However, what I now want to do is include a tablix in the report, and display a row for every value in the multi-value parameter that the user selected, with the value displayed in the first cell of the row.
If the values were coming from a data table this would obviously be easy. I've also found answers on how to show all of the selected parameter values in a single textbox using the JOIN function, but I don't want to do that.
The only solution I can think of is to replicate the list of available values in the multi-value parameter in a tablix manually, and link the visibility of each row of the tablix to the selected state of the corresponding value in the multi-value parameter, but that's not very elegant and increases the effort involved in maintaining the report definition.
Any ideas on how to do this? I know the selected values from the parameter simply form an array, but I can't see how to bind a tablix to any data that isn't in a dataset, or how to create a dataset from the parameter values.

Considering that a tablix sources from a dataset, I did some experiments to see how to create a low maintenance solution for you.
Option 1: Create a data set with hard-coded options to match your multi-value parameter and select those options WHERE they exist in the parameter.
Example:
SELECT val
FROM (
SELECT 'opt1' as val
UNION SELECT 'opt2'
UNION SELECT 'opt3'
UNION SELECT 'opt4') a
WHERE val IN (#Param)
Thoughts: easier to maintain than visibility on a table, but still two hard-coded places within the report.
Option 2: Create a dataset that selects the multi-value parameter and splits it by each value. This was my first idea, but I ran into some issues with determining how to actually select the multi-value without a syntax error. I came up with a method that creates a deliminated string in the report and than parsed that string back into rows in the dataset:
Step 1) Within the dataset properties, on the parameter tab, join the multiple values together with a JOIN expression
Step 2) Create a simple query which uses the new SQL Server 2016 function string_split. Note that your database compatibility level MUST be 130 or higher to use this function (SQL 2016+). If this isn't your scenario, there are many string split functions that you can find on Stack Overflow to achieve the same thing.
Fun problem!

Generate 1 report based on multiple executions of stored procedure (passing different parameters to same procedure)

I have a SSRS report that takes a parameter and executes a stored procedure to generate a report with it.
the parameter is a values from a table that I have user select from a dropdown
let's say 15 options that are passed as parameters to each execution.
AAAA
AAAB
AAAC
...etc
is there any way I can setup the report so it will execute with each parameter and generate a report?
the issue is that now the user has to manually select 1st parameter, generate the report and then export the file result to excel.
what I want to do is a way for the user to select multiple parameters and export just one file containing all of them (the stored procedure can't take more parameters because of the way is coded depends on receiving one parameter only)
so it would have to schedule multiple executions of the stored procedure to create the report and then export this. is this possible? (as a note, the amount of parameters will change frequently so I need to give the option of selecting multiples from a list that is populated from a query to database)
and to clarify, the Stored Procedure needs to take only one parameter, this is not to be solved by sending multiple parameters to operate by using a splitter or similar, as the parameter received by the SP is used in calculations depending of order, (to not go into detail with the SP, just need to take one parameter per execution)
As you already have a report that handles a single option then you can do this easily using sub reports. Don't worry about the length of this answer it actually quite simple.
I would make a copy of the existing report to be safe....
Change the existing report to only accept a single parameter value if if doesn't already. Save this report, this will be your sub-report so let's say it's called mySubReport
Next create a new blank report.
Add a dataset (called say dsParameterList) that will give you the list of options you want the user to choose from (I guess this will be the same as your current report?). For example if it was a list of companies it might look something like SELECT CompanyID, CompanyName FROM myCompanyTable
Next add a parameter called say #options, make sure it is set to be multi-value and set the available values to use a query and point this to dsParameterList. Set the value and label fields as required.
Now create another dataset called dsLoop for example. This dataset will contain a list of selected parameter values. Using the company example from earlier the dataset query might look something like this. SELECT CompanyID, CompanyName FROM myCompanyTable WHERE CompanyID IN (#options)
Next add a table to your report and remove columns so that only 1 remains. Set the dataset property of the table/tablix to dsLoop. This means we will generate 1 row for every selected parameter value.
In the detail row right click in remaining textbox and choose 'Insert Subreport'. Now right-click the subreport placeholder and set the properties to point to the report we saved earlier (mySubReport in this example).
Whilst still in the sub report properties, click the parameters tab and add a new entry, choose the parameter in the left column and set the value in the right column to be the value from dsLoop that you want to pass to the subreport. In our company example this would probably be [CompanyID]
That's it. You run the report and choose from the parameter list, when you click View Report the dsLoop query runs and gives us a list of just those selected Companies, the report body is generated with a row for every row in the dsLoop dataset which in turn runs the subreport with a different parameter passed in each time.
Optionally You can right-click the rowgroup under the main design window and set the 'pagename' property to a value. In the Company example this might be =Fields!CompanyName.Value. When the report is exported to Excel each sheet in the workbook will be named with the name of Company

SSRS Create As Many Tables As Needed (Using One Dataset) Based on a DataSet Field

I have a query that returns relevant data about inspectors and how long it takes them to respond to issues. The only parameters are a BeginDate and EndDate so for any given date range there could be anywhere from 0 to 100 inspectors.
I am using only one dataset and it contains an "Inspector" field that I'm hoping can be used as a filter to create as many tables as there are inspectors.
I know you can set filters on tables but from my (limited) SSRS knowledge, you must already have the tables created and the filters are typically hard-coded. What I need, is some way for the report to see how many Inspectors there are in the dataset and group those records into their own tables, repeating the same one created tablix over and over as needed.
This is being done strictly in SSRS 2012, not using a ReportViewer where back-end code could help me out unfortunately...
I don't have any code examples to provide, like I said I know you can do filtering but I am at a loss when it comes to doing something like this dynamically based on data... Sorry.
Depending on the report design you could either...
Single report with grouping
1. Create a single tablix.
2. Create a row group by Inspector and then add whatever fields you need to the details section.
3. You can optionally set page breaks between instances of your Inspector rowgroup from the rowgroup properties.
Sub report method
1. Create a subreport that accepts a parameter (InspectorID for example).
2. In the subreport filter the dataset using the parameter passed in so it only return data for a single inspector.
3. Add whatever controls you need to the report to handle a single Inspector
4. Create a main report
5. Add a dataset that gives you a simple distinct list of Inspectors, this will be used to pass parameters to the subreport.
Lets assume it just contains a list of InspectorIDs.
6. Add a list control to the report and set it's dataset property to the dataset that contains your list of InspectorIDs
7. Right-click in the list control's 'cell' and insert a subreport.
8. Set the subreport property to the subreport you created earlier and set that parmameter IsnpectorID to your InpsectorID field.
This will produce a subreport for each instance of inspector it finds.
Sorry about the format of this answer, in a rush!

Add filter option on each column of the data displayed in SSRS

I am generating a table in SSRS based on the selection made by the user on two filters: Filter1 and Filter2 (say). The table so displayed has 10 columns and I wish to add filter option listing all available values for that column for all 10 columns.
Basically, I am trying to replicate the Excel functionality of filtering down data on each and every column.
Please note that I tried creating a new data set and a parameter taking all distinct values for a particular variable. However, I am still not able to get the desired results by filter the tablix on that parameter
Is there a way I can do that?
You'd need to make a new dataset that is a smaller version of your main dataset. It would need to return all potential values for the column(s) you want to filter in a single column to be used in a parameter.
Without seeing the design of the report or the dataset itself it's quite hard to be more specific.

How to group parameter values in SSRS

I currently have a few parameters set up in my SSRS report, but one is kinda giving me a bit of a headache.
I currently have a parameter called PARAM_ONE which is populated by a Dataset that I have. The value is populated the Id field of my Dataset and the label is the TextValue field of my Dataset.
I have another parameter called PARAM_TWO which is populated by a Dataset that is filtered based off of what is selected from PARAM_ONE. Again the Parameter value is populated by the Id field of this Dataset and the label is the TextValue.
My issue is that this Parameter shows duplicate fields because of the way that the data is set up. There are multiple values that go to the corresponding data I am trying to display. I would like to set it up to group all of my PARAM_TWO data that way duplicates are not showing, but I still need that first dataset relationship to map the data.
I hope this makes sense, and someone can help. If I am not making sense and need to clear anything up I would be more than happy to, just let me know.
I was able to figure out the solution to my issue thanks to the help of #user3340627.
In my dataset I created a query that looked something like this:
SELECT DISTINCT Id, TextValue FROM MyTable
WHERE SecondId = #PARAM_One
This created a parameter in the Parameters tab called #PARAM_ONE. I was then able to map my report parameter to the query parameter and run it with no issues.

How to Pass Selected Values in Multi-Value parameters to a subreport in SSRS 20008 R2

In my outer report, the one that the user runs, I just have a list with only 1 thing inside: a subreport.
The subreport takes a UserId and calculates a few stats using 4 different tablixes and datasets.
What I want the outer report to do is present the user with a list of UserIds as a multivalue parameter, and pass the selected values to the subreport.
However, what is doing is to pass ALL possible values to the subreport resulting in long delays, hundreds of pages and unwanted data.
What am I doing wrong?
Thanks.
I suspect one issue is the userid parameter has default values from the initial setup/query automatically setting the userid to all possibilities?
Also, the sub report should also have the same parameter as the outer one. Ensure this is also a multi-select but hidden and has no default values.
Then on the sub report properties you can set the userid parameter property to the main one.
I just set a filter of the values in the dataset that pulls all UserIds to be IN the paramter with the user selection.
