How can I create a column of running values? - sql

I have been creating reports to get use to the tools available etc.
I have come across an issue where I cannot get a column of running values to appear correctly.
I have circled the column where I want the running values to be displayed based on the values in "Min Heads" column.
I have tried this expression:
=RunningValue(Fields!DefaultValue.Value, Sum, "Tablix")
Where Tablix is the Matrix, this calculated the running values for each row. I have tried changing the scope to the row's group and dataset but haven't had any luck.
I would really appreciate it if someone could tell me what I am doing wrong and could tell me how to create the expression for the results I require.

Try setting the scope of the function to the name of the Min Heads column. So it would be something like this:
=RunningValue(Fields!DefaultValue.Value, Sum, "Min_Heads")
I think that the scopes you have tried are too wide, or simply not valid for this.

Get Sum of Data from Second Dataset in the Second Tablix of SSRS report with Report Builder

I have two different dataset which has a common value placed in two different Tablix in Report Builder tool. I want to achieve a SUM of ELEC_DATA in the second Tablix.
I have already tried using this expression.
=LOOKUP(Field!COMP_ID.value,Field!COMP_ID.value,Field!ELEC_DATA.value,"DATASET2")
The result shows nothing at all -- no errors as well.
Then I tried with custom code.
=code.sumlookup(LOOKUPSET(Field!COMP_ID.value,Field!COMP_ID.value,Field!ELEC_DATA.value,"DATASET2"))
The Result I am getting is "0".
The expected result would be the addition of ELEC_DATA like shown in the pic attached
Looks to me like you're using the LOOKUP function incorrectly. The LOOKUP function only requires 4 parameters to be used.
=LOOKUP([SourceValue], [DestinationValue], [LookedUpValue], "[SourceDataset]")
However, I'm not sure this is the best or even a viable solution to your issue. Honestly, this would be much easier if you were able to combine these two datasets into a single dataset query.
SELECT PAC2_ID, A.COMP_ID, DATE, ELEC_DATA
FROM TABLE1 A JOIN TABLE2 B ON B.COMP_ID = A.COMP_ID
From there, you can use a Grouping on the second Tablix based on PAC2_ID which removes the need for any expressions. It should sum the values automatically when you apply the grouping.
Alright Let's try something like this.
In your 2nd Tablix create one more Column let's call it "PAC2ID_Calculated".
Now for this Column we will use lookup Expression =Lookup(Field!COMP_ID.value,
Field!COMP_ID.value,
Field!PAC2_ID,
"FirstDataset")
Now what will this return in your new Column, It will return PAC2_ID for COMP_ID from first dataset and your 2nd Tablix will be something like below
Once you get this, Group it based on PAC2_ID, you will get expected Result.
You can Hide COMP_ID column.

Trying to count records in SSRS from different data sets

I have an SSRS report that combines 5 reports into one. Each report is populated from a different stored procedure. The first page is a summary that is to provide a record count from each report. I've created fields in the stored procedure that provides the counts for each individual report: phycount and nonphyscount. I'm trying to create a table similar to this:
Active comes from one data set, Initial comes from another, Recert comes from another, etc.
I've been playing around with the Lookup and LookupSet but I'm just getting errors, plus I'm not sure if that's even the right direction.
Does anyone know how to do this?
Lookup and Lookupset are more for getting specific values out of a dataset. Very useful but not necessary for what you're trying to accomplish.
You can use aggregate functions SUM and COUNT to accomplish what you want to do. The cool thing about these functions is you can actually embed IIF statements inside of them.
I'm not sure exactly how your datasets look and are named but it would be something like this...
SUM(IIF(Fields!Type.Value = "PhyCount", 1, 0), "Active")
The sum function goes through every row of your dataset and sums the values you pass to it. The iif statement checks to see if the type field in the dataset is "PhyCount". If so, it returns 1, if not, 0. Since this will happen for every row, your SUM function will return a count of each row with status active.
edit: "Active" after the iif statement specifies the name of the dataset.
EDIT AGAIN: This solution apparently does not work in SSRS 2008.

Row Number in SSRS gives random number because of grouping

In SSRS when I am grouping by the Risk Description column. So the Rank column is completely messed up. I tried expression =RowNumber(Nothing) but still - no luck
My data in SSMS looks like on a picture below.
What would be the workaround for that?
This expression made the job:
=RunningValue(CountDistinct("YourTableName"),Count,"YourTableName")

Reporting Services - Two filters on the same chart Category Group?

I have sales data that I'd like to plot on my chart. However, at a specific point in time, we had a change taking place I'd like to ensure is clearly visible in the chart, preferably by dividing the sales data (which is stored in a single SQL Server column) into two different chunks, which would allow me to then treat them as different data series.
I used to solve this in Excel by storing the post-event data in a different column (by simply dragging them to a different column), and thus I was able to treat them as a different series (the blue and green line in the chart below. The red and orange line are pre-event and post-event averages):
I'd like to reproduce this effect in SSRS, but am not sure how to tackle it. I've tried using an approach where I added two category groups, both pointing to the date-time column, and applying filters to them (one <= the cutoff date, the other >=).
I then added my sales data twice, with the idea I could somehow connect them to the individual category groups, but that does not seem possible.
Has anyone tried anything like this before, or would have a different approach to achieve what I'm trying to get?
Thanks!
I managed to get this to work, and figured I'd share how to do it.
My dataset contains a field called DATEKEY, which stores the date in the format YYYYMMDD. It's possible to use this in an expression and evaluate the date for a specific row. In case the expression evaluates to true, we display the value. If not, we display a blank string.
In case we want to show the values prior to the date, the expression would be:
=IIF(Fields!DATEKEY.Value <= 20130601, Avg(Fields!My_NUMBER.Value), "")
The second series can then be made by reversing the symbol:
=IIF(Fields!DATEKEY.Value >= 20130601, Avg(Fields!My_NUMBER.Value), "")
The graph then looks like this:

How to specify an order for the columns in a matrix?

I'm working on a SQL Reporting Services report (in VS.Net 2005) which displays a count of different data in a matrix. The columns have a count on the amount of customers in a certain set. So I have several columns like these: "1 employer", "2-9 employers", "10-19 employers" and so on.
The problem I have is that SQL Reporting Services sorts the columns in the matrix alphabetically. So I end up having the "10-19" column after the "1 employer" column but before the "2-9".
Is there any way to fix this?
Or maybe a trick to change the labels of the columns to that they sort right?
Thanks.
This can also be done by adding a new column to the query for the sort order. Then right click the column group from the matrix and select group properties. On the left hand side select sorting. From here you can specify another column to sort by instead of the column header. No custom formula needed.
We do a lot of SSRS Reports and this was always an issue with mdx. Here is one way we do it:
Set Sorting in the Grouping and Sorting Properties to sort by this expression:
=iif(Fields!DataSetField.Value = "ColumnName", "zzz", Fields!DataSetField.Value)
Where "zzz" could be a number or whatever you need it to be to help the sort and then select Direction as either Ascending or Descending base on this expression.
This may be a bit convoluted, but we had a similar problem and no means to change the SQL.
What we did was create a calculated field in the dataset that returns a number for each column and sorted the group on that number.
I had a similar problem but did not find a solution using a matrix in time - so I used a table - and put the needed logic of the matrix in my SQL-statements.
It's not the best thing to do but it works - it's fast enough and it don't takes that long to write.
I went into MATRIX --> PROPERTIES --> GROUPS.
Then, I "moved" the GROUP I wanted it to sort by UP in the list.
I went to PREVIEW, and it worked perfectly.
It even kept my column order the same.
Go to Edit Group - Sorting - Change the direction to descending for the expression.
For distinct numeric order of a Tablix use following line of code in expression.
=RunningValue(CountDistinct("YourTableName"),Count,"YourTableName")
Simply Go to tablix/Matrix Column Group and Right Click on the Group Properties then go Sorting and Delete the auto added record from Sorting.. Now your sorting will based on the Data you have added in Data set.
