Sum totals when using Calculated Members - ssas

In my SSAS cube (multidimensional) I have a measure group called Cargo. In there I have three properties:
[Contract_Key] (integer)
[Include In Sum] (integer)
[Quantity] (integer)
My Contract_Key points to my dimension Contract. Include In Sum is either 0 or 1. Quantity is a number I want to sum, if Include In Sum = 1.
My Contract dimension contains a Contract Number as well as a sub contract number. Very often my users want to group the contracts by their main contract numbers but still be able to see the individual sub contract details. Unfortunately when having both the main contract (which contains the total quantity) and the sub-contracts will add up a wrong number in the Quantity (the will double up).
So I have added a Calculated Member (for now called Summed Quantity) where the expression is:
IIF([Measures].[Include In Sum]=1,[Measures].[Quantity],0)
Being very new to MDX, my assumption is that if Include In Sum equals 1 then it will sum the Quantity and otherwise it will have the value 0.
My Contracts are all in the same dimension but there can be main contracts and sub-contracts. The way my Include In Sum is made is:
If there is only a main contract, then Include In Sum is true for the main contract.
If there are sub-contracts then set the main contract's Include In Sum to 0 and all the sub-contracts Include In Sum to 1.
My goal is to always show a quantity - either from the main contract or from the sub-contracts (which have more correct values, if they exists). My Include In Calc shows correctly in Excel - and are thereby set correct in my database.
My problem is that if a contract consist of sub-contracts, then I do see the correct values on the individual lines (main contract is blank in quantity and all sub-contracts shows the correct quantities). But my sub totals and grand totals in Excel are blank. Only main contracts which have no sub-contracts shows up correctly.
Contract No Quantity Include In Sum
100 34000 1 <==== A sub-total line - only a main contract
100 34000 1
110 4 <==== A sub-total line - main contract with sub-contracts
110 0
110-1 2500 1
110-2 2500 1
110-3 2500 1
110-4 2500 1
Of course I do not want to show the "Include In Sum" - it is just there as long as I cannot get the sub totals to work in Excel.
What I want is that my second sub-total line should give me the value 10000.
My expression does not contain a SUM function (which might be the problem). But when adding the SUM() around the above MDX expression will just make every value come out as #VALUE in Excel - again - this might be me not knowing the syntax!

How to calculate dynamic % of grand total as a measure on Power BI?

I have the below table connected into Power BI and I am looking for ways to create a formula calculating % of grand total of the Rating column and further subtracting with targets for each rating. For example, the % of grand total for Rating 1 is 3 divided by 7 (42.86%). The most important part of the formula is the denominator which has to remain at a total level and dynamic for any filters applied to either Grade or BU columns. For example, denominator at a total level would be 7 and when filtered down to Academy BU should be 3.
Sample Data Table:
Rating Target Table:
I want the end result to look like this,
I have used the following formula to achieve this,
Measure created: % of total calc = DIVIDE(COUNT('Table'[Rating]),CALCULATE(SUM('Table'[Count]),'Table'[Rating]))
To make the above formula work I had to add an extra column and include ones in it (see below)
I want to know if there are other ways of achieving this outcome?
ALLEXCEPT will produce such result to exclude used dimensions and include mandatory filters such as date with one condition, rating, date, any dimension must be in the same table.

Exclude one dimension from total count / sum in qlik

I want to have the %-Share of a value in Qlik. I have two dimension and on KPI which I am using in a distribution graph:
The data is:
Point Brand Business
A AA 1
B AA 1
C AA 1
Right now i am using the formula: Count([Business])/Count(total [Business]), on my Y-Achse I have the Brand and my point is Point, Right now he is calculating the Super total, but How can I only calculate the total for the Brand? Something like Count([Business])/Count(total [Business], if Brand == Brand)
You should add Brand field as aggregation scope
count([Business]) / Count(total <Brand> [Business])
From Qlik's documentation
By using TOTAL [], where the TOTAL qualifier is followed by a list of one or more field names as a subset of the chart dimension variables, you create a subset of the total possible values.
Adding the field to the total can be translated as: count all Business but aggregated by Brand. And since Brand is also a dimension to the chart then for each row Count Total will be the count for the current Brand value

Counting latest instance of multiple only based on filter context

I've got a large table of events that have occurred in an inventory of vehicles, which affect whether they are in service or out of service. I would like to create a measure that would be able to count the number of vehicles in the various inventories at any point in time, based on the events in this table.
This table is pulled from a SQL database into an Excel 2016 sheet, and I'm using PowerPivot to try to come up with the DAX measure.
Here is some example data event_list:
vehicle_id event_date event event_sequence inventory
100 2018-01-01 purchase 1 in-service
101 2018-01-01 purchase 1 in-service
102 2018-02-04 purchase 1 in-service
100 2018-02-07 maintenance 2 out-of-service
101 2018-02-14 damage 2 out-of-service
101 2018-02-18 repaired 3 in-service
100 2018-03-15 repaired 3 in-service
102 2018-05-01 damage 2 out-of-service
103 2018-06-03 purchase 1 in-service
I'd like to be able to create a pivot table in Excel (or use CUBE functions, etc) to get an output table like this:
date in-service out-of-service
2018-02-04 3 0
2018-02-14 1 2
2018-03-15 3 0
2018-06-03 3 1
Essentially, I want to be able to calculate the inventory based on any date in time. The example only has a few dates, but hopefully provides enough of a picture.
I've basically come up with this so far, but it counts more vehicles than desired - I can't figure out how to only take the latest event_sequence or event_date and use that to count the inventory.
cumulative_vehicles_at_date:=CALCULATE(
COUNTA([vehicle_id]),
IF(IF(HASONEVALUE (event_list[event_date]), VALUES (event_list[event_date]))>=event_list[event_date],event_list[event_date])
)
I tried using MAX() and EARLIER() functions, but they don't seem to work.
Edit: Added the PowerBI tag as I'm now using that software to attempt to solve this as well. See comments on Alexis Olson's answer.
I think I've found a much cleaner method than I gave previously.
Let's add two columns onto the event_list table. One which counts vehicles "in-service" on that date and one which counts vehicles "out-of-service" on that date.
InService =
VAR Summary = SUMMARIZE(
FILTER(event_list,
event_list[event_date] <= EARLIER(event_list[event_date])),
event_list[vehicle_id],
"MaxSeq", MAX(event_list[event_sequence]))
VAR Filtered = FILTER(event_list,
event_list[event_sequence] =
MAXX(
FILTER(Summary,
event_list[vehicle_id] = EARLIER(event_list[vehicle_id])),
[MaxSeq]))
RETURN SUMX(Filtered, 1 * (event_list[inventory] = "in-service"))
You can create an analogous calculated column for OutOfService or you can just take the total minus the InService count.
OutOfService =
CALCULATE(
DISTINCTCOUNT(event_list[vehicle_id]),
FILTER(event_list,
event_list[event_date] <= EARLIER(event_list[event_date])))
- event_list[InService]
Now all you have to do is put event_date on the matrix visual rows section and add the InService and OutOfService columns to the values section (use Maximum or Minimum for the aggregation option rather than Sum).
Here's the logic behind the calculated column InService:
We first create a Summary table which calculates the maximal event_sequence value for each vehicle. (We filter the event_date to only consider dates up to the current one we are working with.)
Now that we know what the last event_sequence value is for each vehicle, we use that to filter the entire table down to just the rows that correspond to those vehicles and sequence values. The filter goes through the table row by row and checks to see if the sequence value matches the one we calculated in the Summary table. Note that when we filter the Summary table to just the vehicle we are currently working with, we only get a single row. I'm just using MAXX to extract the [MaxSeq] value. (It's kind of like using LOOKUPVALUE, but you can't use that on a variable.)
Now that we've filtered the table just to the most recent events for each vehicle, all we need to do is count how many of them are "in-service". I used a SUMX here where the 1*(True/False) coerces the boolean value to return 1 or 0.
This is pretty difficult. I don't have a great answer, but here's something that kind of works.
You'll create a new calculated table where you'll calculate the status for each vehicle on each date. Start with the base cross join for each vehicle and each date:
= CROSSJOIN(VALUES(event_list[vehicle_id]), VALUES(event_list[event_date]))
Then add a calculated column to find the max sequence number for each vehicle on that date.
Sequence = MAXX(
FILTER(event_list,
event_list[event_date] <= Cross[event_date] &&
event_list[vehicle_id] = Cross[vehicle_id]),
event_list[event_sequence])
Now you can lookup the inventory value for each vehicle/sequence pair with another calculated column:
Inventory = LOOKUPVALUE(
event_list[inventory],
event_list[vehicle_id], Cross[vehicle_id],
event_list[event_sequence], Cross[Sequence])
The result should look something like this:
Once you have this, you can create a matrix using this calculated table. Put the event_date on the rows and Inventory on the columns. Filter out blank inventory values in the visual level filter and put the vehicle_id in the values field, using a count or distinct count as the aggregation method (instead of the default sum).
It should look like this:

counting and numbering in a select statement in Access SQL

Could you please help me figuring out how to accomplish the following.
I have a table containing the number of products available between one date and another as per below:
TABLE MyProducts
DateProduct ProductId Quantity Price
26/02/2016 7 2 100
27/02/2016 7 3 100
28/02/2016 7 4 100
I have created a form where users need to select a date range and the number of products they are looking for (in my example, the number of products is going to be 1).
In this example, let's say that a user makes the following selection:
SELECT SUM(MyProducts.Price) As TotalPrice
FROM MyProducts WHERE MyProducts.DateProduct
Between #2/26/2016# And #2/29/2016#-1 AND MyProducts.Quantity>=1
Now the user can see the total amount that 1 product costs: 300
For this date range, however, I want to allow users to select from a combobox also the number of products that they can still buy: if you give a look at the Quantity for this date rate, a user can only buy a maximum of 2 products because 2 is the lowest quantity available is in common for all the dates listed in the query.
First question: how can I feed the combobox with a "1 to 2" list (in this case) considering that 2 is lowest quantity available in common for all the dates queried by this user?
Second question: how can I manage the products that a user has purchased.
Let's say that a user has purchased 1 product within this date range and a second user has purchased for the very same date range the same quantity too (which is 1) for a total of 2 products purchased already in this date range. How can I see that for this date rate and giving this case the number of products actually available are:
DateProduct ProductId Quantity Price
26/02/2016 7 0 100
27/02/2016 7 1 100
28/02/2016 7 2 100
Thank you in advance and please let me know should you need further information.
You could create a table with an integer field counting from 1 to whatever max qty you could expect. Then create a query that will only return rows from your new table up to the min() qty in the MyProducts table. Use that query as the control source of your combobox.
EDIT: You will actually need two queries. The first should be:
SELECT Min(MyProducts.Quantity) AS MinQty FROM MyProducts;
which I called "qryMinimumProductQty". I create the table called "Numbering" with a single integer field called "Sequence". The second query:
SELECT Numbering.Sequence FROM Numbering, qryMinimumProductQty WHERE Numbering.Sequence<=qryMinimumProductQty.MinQty;
AFAIK there is no Access function/feature that will fill in a series of numbers in a combobox control source. You have to build the control source yourself. (Anyone with more VBA experience might have a solution to solve this, but I do not.)
It makes me ache thinking of an entire table with a single integer column only being used for a combobox though. A simpler approach to the combobox would just to show the qty available in a control on your form, give an unbound text box for the user to enter their order qty, and add a validation rule to stop the order and notify them if they have chosen a number greater than the qty on hand. (Just a thought)
As for your second question, I don't really understand what you're looking for either. It sounds like there may be another table of purchases? It should be a simple query to relate MyProducts to Purchases and take the difference between your MyProducts!qty and the Purchases!qty. If you don't have a table to store Purchases, it might be warranted based on my cursory understanding of your system.

Creating buckets by comparing Dimension member against Measure using MDX

I have a Product dimension with hierarchies - product_id, initial_price, product_name and Measures - units_sold, cost_per_unit, revenue_per_unit. For each product_id I need to compare initial_price against revenue_per_unit and then assign it to a bucket based on the comparison.
Consider the following example:
Input:
product_id initial_price revenue_per_unit
1 10 12
2 20 18
3 30 30
Output:
product_id bucket_name
1 Profit
2 Loss
3 Same
How can I achieve this using MDX?
WITH Member [Measures].[Bucket] AS
CASE
WHEN [Measures].[initial_price] < [Measures].[revenue_per_unit] THEN
"Profit"
WHEN [Measures].[initial_price] > [Measures].[revenue_per_unit] THEN
"Loss"
ELSE
"Same"
END
SELECT {[Measures].[Bucket]}
ON COLUMNS,
[Product].[Product Name].Members
ON ROWS
FROM [yourcube]
should deliver what you want. Please note that calculated measures need not return numbers, they also can return strings in MDX (they even can return a string for some cells, and a number for others).
In case you do not have the price available as e. g. an average price on aggregated product level, and want to do the bucketing on product level, the best solution would be not do do that in MDX at all, but in the cube design: Just calculate the bucket on the relational side, and add it as an attribute to the product dimension.
You did not state anything about other dimensions, especially time. In case some other dimensions matter as well to determine the bucket, it might be necessary to add a separate dimension just for the buckets.
