What goes into an MDX data cell by default? - tfs

MDX newbie here. I'm writing a query against the TFS 2015 Team Services OLAP cube to get the hang of it. So I write a query against the changesets and dates in November on a particular team project:
select non empty [Date].[Date].[Date] on 0,
non empty [Version Control Changeset].[Checked In By].[Checked In By] on 1
from [team system]
where ([Date].[Year - Month - Date Hierarchy].[Month].&[2017-11-01T00:00:00],
[Team Project].[Team Project Hierarchy].&[{00000000-1111-2222-3333-444444444444}])
I get a recordset with all people in TFS on rows, some days in Nov 2017 on columns (presumably ones when checkins took place), and some numbers in the cells. The numbers are the same in each row, but vary from one column to another.
In a query like this, where do the numbers come from? Any why are all the people in rows, and not just the ones who did the check-ins on the project? Not every person in the building has contributed to this project in November...

It's simply [Measures].DefaultMember, usually it's your first measure:
select non empty [Date].[Date].[Date] * [Measures].DefaultMember on 0,
non empty [Version Control Changeset].[Checked In By].[Checked In By] on 1
from [team system]
where ([Date].[Year - Month - Date Hierarchy].[Month].&[2017-11-01T00:00:00],
[Team Project].[Team Project Hierarchy].&[{00000000-1111-2222-3333-444444444444}])

Set new year for date column in rails query

I have the contract start of a number of companies, and I want to report on each contract year by creating a column with the contract start updated to a select year. There are a number of solutions in SQL involving functions like DATE_ADD or DATEFROMPARTS, but I'm having trouble adapting it to rails (if those functions are available at all).
The closest I've gotten is: Company.select("contract_start + '1 YEAR'::INTERVAL as new_contract_start"). This adds 1 year to each contract start but doesn't take into account contracts older than a year (or started the same year). I've also tried the following but again run into syntax errors:
new_year = 2020
Company.select("contract_start + '#{new_year} - EXTRACT (YEAR from contract_start) YEAR'::INTERVAL")
I'm looking for a solution that can either:
Directly set the year to what I want
Add a variable amount of years based on its distance from the desired year
I'm on Ruby 2.3.3
I think the key here was finding functions compatible with the PostgreSQL that my database was built on. Once I started searching for the functions I thought would help and their PostgreSQL equivalents, I found more compatible solutions, such as: NUMTODSINTERVAL in PostgreSQL
I ended up with:
contract_start_year = 2020
Company.select("contract_start + make_interval(years => CAST (#{contract_start_year} - EXTRACT (YEAR from contract_start) as INT))
I've also made it a bit smarter by adding the number of years required to get the latest contract date without going over the report date. This would be problematic if the report start date was "2020-01-01" but the contract start was "2017-06-01". Setting the contract date to "2020-06-01" would overshoot the intentions of the report.
report_start = "`2020-07-01`"
Company.select("contract_start + make_interval(years => CAST (EXTRACT (YEAR FROM AGE(CAST (#{start_quotations} AS DATE), contract_start)) AS INT)) as new_contract_year")
Note the additional single quotes in report_start since the SQL code need to read a string to convert it to a date
There might be other methods that can "build" the date directly, but this methods works well enough for now.

Commission calculation based on sliding month (googlesheets)

I have to pay a commission to Agents (affiliates) based on the following conditions:
the commission starts on a monthly basis following a USER (linked to the Agent) first deposit/purchase on a website
agents have a decreasing commission, ex: 1 month following first deposit of their USER = 30% of sales, 2d month period following 1st deposit of USER: 25% of sales, etc
Commission are paid on a month basis calculation (ex: from 01/07/2020 till 31/07/2020)
If a USER makes a first purchase on June 22d and if sales commission for 1st period is 30%, then agent is eligible to a 30% commission on sales from june 22d till July 22d, then 25% for sales from 23rd july till 23rd august, etc
I have designed a googlesheets (see below) that serves the purpose (using 12 columns to get the correct commission% for a specific user on a specific day!), but I am trying to find a more straight forward formula to get the applicable com. % based on the commission sliding table and the first deposit date of a specific user.
Can anyone help?
The google sheets showing my calc is here:

This might help you. (Updated to correct the row number of where the formula should go.)
If you insert a new column in your sheet, to the right of Column W, the Current Commision Month, and paste the following formula in the cell where the Current Commision Month header text should appear (Row 9 in your sample) of that column, it replicates the results in your Current Commision Month.
But it does not require columns I through V. You can test that by deleting columns I through V - you can use Undo and Redo to go back and forth, if necessary. Depending on how you use your "End" column - the logic wasn't clear to me - the info for that can also be gained in this one column.
={"Current
Commision
Month";"";ArrayFormula(
if(
($H11:H<>"") * ($A11:A>=date(year(H11:H),month(H11:H),day(H11:H))),
ifs( $A11:A< date(year(H11:H),month(H11:H)+1,day(H11:H)),1,
$A11:A< date(year(H11:H),month(H11:H)+2,day(H11:H)),2,
$A11:A< date(year(H11:H),month(H11:H)+3,day(H11:H)),3,
$A11:A< date(year(H11:H),month(H11:H)+4,day(H11:H)),4,
$A11:A< date(year(H11:H),month(H11:H)+5,day(H11:H)),5,
$A11:A< date(year(H11:H),month(H11:H)+6,day(H11:H)),6,
$A11:A>=date(year(H11:H),month(H11:H)+7,day(H11:H)),9999),
""))}
The first IF test is to check that the FirstDeposit date is not blank, and that the sale date is greater than or equal to the FirstDeposit date.
The IFS tests go through and check whether the sale date is less than one of the months, and stops at the first value (commission month) that is greater than the sale date. If never, it places a vlaue of 9999.
Note that the "9999" values are just to indicate the sale date is greater than the "End" date, and can be changed to blanks or whatever you want.

I've added a sample tab with the final result. Let me know if this helps. There may be several other enhancements possible for your sheet, in particular the use of ARRAYFORMULAS to fill values down many of your columns.
I haven't spent time on the actual commision calculations, in the final columns, but if you feel that still needs improvements, I can try to simplify there as well.

Jira filter to list ticket created between a time period of day

How to create a JQL filter to list all tickets created between 8 AM to 4 PM irrespective of created day and date?
I know startOfDay() deal with only for current day. For example , below will list all ticket created of 'myproject' between 8 AM and 4 PM of current day (as per timezone set in my user profile)
created > startOfDay("+8h") and created < startOfDay("+16h") and projecy='myproject'
My requirement is list a ticket created any day (not only current day) in my work shift 8 AM to 4 PM.
Your requirement can not be fulfilled with simple JQL queries. You could query the database directly with some SQL or you can use some scripting with a plugin (check out this post for example).
Other possibilities are to use the JIRA API to receive the ticket data and then filter the tickets which were created in the desired time frame.
Another possibility to at least get the relevant tickets from the current week with a JQL query could be to create a filter like this: created > startOfWeek(7h) AND created <= startOfWeek(17h) OR created > startOfWeek(31h) AND created <= startOfWeek(41h)... (Source)

"Join" facts and dimensions in olap cube

I have to calculate / present number of team trough years in olap cube
My team fact is structured this way:
TeamId DateFrom DateTo (FactTeams)
1 2012 2015
2 2012 2015
3 2012 2015
4 2015 2018
1 2018 2019
Cube must be able to answer, for example, how many teams have been active in year 2012 (3 teams)
I have prepared another helper fact table that contains all combination of teams id and their dates.
TeamId DateRange (FactTeamDates)
1 2012
1 2013
1 2014
1 2015
1 2018
1 2019
2 2012
2 2013
2 2014
2 2015
...and so on ...
I have created two facts one FactTeams and another FactTeamDates. I have also standard date dimension. Here is my data source view:
https://www.dropbox.com/s/5d2gzumxv5fejdq/teams.jpg
FactTeams.TeamId is linked to FactTeamDates.TeamId and FactTeamDates.DateRange is linked to DimDates.DateKey.
I have measure “Team Number” that is distinct count of FactTeams on column TeamId.
My desired MDX query output for measure Team Number on COLUMNS and Years ON ROWS is:
Team Number
Year 2012 3
Year 2013 3
Year 2014 3
Year 2015 4
My question: How to organize my fact and set dimension usage in my cube to get desired output?
SQL query that produce desired output:
SELECT
d.CalendarYear
,COUNT(DISTINCT TeamId)
FROM FactTeams zt
INNER JOIN FactTeamsDates td ON zt.TeamId = td.TeamId
INNER JOIN DimDates d ON d.DateKey = td.DateRange
GROUP BY d.CalendarYear ORDER BY 1
Note that I know that I can create data view based on the above sql query (with joins) and then have one joined fact table, but I want to have some kind of join between my cubes dimensions and facts – to have joins in cube (olap) level only, not in sql (database, or cube data view)
Thanks in advance
You can create a distinct count measure and this should solve your problem

How do I report on completed work for a given week in TFS 2008?

We're on Team Foundation Server 2008 and I'm trying to find a way to report on the change in completed work from week to week at the task level. The MDX query below works pretty well, but I'd like to get rid of need to hard code last week's date. I've tried using prevmember and parallelperiod without success, but I'm no MDX expert.
WITH
MEMBER [Measures].[Completed Work by WI on dt1] AS
(
[Assigned To].[Person].CurrentMember,
[Work Item].[System_Id].CurrentMember,
[Date].[Year Week Date].[Week].&[2008-12-07T00:00:00],
[Measures].[Microsoft_VSTS_Scheduling_CompletedWork]
)
MEMBER [Measures].[Completed Work by WI on dt2] AS
(
[Assigned To].[Person].CurrentMember,
[Work Item].[System_Id].CurrentMember,
[Date].[Year Week Date].CurrentMember,
[Measures].[Microsoft_VSTS_Scheduling_CompletedWork]
)
MEMBER [Measures].[Completed Work] AS
[Measures].[Completed Work by WI on dt2] - [Measures].[Completed Work by WI on dt1]
SELECT
NON EMPTY
{
[Measures].[Completed Work]
}
ON COLUMNS,
NON EMPTY
{
Filter(
([Assigned To].[Person].[Person],[Work Item].[System_Id].[System_Id],[Work Item].[System_Title].[System_Title]), [Measures].[Completed Work] >0 )
}
ON ROWS
FROM [Team System]
Look at the provided Work Completed report. It automatically sets one of its date fields to today minus one month.
EDIT: Just logged into my work system to double check on this. The report is actually called "Remaining Work". Go to the SharePoint portal that was created for your Team Project, and find the list of standard reports. It'll be in that list. You can export that report to file, open it in Visual Studio and see the date field logic.
EDIT2: For an MDX function to get the previous week, try a variation on this: http://social.msdn.microsoft.com/Forums/en-US/tfsreporting/thread/0a656453-eaf1-47a2-a376-cb6eaec0db51
#sliderhouserules - I took a look at that report and it appears it is just taking the date entered and using the strtomember function. In my query, it looks like it would be the equivalent of the line with the hard coded date with:
StrToMember("[Date].[Year Week Date].[Week].&[" + Format(DATEADD("d", -7, "2008-12-21"), "s") + "]")
This works fine. However, what I really want is to eliminate the need to hard code anything. I tried using the Now() function instead of the hard coded date. I wasn't able to get it to work, but even if I did it would still mean that I'd need to change the number of days to subtract to get back to the Sunday of the previous week. It seems like there should be an MDX function that would make this work. If not, then perhaps there is some way to modify the StrToMember line to derive the previous Sunday's date in the proper format.
