Analysis :: MDX Tail Function And Calculations
Aug 3, 2010
I am looking a way to use a tail funcion to achieve something like this
If you see the picture i want obtain in one row the total amount of the month over a selected range. If I select months between 1 and 12, i want the values only for the month 12, if a select months between 1 and 10 I want only de value for October and so on.
I tried this simple mdx query:
Select
Tail([Id Fecha Orden Pago].[Mes].allmembers,1) on
Rows
,
{[Measures].[Total Gastos Orden Pago]} on
Columns
From
[CUB_DGM_TestEnamiDW] WHERE
[DIM Programa Fomento].[Nombre Programa Fomento].&[RECONOCIMIENTO DE RESERVAS]

how can use this mdx script in the calculation part of a cube, will i simply dump it in the script form by starting with the 'create member current cube.
[measures].[test]'
select
[measures].[abc] on 0,
[xyz].[xyz].(&0):[xyz].[xyz].(&60) on 1
from
(
select
(tail([month].[month].[month].members,6))on 0
from
[cube])

I have built an analysis cube and I am wondering how I can now somehow add in some kind of forecastinbg to it?
I have a time dimension in years, quarts, months, days.
Is there a way I can show forecasting calculations for future dates?

I am currently creating calculations for weekly and fortnightly ranges by day.
Is it better to use LastPeriods or Tail? For example, the last 14 days could be:
LastPeriods(14,
StrToMember
(
"[Date].[Year Week Day].[Date].&[" + FORMAT(Now(),"yyyy-MM-ddT00:00:00")
+"]"
)
))
Tail(
Filter(
{[Date].[Year Week Day].[Day]},
([Date].[Year Week Day].CURRENTMEMBER, [Measures].[Test Measure]) > 0
), 14
)
What is the advantages or disadvantages?

I am trying to compute average of Sales amount for 10 days and I am having an issue when using LAG function. Since weekends fall in between working days my LAG (10) function is also including weekends and hence I am not able to get the correct average.
For ex: D1 - 10 , D2 - 20, D3 - 30, D4 - 50, D5 - 10, D6 - W, D7 - W, D8-10, D9 - 20, D10 -30, D11 - 10, D12 - 40, D13 - W, D14 - W
I am using a sample script
SUM([Time].[Hierarchy].CurrentMEMBER : Time.[Hierarchy].Currentmember.Lag(9), [Measures].[Sales Amount])/10
When I use this and When my current member is D12 Then I am getting the value as 200/10 = 20 (from D12 to D3).
However ideally it should be 230/10 =23 (from D12 to D1) and lag should exclude D6 and D7 as it is a weekend.
I also have a working day flag in my time dimensions which says 0 for non working days and 1 for working days.

Any working example of what a ragged hierarchy should look like for the unary and custom rollup calcs to work?
I have a parent-child hierarchy that works as expected but can't manage to get the same with a flattened ragged hierarchy. Parents disappear if any of the children aren't in the fact table (even though the children are set to '~' and the parent has its own custom rollup calc).
Do I need to replicate the unary and measure formula all the way to the end in the same way i do the member name/value (so i can set ignore if same as parent)? Setting unary to null seems to work when the key doesnt exist in the fact table but the default behaviour for null is '+' so i end up getting wrong results if the key does exist!
Repro:
In words
I have an EAV style fact table. The measure name is defined in a 'dim measure' table. Some measures exist in the fact, some are manufactured using Unary ops or custom rollup formulas.
Here's a diagram of the hierarchy
I want to recreate the functionality as a flattened hierarchy (the number of levels is fixed), but can't seem to do it... Here's what I've gotten for the same hierarchy created using the two different approaches
Below are queries to recreate the tables from adventureworksdw2014. The parent child hierarchy is set up the standard way... measureparentkey is parent. set name, unary and formula as expected. Set NonLeafDataHidden for the parent attribute. I've tried various combinations for the ragged hierarchy but none work 100% of the time. I want to have a user defined hierarchy for the performance benefits.
--Fact view
CREATE View dbo.FactSales
AS
select fis.ProductKey
, fis.OrderDateKey
, 1 AS MeasureKey -- salesAmount
, fis.SalesAmount AS MeasureValue

I have a small doubt.
full backup F1 6 am
t-log backup T1 7 am.
t-log backup T2 8 am.
suppose if the system crashes at 8.30 am
the restore order is F1 T1 T2.
through this we can restore up to 8 am . then what abt 30 min data.
how can we eliminate that data loss.
generally people say we have to use tail log backup.
if we are not able to acess to sql server how can we take tail log backup.

I am trying to work with a sample database to better understand disaster recovery. I have setup a scenario with a full backup, several differential backups and several transaction log backups.
In order to simulate a crash, I renamed one of the '.ndf' files and restarted the sql server service. Ideally this would put the database in 'offline' or 'suspect' mode. I should then be able to go in via Mgmt Studio and perform a final backup log to get all the records at the tail of the log.
However, when i am unable to access the database via SSMS - I get the following error:
Msg 945, Level 14, State 2, Line 1
Database 'xxx' canot be opened due to inaccessible files or insufficient memory or disk space. See the SQL Server errorlog for details.

Hi!
i have a question regarding tail log backup.
I have set up logshipping between primary and secondary servers. Now when i want to fail-over to secondary, I am planning to take the tail log backup on primary
backup log primarydb
to disk=N'..',
with norecovery
and then I will restore this tail log backup to secondary
restore log secondarydb
from disk=N'',
with recovery
Will there be any issue with this approach?
Will I be able to recovery the primarydb if i want to, in future? Taking tail log backup doesnt cause any issues? Or do i need to take the full backup of primary before I take tail log backup..in case if I can not recover the primary db after taking the log backup?
How big the tail log backup can be? Will it be of similar size of other normal transactional log backups.?
Any help would be appreciated.
Thanks

My requirement is to count the customer order number for premium order type orders which has some order quantity.I am using below MDX
count
(
Filter
(([Customer Order].[Dim Customer Orderkey].[Dim Customer Orderkey].members,
[Outbound Order Attributes].[Order Type].&[P]),[Measures].[Ordered, pcs]>0 ) ,
)
The result is accurate but the query execution time is 3-4 minutes for 10 fact records, when i use multiple dimension. it is showing me 0 valus for this measure for all the members for the dimesion attribute which doen't have any customer order. example it shows all the member of date dimension. is there any way to reduce the rows. i think this is the reason to take more execution time.when i use EXCCLUDEEMPTY the result is NULL
count

Filter
(([Customer Order].[Dim Customer Orderkey].[Dim Customer Orderkey].members,
[Outbound Order Attributes].[Order Type].&[C]),[Measures].[Shipped, pcs]>0 ) ,

I’m trying to build a calculated member (see below script) using “Except” function but I get an error result:
#Error The function expects a string or numeric expression for the argument. A tuple set expression was used.
My idea is to take a measure and exclude 2 members from the dimension.
I tried using “Aggregate” but got the error:
#Error Query (3, 1) Aggregate functions cannot be used on calculated members in the Measures dimension.
Please note that my measure is ACD that is already calculated average in olap and I can’t use AVG function instead of Aggregate. What can I do?

There's a change in SP2 that I'm very happy about, but it took me by surprise since I haven't seen it documented or discussed:
http://www.artisconsulting.com/Blogs/tabid/94/EntryID/1/Default.aspx
Can somebody on the SSRS product team double check me that I've written that up right? That seems like a pretty important change and I can't see it mentioned in BOL anywhere.

I'm working with the statistical functions Stdev and Median with calculated members. The only way I can get the "correct" answer is if I have a dimension at the same granularity as the Fact table (Actually it's a degenerate dimension of the FACT table itself). Otherwise it seems that the measure I'm using with Stdev returns results that are so wildly high, I think it must be acting on the SUM of the measure; because the measure itself is a Summed one. When I try to use the coordinates in the Stdev function, it seems like it is using the wrong set of data points :
stdev( ( [Date].[Date].[Date].members, [Parameter].[Parameter].[Parameter].members ), [Measures].[Value]) returns answers in the thousands when it should be more like 2.5
When used with a query, there would only be a single date member and a specific parameter member. The total number of fact records is between 200 and 500 with values that range between 0 and 150. This is the version that gives me answers that resemble the total sum of the [Measures].[Value].
If I add the dimension that is essentially a row number from the fact table, it gives the right answer (slowly, but that will be a different post ....
stdev( ( [Date].[Date].[Date].members, [Parameter].[Parameter].[Parameter].members, [FACTTable].[FACTTable].[KeyField].members ), [Measures].[Value])

I am having trouble limiting a sum function to only evaluate the data in the slicer. I need a sum of data calculated per employee and when there is a slicer of one employee my measure still evaluates all employee. For example:
WITH
MEMBER [Measures].[TotalEmpHours] AS
SUM([Employee].[Employee].members, [Measures].[Actual Ovt Hours])
select
{
[Measures].[TotalEmpHours],
[Code] ....
The above reports the overtime for one employee in [Measures].[Actual Ovt Hours], I expected [Measures].
[TotalEmpHours] to be the same as there is only one employee in the slicer select. The real measure is the minimum of two values for each employee.
This is a simplified example but I think it should work.Is there another construct to iterate the employee set? I have no control over the query as it is from a pivot grid. If the filter (employee) is leftmost in the row area, then it works because the employee ends up in the row part of the query.

SELECT
non empty [Measures].[Cumm Account Count] on 0,
non empty [TRANSACTIONS].[Days].&[3]:[TRANSACTIONS].[Days].&[3].lead(60) on 1 from [cube];
and for subsequent months by using the dates that the following month starts. How can I achieve the above result without having to use the day numbers, I tried to use the tail function (to get the months and star date) but it wont work because the range function accepts members only...

Hi, all here,
I am just wondering about the Discretization function available on analysis service server (which can not actually discretize data into user-defined expressions) . Isnt it redundant ? I mean since users can discretize their data more meaningfully based on their own expressions in database engine of SQL Server 2005.
Thanks a lot.

I am relatively new to SQL-Server. I was working in a company that used SS2005. Now I am with a company and client where SS2K is my only option. I know SS2005 had Analysis Services which allowed building hypercubes but I never got the chance to learn about it or use it. I am not that familiar with what SS2K has.
I have no access to any OLAP tools. I have MS-Access and MS-Excel. My SQL-Server database has to crunch a table with thousands of rows.
Having worked with MS-Access and MS-Excel for a long time, I know how powerful creating a pivot table is. I heard that SQL2005 had a T-SQL PIVOT function but never had the opportunity to use it.
Know I have the need to do this in SQL2000.
I have a lot of data so the method shown in BOL for cross-tab won't help me. The client changes the "column" and "header" categories on a regular basis, so I need something that will allow me to NOT hard code them but choose them dynamically like one would do in a hypercube.
I have more than 5 categories for "row headers". I have currency for the data to aggregate. I have "pay periods" (26 of them) for my "column" headers, but not all 26 will be present until Dec 31, so that part has to be dynamic.
Question:
Is there any feature in the standard S2K that allows one to create anything like a pivot table without massive coding (T-SQL function or technique or something like a hypercube ability)?
Can you point me to something on the web that would explain how to get started?
Many thanks ahead of time from a newbie!

I have, a SSAS 2012 tabular instance with SP2, there is a database on the instance with a read role with everyone assigned permissions. When configuring the Power BI analysis services connector, at the point where you enter Friendly Name, Description and Friendly error message, when you click next I receive the error "The remote server returned an error (403)." I've tested connecting to the database from Excel on a desktop and connect fine.I don't use a "onmicrosoft" account so don't have that problem to deal with.
We use Power BI Pro with our Office 365. As far as I can tell that part is working ok as I pass that stage of the configuration with a message saying connected to Power BI.The connector is installed on the same server as tabular services, its a Win2012 Standard server. The tabular instance is running a domain account that is the admin account for the instance (this is a dev environment) that account is what I've used in the connector configuration. It's also a local admin account. There is no gateway installed on the server.

I have a cube that we are processing nightly via an Analysis Service Processing Task in SSIS. In order to increase the performance of the processing time, we elected to use a lot of rigid dimension attributes, and do a full process of everything in the SSIS task. The issue that I am having is that after that task completes, I need to go into Visual Studio to deploy the cube becuase we are unable to browse or use the cube. This issue seemed to start once we changed the SSIS Analysis Service Processing Task to do a full process on the dimensions, rather than an incremental.
I would expect that once development is done, and it is processed and deployed, that is it. My thinking is that the SSIS task should just update the already deployed cube,

I am using
SSAS: version 2008
Excel: version 2013
I am connecting to SSAS cube from Excel and I have date dimension with 4 fields (I have others but I don't use it for this case). I created 4 fields in order to test all possible scenarios that I could think of:
DateKey:
- Type: System.Integer
- Value: yyyyMMdd
Date:
- Type: System.DateTime
DateStr0:
- Type: System.String
- Value: dd/MM/yyyy (note: I am not using US culture)
- Example: 01/11/2015
DateStr1:
- Type: System.String
- Value: %d/%M/yyyy (note: I am not using US culture)
- Example: 1/11/2015
Filtering on date is working fine:
Initially, in excel, filtering on date was not working. But after changing dimensional type to time, and setting DataType to Date, as mentioned in [URL] filter is working fine as you can see in the picture.Grouping on date is not working:
I have hierarchy in my Date dimension and I can group based on hierarchy, no problem. But user is used to pre-build grouping function of excel, and he wants to use that. Pre-build functions of Excel, Group and ungroup seems to be available as you can see in following picture:
But when user clicks 'Group', excel groups it as if it is a string, and that is the problem. User wants to group using pre-build grouping function available in Pivot table. I also find out that Power Pivot Table does not support this excel grouping functionality. And if I understood well, this pre-build grouping functionality of excel, needs to do calculation at run time, and that is not viable solution if you have millions of rows. So Power pivot table does not support pre-build grouping functionality of excel and hence we need to use dimension hierarchy to do the grouping. But I am not using Power Pivot table, I am using simple Pivot Table. So I expect grouping functionality to be working fine. Then I tried to do simple test. I created a simple data source in excel itself. And use it as source of my Pivot table. Then grouping is working fine. The only difference that I can see is (When double click the Measure value in Excel),For date values of my simple test, excel consider them as 'Date'.
For date values of my data coming from cube, excel consider them as 'General'
2.1. But value here is same as it was in simple test.
2.2. 'Date Filter' works just fine.
2.3. If I just select this cell and unselect it, then excel change type to 'Date' though for that cell.
2.4. I have created 4 different types of fields in my date dimension thinking that values of attribute of my dimension might be the problem, but excel consider 'General' for all of them.
2.5 This value (that can be seen when double clicking on measure) comes from 'Name Column' of the attribute. And the DataType defined is WChar. And I thought that might be the reason of issue. And I changed it to 'Date'. But SSAS does not allow it to change to 'Date' giving error : The 'Date' data type is not allowed for the 'NameColumn' property; 'WChar' should be used.
So, I don't know, what is the puzzle piece that I am missing.
1. Date filter works, group does not work
2. Excel consider it as 'General' string.
3. SSAS does not allow to change 'NameColumn' to Date.
