Dynamic Security is not working when connection performs via https

$

0

Hi,

I've realized a HTTPS connection like in the link below:

https://msdn.microsoft.com/en-us/library/gg492140(v=sql.110).aspx

The problem is when I tried to implement dynamic security based on the DimUser dimension (there is an attribute contains Login) I faced an interesting issue. I'm using well-known MDX script over the Login attribute:

{StrToMember("[Users].[Login].&[" + UserName() + "]")}

When I connect to the cube from the local intranet(not the https) it works fine. But when I connect over the internet ( via https ) it's not working. I've checked the user in the SQL Profiler from which the MDX query is executed and it defines the same in both ways.

I have a ROLAP storage mode and use "Real Time Olap=True;" option inside the connection string. I've also tried a MOLAP mode but it behaves the same. 

Could anyone tell me the reason it mays come, please. I'm trying to resolve this problem within 3 days and can't move forward((


Seeing my Staging table when Processing Partition SSAS 2005

$

 When I Process my Partition and drill down to the SQL query I see it reference my Staging table and not my Fact table. It seems to be processing
the true Fact table I have, but not sure why I'm seeing this other table. Where can I look to the why I'm seeing that Staging table. I think it maybe causing the rebuild to Process longer than needed and maybe effecting Pivot Table query response.

 Doesn't make any sense where it's picking up that reference.

 Thanks.

Full Cube processing occasionally fails

Hi,

I am facing an issue where the processing of a cube sometimes fails with the following error message:

Error in OLAP storage engine: error processing the A NET EXPOSURE-Partition of the A NET EXPOSURE-Measure group for the ExposureInsightsCube-Cube of the REDS_ANALYSISSERVICES-Database.
Server: The Process has been cancelled.
Error in OLAP storage engine: error processing the indices for the A VULNERABILITY EXPOSURE-Partition of the A VULNERABILITY EXPOSURE-Measuregroup of the ExposureInsightsCube-Cube of the REDS_ANALYSISSERVICES-Database

Processing the cube with the same data afterwards just works fine. I currently struggle on how to get more insight on why the cube fails the processing, but also on what this error means.

We have a single table Tabular cube and it has worked fine for a long time. Recently we added additional fields and also the record count increased. With the increased data, if i process the cube in Visual studio and save it and reopen it, i am unable to open the model. It gives out the below error message

Error Message: The Server has sent an unrecognizable response

If i try again after clicking OK, i get a new error message.

Error Message: Model already open

Sync Tabular table/table partition to the model in another server along with data to reduce the Sync time

 Hi,

I am experiencing the server analysis server unavailability while Restoring or Syncing the Tabular Model(50+ GB) from anotherserver.

I know that this is happening due to tabular architecture, but this made the model to unavailable for some time.

 I did went through many blogs, but I could not find the way to avoid this unavailability.

Currently I need the way to Copy/Sync the tabular table(or tabular table partition) only to another server instead of Syncingwhole model. So that we can reduce the time to Sync and we can make sure analysis server unavailability.

Please Let me know is there a script to handle the above scenario, it will be helpful.

Thanks in advance.

Sql analysis services role full administrator permissions restarted

Dear SQLAS users,

I have a strange problem with Analysis services. When I created new roles in a database in a analysis services instance, I gave the users inside this roles full administrator permission. But when I checked it after a day or two the full administrator permission was unchecked. I redone the procedure and it has unchecked it again.

Why is this happening?

Sincerely,

The Customer want to click the dimension and see the data  not the attribute name

i.e DimGender

Tabular Model Offline during Sync

Hi Guys,

We are facing a issue with production system where the Query Server is inaccessible during the Sync. Tabular model is processed on a different server and then a sql job is used to run the Sync command.

Can you please tell me if this is normal or something is wrong. What is the default behavior? Memory/CPU usage are ruled out.

Any pointers what to look for ?

Thanks.

Error on Tabular data source using Oracle

Hello,

we need to load in the Tabular Mode Analisys service some data from Oracle 11 database.

We have installed Visual Studio 2015 update 3 on a Windows 7 32 bit machine

We have installed the Oracle Client on the machine.
ODBC work fine
Excel can connect to Oracle (PowerPivot)

Visual Studio 2015 add a Oracle DataSource. When test the connection after the configuration is OK, I see the list of ORACLE database table but when try to import the data the system ask me for User name and password and we are unable to logon. Always password failed.

On the SQL Server I have the oracle client and I can configure Oracle as a Linked server and all work on the server side.

Some idea on how I can solve or indagate the problem?

SSAS Multidimensional hardware

$

Greetings all

I am working with a client to install their first SSAS multidimensional cubes.  While there is plenty of information on hardware sizing for tabular models I can find very little multidimensional models.  Right now we're working with a 10+ TB DataMart (not all of that is going in the cube) and I am estimating a cube size of about 500 GB for starters with much more to follow.  For example, the next thing I'm working on will involve a fact table that we are expecting to grow by 500K records/day on average. 

If anyone can point me to articles or other information that my Google/Bing skills failed to uncover or has any suggestions about sizing, it would be much appreciated.

Thanks in advance

Create hierarchy classifed according the date

hello,

   For one of my client, i need to create a hierarchy in dimension that display the attribut dépends on the dates, for example :

Hierarchy Society :

Society Date of creation     Date of   modification   Date of end
A 01/01/2012 01/03/2013   null
B 01/01/2012         null    null
C 01/01/2013        null   null

D                    01/01/2012             null                             01/01/2013

i need to have in my hierarchy :

 2012 -> Society A,B and D

2013 -> Society A,B and C

Someone can help pls?.

need help with calculated member

$

I have a calculated member that doesn't add up to the total line in the pivot table.

I will try to explain with the sample pivot table below

CREATE MEMBER CURRENTCUBE.[Measures].[total client cost]
 AS
  sum(Descendants([Version].[Version Hierarchy].CurrentMember,
                    [Version].[Version Hierarchy].[Month]),
        [Measures].[Total Client items]  * [Measures].[Cost Per Item]),
FORMAT_STRING = "$#,##0;($#,##0)";   

The issue is if you add up column I for total client cost (rows 22 - 28)

$128,476
$0
$565,182
$1,097,124
$2,048,151
$6,083,148
$0

You get $9,922,080 but the total total client cost is showing $8,959,816 (I31)

This is because the user requested that at the quarter level we add the previous 3 months totals

so for qtr1 we have $2,597,824 which is the sum of Jan $840,522 (B31), Feb $891,967 (C31) and Mar $865,335 (D31)

so at the year level or budget total it adds the previous 4 quarters (qtr1, qtr2, qtr3, qtr4) for the corresponding row which is correct.

Even at the total level for the measure "Total client cost" for Jan we have $840,522 (B31) it doesn't add up to the column

total client cost
Region 1$6,793
Region 2$0
Region 3$53,232
Region 4$92,189
Region 5$228,687
Region 6$533,428
Other$0

                                                           = $914,329

In this case above is taking 2085 * 403.1281 (pivot displays 403.13 as it rounds)= $840,522 but I would like to have it do the sum of total client cost to get $914,329.

The totals lines on the right do sum the parts to the left and get correct values.

for example total client cost

Region 1 total = $128,476 which adds qtr1 $26,412 (E22), qtr2 $30,617 (F22), qtr3 $35,617 (G22), qtr4 $35,829 (H22)

I would like to change the way the pivot is adding up the columns not the rows as the row totals are ok and correct for us. Is the column totals, so column B-I for row 31.

Is there an MDX script that can accomplish this? But the dimensions could be others so I don't want to hard code the regions. I want to treat the totals lines different by adding the parts above it.

Tabular 2016 DirectQuery Mode - "Sort By Column" Behavior

$
0
0

I'm creating a proof-of-concept using tabular 2016, in DirectQuery mode.  In the process of building out a sample model, I keep running into the following error message when browsing the model in Excel: 

"DirectQuery error: There are duplicate values for [sort order column name]. Only one-to-one relationship is supported between members of [display column name] and '' attributes."

The data in the dimension causing the error is denormalized and has a standard category / sub-category setup.  For example, the data looks something like this:

Section....SectionSort....SubSection.....SubsectionSort
    1..............1....................1......................1
    1..............1....................2......................2
    2..............2....................1......................1
    2..............2....................2......................2

I thought it was possibly complaining because "SubsectionSort" is repeated within each Section, so I created a unique sort value at the subsection level, but this didn't solve the problem. Am I modeling this incorrectly?  Or is this some kind of limitation in DirectQuery mode? I can't find a whole lot of documentation on this. Thanks for any help!

Which has better concurrent user performance, Tabular or Multidimensional?

In the continuing saga of scaling out SSAS, the team is now wondering if Multidimensional can handle more concurrent users than Tabular.  Also, how does either form on SSAS do with multiple servers?  Does it scale horizontally?  If we add more servers, can SSAS distribute the workload or the users?

Value of using SSAS over Excel Pivot Tables

$

I’ve moved into an analysis team that defines columns for reporting in SSMS, and reduces the number of records by pre-aggregating (grouping by columns of interest). Then they use Excel pivot tables to do any further slicing and dicing etc. It all seems logical but would SSAS work better?

DAX Help Navigating Hierarchy

$

I have measure in an SSAS tabular model with the following calculation:

COUNTROWS (
    FILTER (
        SUMMARIZE (
            'AggSurveyAnswer',
            AggSurveyAnswer[CCNDisplayName],
            "Population_PctTopBox",CALCULATE ( [% Topbox Agg] )
        ),
        CALCULATE ( [% Topbox] ) >= [Population_PctTopBox]
    )
)

The primary interaction with the model is through Excel.  I also have a dimension table called 'Survey' that contains a natural hierarchy of [Survey Type] --> [Survey Subtype].  The 'AggSurveyAnswer' in the calculation above has a relationship with the 'Survey' table.  I need to modify the results of my Population_PctTopBoxmeasure so that if the user filters on [Survey Subtype], it gets filtered on the corresponding [Survey Type] value.  

In other words, the calculation should ignore the [Survey Subtype] filter (if it exists), but instead apply a filter on the set of [Survey Types] that correspond to the [Survey Subtypes] that were selected.  If the user only selected a [Survey Type] filter, then that should be used.  I think I need to use the ISFILTERED function as outlinedhere, but I cannot get it to work.  Any guidance is appreciated!

Error occurred retrieving child nodes :SSAS ROLAP

$

Hi All

 

I am facing a strange issue with analysis server 2012. I have cube based on ROLAP storage mode. I have followed this storage mode due to our requirement. Everything works fine at the initial stage with fewer data. Now the cube is in testing phase where the testing group is testing the cube with much more data. It gives some storage like “Error occurred retrieving child nodes: Error in the OLAP storage engine: The process operation ended because the number of error encountered during processing reached the defined limit of allowable errors for the operation”. 

 

The cube works fine if I change the storage mode from ROLAP to MOLAP.

 

Could you please suggest what could be the problem?

 


 

Thanks a lot.
