We are using SSAS 2016 Enterprise

We are building a mega cube with multiple companies data and we want to partition by Company.
We also will want to schedule separate ETL schedules for each company.


Question is in the event there is failure from a partition perspective will that take down the entire cube? In the event the data from one company goes wonky?

hi,

is it possible to connection Oracle OLAP , Oracle application server, Oracle BI answer and BI server to MS SQL ?

we are thinking about what if we just migrate Oracle DB to MS SQL DB and left the rest untouched.

Hi, I am connecting to SSAS data cube (tabular model) from Excel. This is company's operational data. I am wondering if there are any templates I can reuse to visualize data. What is the best place to start? Any books/video suggestions, other resources?

Thank you in advance.

When communicating with SSAS msmdpump via SOAP requests Analysis services returns with Content-Types that are compressed and in binary XML (Content_type: xs+xpress).

We would like to include an extra layer of abstraction between the client and Analysis services and would like to know if there is a way to have Analysis services send back plain XML or how to read the xs+xpress content-types.

Is there a way in SSAS 2016 and the latest version of Excel 2016 to add a value to the Description property of a Dimension Attribute and have that render as a tooltip when hovering over it in Excel?

I have an excel 2016 pivot table that is using a data connection to an ssas 2012 Olap cube

When I try to add a timeline slicer I get the dreaded

We can't create a timeline for this report because it doesn't have a field formatted as a date

I do have an order date attribute that is defined as a date field on the dimCalendar table

I have done some research and found some possible causes

one possible issue mentioned is that the field may have blank or invalid dates.
(I double checked this is not the case in my data)

The other was that the field needed to have the

ValueColumn of the date key to use an actual date field from the underlying SQL table.  The KeyColumn is an integer and the NameColumn is WChar.  and to set the ValueColumn to use type Date

I validated this was true as well

Anyone have some other thoughts

The attribute key cannot be found when processing: Table: 'dbo_FACT_PROD_QTY', Column: 'CONTRACT_RATE_KEY', Value: '0'. The attribute is 'CONTRACT_RATE_KEY'.
The attribute key was converted to an unknown member because the attribute key was not found. Attribute CONTRACT_RATE_KEY of Dimension: ContractRateLevel f

- I can process the dimension (ContractRateLevel), that the Fact table is pointing to with no problem.
- The dbo_Fact_Prod_Qty table does have Nulls in column Contract_Rate_Key.
- There are no Null values in the Dimension table: ContractRateLevel.

Can someone help, as I don't have this issue with my test cube, and the Fact table as NULL values for the same column.

I want Excel to prompt me each and every time for credentials each time i try to connect to the cubes. I don't want them saved ever.

Where does that setting live?

the two servers involved are sql 2014 and sql 2016
Our billing system is an OLTP database and it is very hard to report off of.   I have been reading on OLAP and ssas.  Is there a good manual or starting place for a rookie to try to overcome the reporting issues.
any ideas on should i start with trying to use ssas or creating an olap database from the online transactional database.

All,

I'm getting the following error when I try and process my SQL data cube:

Errors in the OLAP storage engine: A duplicate attribute key has been found when processing: Table: 'dbo_DIM_GEO', Column: 'CITY', Value: 'COLUMBUS'. The attribute is 'CITY'.

How do I correct the issue?

Power BI desktop and url connection to SSAS  cubes using the http msmdpump.dll. How to?

We have a url setup that gives a user access to our SSAS Cubes in Excel. That works fine no problem. (http://olap.mycubes.com)

But now we have a new user that needs to do the same thing in Power BI.

When I enter the URL in the prompt for server it gives me an "unsupported data format" error.

How do go about doing this for Power BI?

Hi,
I have invoice Header and Invoice Line Details fact Tables.
After creating Cube Invoice Header is working fine.
But Invoice Details not working properly, for example all are showing same value.(repeating)
In the invoice Header have customerID, But Invoice Details Don't have CustomerID.
Invoice Header Customer ID connected with DimCustomer,but invoiceline not connected with DimCustomer  Table.

Note: FactInvoiceHeader and FactInvoiceLine connected with Invoice Number
I tried to use Dimension Usage to connect but it's not working, Any idea how to connect with this

I want to create a cube that encompasses all companies. But there is security concern about a user accessing data across companies when the users access the cube via excel etc...

Having a unified cube would greatly give us granularity across time. (some companies sell assets to other companies so this would make sense when slicing the data to get accurate numbers.

Would a feasible solution be to add a company dimension and somehow hide it..or implement some kind of partitioning?

Any general suggestions would be helpful.

I am fairly new to PowerPivot in Excel and I was wondering about how you could use two tables of unrelated data in a pivot table.  I understand about how you can relate two tables like Customer and CustomerOrder that share a common key, but what about something like this:

Claims Table:
Claim Number
Claim Type
Year of Loss
State
County
Zip Code

Population Table:
Population Count
Year of Census
State
County
Zip Code

There isn't a true key that connects these Tables but they have many fields in common.  So if I was to list Florida Hurricane claims by loss year in a Pivot table is there any way to also list the Population for Florida for the same years?  Is there a solution that would automatically switch if I changed from State = Florida to County = DUVAL?  Could this be done with a DAX expression?

For example I have the below MDX query where it gives me all the data i want. however i would like to column slice all the 20K DWT's in one column and all the 25K DWT's in another column. Could I replace all the information in the FROM columns section with something like  [Voyage].[Vessel Tag].&[LIKE %20K DWT%] , [Voyage].[Vessel Tag].&[LIKE %25K DWT%] ON COLUMNS?

SELECT NON EMPTY Hierarchize({DrilldownLevel({[Voyage].[Vessel Tag].[All]})}) ON COLUMNS ,
       NON EMPTY Hierarchize({DrilldownLevel({[Date].[Month].[All]})}) ON ROWS  
FROM (SELECT ({[Voyage].[Vessel Tag].&[FCCSP, 20K DWT, Eco, M],
               [Voyage].[Vessel Tag].&[FCCSP, 20K DWT, Eco, H],
               [Voyage].[Vessel Tag].&[FCCSP, 20K DWT, Eco, F],
               [Voyage].[Vessel Tag].&[FCCI, 20K DWT, Eco, Ma],
               [Voyage].[Vessel Tag].&[FCCI, 20K DWT, Eco, Le],
               [Voyage].[Vessel Tag].&[FCCI, 20K DWT, Eco, Ho],
               [Voyage].[Vessel Tag].&[FCCI, 20K DWT, Eco],
                     [Voyage].[Vessel Tag].&[FCCSP, 25K DWT, Eco, Marc],
               [Voyage].[Vessel Tag].&[FCCSP, 25K DWT, Eco, Ho],
               [Voyage].[Vessel Tag].&[FCCSP, 25K DWT, Eco, Fra],
               [Voyage].[Vessel Tag].&[FCCI, 25K DWT, Eco, Ma],
               [Voyage].[Vessel Tag].&[FCCI, 25K DWT, Eco, Le],
               [Voyage].[Vessel Tag].&[FCCI, 25K DWT, Eco, Hy],
               [Voyage].[Vessel Tag].&[FCCI, 25K DWT, Eco]}) ON COLUMNS

im Using Analysis Service for SQL Server 2014. im trying to write a simple query that cuts the amount both by Month on the row level and Vessel Tag on the column level. this get me row just fine, the second i try to cut the amount by column  [Voyage].[Vessel Tag] i get the below error. Whats the correct MDX syntax to slicing it by  [Voyage].[Vessel Tag] for column?

SELECT NON EMPTY { [Measures].[TCE] } ON COLUMNS,
              NON EMPTY { ([Date].[Month].[Month].ALLMEMBERS ) }  ON ROWS
FROM ( SELECT ( { [Date].[Year].&[2017] } ) ON COLUMNS
FROM [cube]) WHERE ( [Date].[Year].&[2017] )

"The query cannot be prepared: The query must have at least one axis.
The first axis of the query should not have multiple hierarchies,
nor should it reference any dimension other than the Measures dimension..
Parameter name: mdx (MDXQueryGenerator)"

Using SQL Server 2014 and I'm trying to merge Analytic data and Relational data for a report. I'm almost there but there are parts that need to be dynamic in the MDX part.

See attached query. I need the DATASOURCE dynamic, the Initial Catalog dynamic, and the year currently hardcoded as 2017 dynamic. I try to replace them with variables and it keeps giving me errors.

I had this question after viewing Setup of SSAS Cube.

I am still having issues with creating a new data source.

Still looking for HELP, I AM DESPERATE. I have tried numerous approaches including the great help from Kevin Cross.  I am VERY STUCK, I cannot move forward in my training until I resolve this issue.  How do I create a new DSV when I keep getting the following error message:

"TITLE: Microsoft SQL Server Native Client 11.0

We have a 2-node Windows 2008 R2 active/active SQL cluster. The SQL database is 2008 R2 but the SSAS instance is 2005 and needs to be upgraded to 2008 R2. The SSAS instance runs on it's own node with it's own clustered san drive for storing cube data etc.

We don't have a test cluster, but have upgraded SSAS 2005 to 2008 on the UAT and DEV single server environments without a problem.

We were expecting to perform the upgrade on the SSAS passive node first, then failover and make that node active and upgrade the other passive node.  As a test one of our DBAs ran the upgrade wizard on the SSAS passive node (the one where SQL database is running but SSAS isn't), expecting the wizard to identify the SSAS install. But the SSAS instance doesn't appear - it only appears in the wizard as available to upgrade on the active node.

Is this normal? What is the correct procedure to proceed with this upgrade?

We considered installing a new SSAS 2008 instance to run alongside 2005, but that seemed over-complicated: it would have a different instance name, a different drive letter and would require a new cluster config. As we can use our UAT server to temporarily create cubes in production if we break SSAS on production, we have a fallback position.

Thanks!

I am a newbie to SSAS and I am having difficulty setting up the Data Source, I am unable to successfully create a connection to my database for the data source.  What am I missing?

See attached for location of data files.  

How do I determine where my localhost is located?  Note this is all on my local machine, no outside servers involved.

What is my server name, do I need to include the entire filepath?

I am using Visual Studio Data Tools for 2015.

I have been tasked with moving some SQL Server reporting cubes from Server A in Datacenter A to Server B in Datacenter B and want to make sure I'm not missing anything (this is way outside my usual ball park of operations - I'm mostly an Oracle guy).

So far I have identified:

* There is a pair data warehouse databases that need moving - Simple DB backup and Restore for initial setup should work
* There are 4 SSAS Cubes.  I believe this is a backup of each cube and restore on new server
* There are several SSIS packages that need to be exported individually and re-imported into the new server
* There are several SQL Server Agent jobs that refresh these cubes that will need to be copied to the new server

Are there any other steps I need to be aware of or pieces that might need to be moved that I haven't listed above.

Thanks

how do I join two queries, join them HORIZONTALLY, i.e. extra columns, second columns query 2 to right of first query



--query 1 OUTPUTS
SELECT a.timeStampKey, t.timeStamp,MAX(CASE WHEN a.PIE2_O_ID = 1 THEN value END) AS 'K_DESIGN_SG_A_AVERAGE_A', MAX(CASE WHEN a.PIE2_O_ID = 2 THEN value END) AS 'K_DESIGN_SG_B_AVERAGE_B'FROM   tblOutputs as a INNER JOIN       tblTimeStamp as t ON a.timeStampKey = t.timeStampKey GROUP BY a.timeStampKey, t.timeStamp
--query 2 INPUTS
SELECT a.timeStampKey, t.timeStamp,MAX(CASE WHEN a.PIE2_I_ID = 10104 THEN value END) AS Flow, MAX(CASE WHEN a.PIE2_I_ID = 10006 THEN value END) AS Head FROM   tblInputs as a INNER JOIN       tblTimeStamp as t ON a.timeStampKey = t.timeStampKey GROUP BY a.timeStampKey, t.timeStamp
