Hello,

We have created 'alias' names for SSAS Tabular servers and trying to use this in SSRS connection string. Actual SSAS tabular server name works but 'alias' name is throwing the below error when deployed in SSRS server.

/**

An error has occurred during report processing. (rsProcessingAborted)
- The execution failed for the shared data set 'DataSet1'. (rsDataSetExecutionError)
  - Cannot create a connection to data source ' Data source for shared dataset'. (rsErrorOpeningConnection)
    - The connection either timed out or was lost.
      - Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
        An existing connection was forcibly closed by the remote host

**/

Tried pinging actual / alias ssas server from ssrs server - Works fine pointing to the same IP address.

Please advise for any insight on this issue.

Hi,

Good day!

Just wanted to reach out and ask help/advise regarding our issue with using Excel connecting to SSAS.

We have recently upgraded from 2008R2 to 2017 SSAS (multi dimensional)

However, during testing we found that some queries are running noticeably slower than the old version - particularly if we are doing pivot tables connecting to the new cube. We have generated the MDX and tested from old version that it runs for around 12 sec, but the same MDX (generated from Excel) runs for around 3-5 mins on the upgraded SSAS.

I can send the config file (ini) of the old and new server as well as the MDX generated if needed.

Kindly advise.

Thanks,

Jaycee Robles

Hello I'm not totally sure if this is the best place for this question but figured I'd give it a shot,

I've got a query that has multiple operations for each particular production order and it is working as intended. However, I'd like to be able to trim this down to improve performance (I'm only using the query for the final operation for each production). I can do this via using the max when creating my query in dynamics AOT. The issue is whenever there is a group by included in these query setups, I get an error.

Seen here:

I'm just curious if anyone has any thoughts an a solution or alternative to this.

Hi Everyone,

I have cubes developed in Multidimensional Model, the cube sizes range between 20 and 40GB. We want to migrate these cubes to tabular models developing from the scratch. I am concerned about the performance of the cubes, we develop a demo cube with a DAX function and less than 300k records, but the response is very slow.

Does anyone know if it is a good idea to do this migration or is better to stay with multidimensional cubes.

Thanks for your answer.

Hi all,

I built a SSAS Tabular Cube which is Direct Query against SQL Server. Let's I have a Table with 10 columns when I first built the cube and later on I have added one more column to the table which makes up to 11 Columns in that table. I want to see that column to be added into the cube dynamically so that end user will browse the cube for the column in power bi.

I know we can manually update the metadata in visual studio and redeploy. But is there is any way that i can make the flow of metadata dynamic ?

≪ Previous: How to make Metadata refresh Dynamic in SSAS Tabular Direct Query against SQL Server

Hi. are there alternatives (even with other vendors) out there to the tabular model? I don't like the tabular model training and instructional reading alternatives. the courses don't seem to set a proper foundation.

Dax seems inconsistent and overly complicated, perhaps immature. our app is survey based which means there are questions, answers, forms, studies, people (those being evaluated and those doing the evaluation) etc .

our app has facts, dims and comments so I dont like multi dimensional ssas in this case.

column stores don't seem as fast as advertised (I think they are 4 times not 10 x faster than conventional tables). and besides they cant contain large comments either.

I've seen xml "ish" based data stores that I believe are free ware and amazingly fast. I'm going to ask a peer how that technology worked for him and i'll post the name(s) here.

hierarchies (eg org etc) play a role in our data. changing dims, ie your boss was joe yesterday but jane today also play an increasingly important role in our data. there are 100 million data points. 90 dims. 7% of the data points are long char fields.

We have Tabular model with say Platform Dimension, ( members: Android, iOS, Windows, Mac etc).

Question: We want to hide few Platforms (say "Android" and "iOS") from dimension member list to the Users (client tool: Excel).

*Rows for Andriod and iOS will be used for some other Measure calculation so cant really filter out of query.

Hi,

I recently enabled TLS1.2 exclusively(only 1.2 enabled with all others like TLS1 and SSL disabled) on my SQL server. I installed all necessary patches mentioned in:

https://support.microsoft.com/en-us/help/3135244/tls-1-2-support-for-microsoft-sql-server

My program is able to connect to the sql server and everything works fine except the operations on the analysis service using AMO.

Some extra info:
Windows server 2012 R2
SQL service 2014 sp2
.Net Framework 4.7

The sample test code is shown below, nothing special but going to process the dimensions:

using Microsoft.AnalysisServices;

try
{
using (var server = new Server())
{
server.Connect("localhost");
server.CancelCommand();
using (var database = server.Databases["mydb"])
{
foreach (Dimension dim in database.Dimensions)
{
dim.Process(ProcessType.ProcessFull);
}

}
Console.ReadLine();
}
}
catch (Exception ex)
{
Console.WriteLine(ex);
}

A exception thrown as below when calling the dim.Process(ProcessType.ProcessFull). As shown, it is able to connect to the server and list the databases and dimension but failed to process the dimensions.
It was a connection issue based on the information, I am pretty sure it is caused by the upgrade to TLS1.2, because the same code worked before.

Microsoft.AnalysisServices.OperationException: Internal error: The operation terminated unsuccessfully.

How to create a new calculated column in Excel - Getting data from SSAS model into an excel tabular form

October 10, 2019, 10:43 am

≫ Next: How to use OR filters for getting data from an SSAS model into an excel tabular form

≪ Previous: OLE DB error when processing dimensions in Analysis services using AMO with only TLS1.2 enabled on the server

We are loading data from an SSAS model into an excel tabular form and we are trying to put information in a second column depending on the first one, In this case we have 2 fields coming from the SSAS: Amendment Amount and Record Date, we are trying to change the column Record Date depending on the information coming from Amendment date.

It means, if Amendment amount comes empty from SSAS we have to put blank spaces in the column Record Date. In contrast, if some data comes in the amendment amount field we need to put the information coming from Record Date field It could be explained as a formula as well as follow:

IF(PO[Amendment Amount] >0,PO[Record Date] )

Question about amendment date:

What is the best way for doing this kind of calculations? Notice that data is coming from SSAS into Excel tabular form
Is there some conditional formatting available to apply in this case?
Example: Is displaying information in Record Date column when we don't have amendment amount, it is wrong:

po_number | Record_date | Amendment_amount

A1 | 2019-05-03 |
A2 | 2019-05-25 | 4350
A3 | 2019-04-30 |
a4 | 2019-04 08 | 2100
We are looking for something like this: (if we have Total amendment Amount we show up Record date, else we show up blank spaces)

results expected:

po_number | Record_date | Amendment_amount

A1 | |
A2 | 2019-05-25 | 4350
A3 | |
a4 | 2019-04 08 | 2100
Note : We do not want to do changes to the model (visual studio), we want to do changes on Excel, specifically on each Excel report as needed.

One more thing : Amendment_Amount is a measure field coming from the model(visual studio) I tried to use a MDX calculated measure (OLAP tools) as follow, but it doesn't worked:

IIF( ( Not(IsEmpty([Measures].[Amendment Amount])) AND [Measures].[Amendment Amount] >0 ), [PO].[Record Date], 1 )

Some idea to solve it please?

Hello All,

In Cube for measure group, the base table is actually appears at 3 different places(let me know if more places are there)

1. in DSV, under table section.

2. in DimensionsUsage Tab, to set the relationship b/w measure group and dimension

3. Partitions.

Can you please let me know the impact & how SSAS works when we change table name any of these but not other places?

For example: If we change in DSV by replacing table with other table, but do not change in partitions or vice versa.

We have a single server enterprise license which allows us to run a cluster of 2.

I cant seem to find any info, if I am allowed to process the cube on the dormant server.

Feels like it should be fine as nobody is connecting to it, but if anybody has any experience with this or can point me to some reference material, it would be much appreciated.
