BAM external data source

We have around 400k records on which we want to build reports and in our initial approach we are planning to store the data in external tables and use external data source. For POC we created external tables and data source with around 55k records and some basic reports which used sum to group the data. For some reason this report won't load and we don't see any exceptions in the logs. In database session we can see the query it's executing and when we run the same query from sql plus, it returns data within less than 1sec. So we are unsure what the issue could be.
We are looking for some pointers on what should we look for and how we can resolve this issue. Also if there is any way to specify jdbc connection pool properties.
Thank you

BAM is not for reporting purpose. It is ONLY for dashboard purpose. BAM itself has few over heads. So the response is not only dependent on query execution.
Try creating only updating list with no conditions. Check if it is working. then go for complex reports with conditions.

Creating Sql Server 2005 External Data Source

Hey guys, I'm trying to connect to an SQL Server 2005 database directly from the BAM external Data Source.
I have the driver name and the connection string, login and password. I also have the driver, but BAM doesn't seem to have a "drivers" folder. So when I try to connect, I get:
BAM-00008: Invalid Oracle driver name
Source: "java.lang.ClasssNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver" ID: "InvalidOracleDriverName"
Has anyone done this before? Am I only allowed to connect to an Oracle Database from BAM? Thanx!

Hi,
I use BAM with SQL Server External Data Source and works fine.
In the Architect set this parameters on conection with SQL Server (EXTERNAL DATA SOURCE):
Driver: SQL Server
Connection string / URL: SERVER=<host>;DATABASE=<name_db>;
<host> = ip or name of the server
<name_db> = name of the database on the SQL Server
I use BAM 10.1.3.3.0 with SQL Server 2005

For #5, not Windows, ConfigMgr 2012 R2. Anything before ConfigMgr 2012 R2 is not supported for the 8.1 ADK.
For the permissions, what accounts are you setting this for. In general, if the share is on the same server, Everyone Full or Read on the Share and System Full or Read on the NTFS should work.
For the error message, it looks like you are trying to import an OS Image and not an OS Install Package. OS images use a WIM file and OS Install Packages use the entire set of source files from the media. For OS images, you must thus explicitly point it
to a specific WIM file.

Excel SSAS Tabular error: An error occurred during an attempt to establish a connection to the external data source

Hello there,
I have an Excel report I created which works perfectly fine on my dev environment, but fails on my test environment when I try to do a data refresh.
The key difference between both dev and test environments is that in dev, everything is installed in one server:
SharePoint 2013
SQL 2012: Database Instance, SSAS Instance, SSRS for SharePoint, SSAS POWERPIVOT instance (Powerpivot for SharePoint).
In my test and production environments, the architecture is different:
SQL DB Servers in High Availability (irrelevant for this report since it is connecting to the tabular model, just FYI)
SQL SSAS Tabular server (contains a tabular model that processes data from the SQL DBs).
2x SharePoint Application Servers (we installed both SSRS and PowerPivot for SharePoint on these servers)
2x SharePoint FrontEnd Servers (contain the SSRS and PowerPivot add-ins).
Now in dev, test and production, I can run PowerPivot reports that have been created in SharePoint without any issues. Those reports can access the SSAS Tabular model without any issues, and perform data refresh and OLAP functions (slicing, dicing, etc).
The problem is with Excel reports (i.e. .xlsx files) uploaded to SharePoint. While I can open them, I am having a hard time performing a data refresh. The error I get is:
"An error occurred during an attempt to establish a connection to the external data source [...]"
I ran SQL Profiler on my SSAS Server where the Tabular instance is and I noticed that every time I try to perform a data refresh, I get the following entries:
Every time I try to perform a data refresh, two entries under the user name ANONYMOUS LOGON.
Since things work without any issues on my single-server dev environment, I tried running SQL Server Profiler there as well to see what I get.
As you can see from the above, in the dev environment the query runs without any issues and the user name logged is in fact my username from the dev environment domain. I also have a separated user for the test domain, and another for the production domain.
Now upon some preliminary investigation I believe this has something to do with the data connection settings in Excel and the usage (or no usage) of secure store. This is what I can vouch for so far:
Library containing reports is configured as trusted in SharePoint Central Admin.
Library containing data connections is configured as trusted in SharePoint Central Admin.
The Data Provider referenced in the Excel report (MSOLAP.5) is configured as trusted in SharePoint Central Admin.
In the Excel report, the Excel Services authentication settings is set as "use authenticated user's account". This wortks fine in the DEV environment.
Concerning SecureStore, PowerPivot Configurator has configured it the PowerPivotUnnattendedAccount application ID in all the environments. There is
NO configuration of an Application ID for Excel Services in any of the environments (Dev, test or production). Altough I reckon this is where the solution lies, I am not 100% sure as to why it fails in test and prod. But as I read what I am
writing, I reckon this is because of the authentication "hops" through servers. Am I right in my assumption?
Could someone please advise what am I doing wrong in this case? If it is the fact that I am missing an Secure Store entry for Excel Services, I am wondering if someone could advise me on how to set ip up? My confusion is around the "Target Application
Type" setting.
Thank you for your time.
Regards,
P.

Hi Rameshwar,
PowerPivot workbooks contain embedded data connections. To support workbook interaction through slicers and filters, Excel Services must be configured to allow external data access through embedded connection information. External data access is required
for retrieving PowerPivot data that is loaded on PowerPivot servers in the farm. Please refer to the steps below to solve this issue:
In Central Administration, in Application Management, click Manage service applications.
Click Excel Services Application.
Click Trusted File Location.
Click http:// or the location you want to configure.
In External Data, in Allow External Data, click Trusted data connection libraries and embedded.
Click OK.
For more information, please see:
Create a trusted location for PowerPivot sites in Central Administration:
http://msdn.microsoft.com/en-us/library/ee637428.aspx
Another reason is Excel Services returns this error when you query PowerPivot data in an Excel workbook that is published to SharePoint, and the SharePoint environment does not have a PowerPivot for SharePoint server, or the SQL Server Analysis
Services (PowerPivot) service is stopped. Please check this document:
http://technet.microsoft.com/en-us/library/ff487858(v=sql.110).aspx
Finally, here is a good article regarding how to troubleshoot PowerPivot data refresh for your reference. Please see:

Sharepoint 2013 Excel External Data Source Refresh Issue

I have been facing this issue for quite some time now.. i have created an Excel sheet in Excel-13 and have imported data from an external data source [SQL server 2012].
Everything is working fine, with the excel sheet on the desktop. Data refreshes, every-time i open the excel file and also at regular intervals that i have configured in the data source properties.
The problem begins when i save that excel sheet on my sharepoint server. the issues that i am facing are :
1. Changes made into the original data source, are not reflected immediately inside the excel sheet inside the browser. after 5-10 minutes, it reflects the changes..
2. The data doesn't refreshes automatically. After i update my data inside the sql server table, i have to manually trigger the refresh of the data connection when viewing the excel sheet inside the browser, even though i have marked "Refresh when opening
the file", and refresh every 1 minute inside the excel sheet. Any solutions ??
I have been troubled a lot by this issue, and seek for some quick solution.. Any help here ??

I found the solution finally, my self ..
Issue - 1 : It's going to take atleat 5-minutes to refresh the data connection, that is generally not a big time span.
Issue - 2 :
--> Set Your connection to refresh everytime the file is opened. go to internet explorer -> file -> internet options -> general -> Browsing History -> Settings -> Check for newer versions of stored pages... Check 'Every time I visit the
webpage'.
Now everytime i update your original data source, wait for 5-10 minutes and refresh my web page containing the excel sheet.. The Contents of the excel sheet are updated as desired..

How do I remap fields in Visio shapes when pointing to an external data source?

Hi,
I'm creating an organizational chart (org chart) in Visio. It refers to a SharePoint list. in the SharePoint list there is a column called FullName. This is the one I want to map to the Name field in a Visio shape. How do I remap fields in Visio shapes when
pointing to an external data source?

Mark,
Unfortunately the required field/column names are hard coded in the add-in.

Can you include an external data source in query condition?

Hi all,
I have a user that wants to run a report off a subset keys in an external data source. Is this possible in Disco Plus?
For example, he has an Excel file that is just a list of employee numbers. He then wants his Disco query to only bring back the employee records for the people listed in the Excel file. Right now, he uses Cognos and can do this. A visual representation of this would be a condiition that would accomplish something like this:
WHERE EMPLOYEE_NUMBER IN (Excel row 1, Excel row 2, Excel row 3, ...)
We do not want to have to load the data into a table each time to accomplish this, but no other way readily jumps out at me. Anyone have any ideas?
Thanks in advance,
Jewell

Jewell.
Given the situation you describe, I don't know of any 'reasonable' way to do this either the GUI in Desktop or the interface in Plus.
However - and just for the grins - there may be a possibility if done through the command line interface of Desktop. I truly doubt you'll want to do it - given the limitations - but ...
... in the command line interface you can put in the switch for /parameter such as: /parameter today trunc(SYSDATE), which means that your report is looking for a parameter called 'today' and you're putting in the data to put in the parameter 'trunc(SYSDATE)'.
So, you could either build the command line with a batchy-kinda-process in that via batch it reads a file as input and puts parameters, or hard code it manually (which no one would want to do). Problem is, if you have multiple values, I don't think it'd work as you're saying something like:
/parameter today (SYSDATE,SYSDATE-1,SYSDATE+!) - which I doubt would work as it probably only wants one value
or if you had:
/parameter today SYSDATE /parameter today SYSDATE-1 /parameter today SYSDATE+1
it also might choke.
Alternatively, you could investigate using Plus with the Java command line utility and see if it's possible to do a similar thing via Java.
... so long answer to a short question ... (my specialty) 8-)

UCCX 10 CUIC Custom Report (using external data source)

Hi.
We have a customer where we are storing information in an external data source. We would like to built a report and import that report into their UCCX CUIC System in order for the customer to have the new report along side with the UCCX built-in reports. We need to add the external data source to CUIC but I'm not sure if the strip CUIC version of UCCX can allow that. Is that possible?
I know that with CUIC Premium we can add third party data sources into the CUIC. The Premium CUIC NFR allows that and we can create the report but for it to work in UCCX we need to add the external data source to CUIC.
What are my options? If any?
Thanks in advanced,
-Jose

Hi Jose,
You can basically build custom reports on a standalone CUIC server and import them to the CUIC on UCCX.
But I am not sure if this datasource is continuously polling information from the DB and giving it to the report and if this is possible.
Please refer to the link below for creating the custom reports on CUIC in UCCX:

Web Analyzer - ability to access external data sources?

Documentation on help.sap.com for the 2004s Web Analyzer notes it can render queries, query views, infoproviders, and <b>external data sources</b> for ad-hoc analysis in the standardized reporting template.
Can anyone clarify exactly what constitutes external data? To my knowledge, I didn't think it was possible to report on something outside of the BI instance (let's say an Oracle table on another server, for example).
Thanks in advance for your help.

Hi Scott,
in the Web Analyzer you can use external OLAP data sources(ODBO or XMLA) . Relational data sources are not supported in NW2004s.
You can set this up in the portal system landscape.
Please have a look on
http://help.sap.com/saphelp_nw2004s/helpdata/de/8e/020597f9b4486492e69283fab424fa/frameset.htm
and
http://help.sap.com/saphelp_nw2004s/helpdata/de/8e/020597f9b4486492e69283fab424fa/frameset.htm
Depending on the data source different capabilities are supported, so that some options are only available when you are using the BI OLAP Processor and won't be supported when using external data sources.

Add external data sources to Webi 4.1 (xls, txt)

Hello,
What is the best way (if any) to allow my users to add in their external data sources to Web Intelligence 4.1? So that they can join this with Universes or just create stand alone Webi reports from their own External sources like Excel spreadsheets, .TXT or CSV files?
Thanks,
Matt

Thanks for the feedback,
We are actually using 4.1.1 (service pack 1) and when I'm logged in as the Administrator with 'Full Control' to Webi I only can select the following data sources (see attached):
- No data source
- Universe
- BEx
- Analysis View
I can upload both Excel Files and Text Files to Webi no problem via --> Documents --> New Local Document but can't seem to access either of them by using any of the above data source selections.
With 4.1.1 is there another access level or privilege I need to enable to allow folks to get at external sources? If so, how?
THANKS,
Matt

Lookups to External Data Sources

Is it possible to create data object lookup fields that point to data objects that are External Data Sources rather than Internal Data Objects.
Thanks,
Mark.

Thanks for you reply Matt.
Yes I did mean creating lookup fields to External Data Objects. I believe our issue is actually that we were trying to create a lookup from an External Data Object to another External Data Object - which doesn't seem to work.
We have confirmed that we can lookup from an Internal Data Object to an External Data Object which will cater for the majority of the use cases. For any other cases (external looking up external) we will produce a new Internal Data Object and flatten out the lookup levels.

SPM : Integration with External Data Sources

Dear Experts,
Can you let me know with your comments or by sharing any link or documentation, as to how to Integrate SPM with External Data Sources.
And how many or what all external Data Sources, can SPM Connect with ?
Regards
Pankaj

Hi Pankaj,
There are no limitations of external data you can bring into BW and visualise in the SPM UI - you can expose custom bex queries as "datasources" in the user interface, and these can show anything you like. Its just a question about what makes sense to show in SPM.
Are you looking to bring in anything specific?
Thanks

How to write data/result in excel or external data source in c#??

Hello Team,
I have automation framework in c#. So there are multiple testmethod and testclasses.....so i havt to write result of every testmethod ...in below format..in excel
[TestMethod]
public void Demo()
WriteIntoExcel("TestClassName","TestmethodName", Pass/Fail, Time);
I can all info in every methods but i dont know how to write it in excel or any other external datasource after every method .....
Actually i want c# code to which will write data/result in excel ...excel might be saved in shared drive...
Thanks in advance

Hi Mon,
We also could use OleDbConnection to insert data into excel.
using System.Data.OleDb;
using Excel = Microsoft.Office.Interop.Excel;
using Microsoft.Office.Interop;
//in the method section use as :
string datevariable = "02/02/2010";
string namevariable = "Shyam";
string strConnectionString ="";
string cmd;
string filepath = ""C:\\sample.xls";
strConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+filePath+@";Extended Properties=""Excel 8.0;HDR=Yes;""" ;
OleDbConnection conn =new OleDbConnection (strConnectionString);
try
conn.Open();
catch(Exception e)
Console.WriteLine(e);
try
// Insert into Sheetname
cmd = "Insert into [Sheet1$] ( [Date], [Name]) values ('" +datevariable+ "','" +namevariable+ "');
//Similarly you can update also
OleDbCommand cmdUpd=new OleDbCommand(cmd);
cmdUpd.Connection = conn;
cmdUpd.ExecuteNonQuery();
conn.Close();
catch(Exception e)
Console.WriteLine(e);
