Linking external data to a Timeline shape - help!

Hello,
I have a number of ODC files from Project Server that I can use as a Data Connection in VIsio.
As you might expect, a number of columns pull through by default from the ODC - columns titled like Project Start, Baseline 1 Start, Baseline 6 Start etc.
I understand that each of the Timeline shapes in Visio "expects" columns to be called a certain way for its input.
For example, a timeline shape (e.g. Block) expects to have as input column names of "Start" and "Finish". I can quite happily amend, say, the default column names Project Start and Project Finish to just Start and Finish,
and the timeline shape can quite happily amend itself to the values in those columns.
However -- when I want to put a Milestone (e.g. Diamond) onto this timeline, it seems that the Milestone shape also expects column(s) named a certain way as its input.
My question is then: what is the input it requires in terms of column name? If it is indeed to be a column "Start", how do I get around this? Given that I've already renamed a column to Start for the
timeline start, I would then want to rename say, Baseline 6 Start to
Start for the milestone shape, but I can't have two columns named the same?
Or: can I say to the Milestone shape - "hey, I have a milestone date in a column called x. I know you want to look in a column called y to find out the date of the milestone, but can you look in column named x instead?"
Many thanks!

Hi,
you can import the same data once again. It creates the new data record set in Visio. rename the column names and map to the corresponding timeline Shapes.

BPC 7.5NW External Data Links

Hi All u2013
This question is in regards to a BPC 7.5 NW (SP8) input schedule stored in BPC with externally linked MS Excel 2007 spreadsheets stored outside BPC.
I have built an input schedule (which is stored in a team folder) and linked external excel spreadsheets into the schedule. My EVDRE is in Sheet1. Sheets2 u2013 5 contain the links to my non-BPC workbooks.
My problem is that when I use the u201CSend and Refresh Schedulesu201D u2013 u201CActive worksheetu201D, multiple windows pop-up for updating the links in the non-active (external data linked) worksheets. Does anyone have a better way to link data external to BPC in a schedule or report? If not, is there a way to stop these pop-ups?
Thank you!

Hi,
Can you try as follows:
workbook options> Refresh Options> Check EVDRE : Refresh by Sheet.
Hope it helps..

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?

Dashboard with Webi Report link - Cannot access external data

Dear Gurus,
I've a dashboard with access to WEBI report for Language setting.
All works fine for the group: Administrators.
If I take the Users out of the Adminstrators group and assign them normal power user group, I get the message that the external data cannot be accessed. No Error # or so is displayed.
Even if I grant the usergroup Full Control / Power User on the
Universe,
the Connection
Dashboard itself,
WEBI Application
Webservices
Still it does not work.
As far as I can see is, that it can't be a Network (Firewall)-Problem, because it works for the memebers of the Adminstration groups - What else can it be?
I've attached the screen shot for your reference

External Data Refresh Failed. We cannot locate a server to load the workbook Data Model. ThisWorkBookDataModel

Hi All,
I have been trying to fix this for days now. I have tried solutions in many articles but to no avail. So while the error message is something you may have seen may times, I just can't find a solution in my case.
This is the error:
And in text just in case the image isn't viewable:
"External Data Refresh Failed. We cannot locate a server to load the workbook Data Model. We were unable to refresh one or more data connections in this workbook. The following connections failed to refresh: ThisWorkBookDataModel."
What is worse is I have checked the ULS (SharePoint Trace Logs), the Event Viewer Logs and the OWA Logs and I cannot find a specific error that would help pin point the problem.
Excel Workbook
So what am I doing? I have an Excel 2013 workbook and I create an "SQL Server" connection to the AdventureWorksDW database, add a pivot table and a pivot chart, test in in Excel and all works fine.
I save the Excel workbook to SharePoint 2013 and then select "Data" then "Refresh All Connections" and then I get the error in the picture above.
Even more puzzling is I have another Excel workbook that also has pivot tables and pivot charts in the AdventureWorksDW2012Multidimensional cube database in "SQL Analysis Services" and this works fine. Hmmm.
My Environment
My environment is Windows 2008 R2 Server, SharePoint 2013 with the April Service Pack1 and a separate server with OWA2013 SP1. It has an SQL Server 2008 R2 database which has been upgraded to SQL Server 2012.
Data Model Settings
In Excel Services this is set to my server name which is "server-name". As I do not have instances all I can enter is the server name. As this works everywhere else including the workbook outside of SharePoint I do not think this is the problem.
But I could be wrong.
Unattended Account
I have set this up for the PowerPivot Services App and Excel Services App.
ODC Connections in Excel
I have tried all 3 authentication modes, Windows, Secure Store ID and "None" which is the unattended account. I have not tried the other connection types, should I?
Not in WOPI
I am not in WOPI mode.
AD Accounts
I have added permissions in the SharePoint Services and SQL Server, and as they work in Excel outside of SharePoint, I do not think it is a permissions issue. I could be wrong of course, but the problem is in one of SharePoint, OWA, AD,
SQL Server, Excel, and Windows Server.
Isolate the Error
Below is a list of errors I think are relevant but they do not tell me much. The SharePoint logs are not really giving me an error that tells me what to do and where to do it, or even why it cannot refresh, (perhaps not noticeable by the untrained eye).
Problem with SQL Server Not Analysis Services
So my cube database in analysis services works fine in SharePoint/OWA but not the databases in sql server. This is my best clue but I have no idea what it means. Why would it work with an Analysis Services connection but not an "SQL Server" connection?
It Works Outside of SharePoint
If I run the excel worksheet outside of SharePoint all works fine. When inside OWA this is where the refresh error occurs.
Errors from Event Viewer on SharePoint Server using ULS Viewer
"Failed to create an external connection or execute a query. Provider message: There are no servers available or actively being initialized., ConnectionName: , Workbook:"
"Refresh failed for 'ThisWorkbookDataModel' in the workbook 'http://server...'. [Session: 1.V22.26itT0lx8piNFeqtuGVhN214.5.en-US5.en-US36.98c0e158-9113-46e9-850e-edda81d9ed1c1.A1.N User: 0#.w|ad\testuser1]"
And an error in the ULS under the "Data Model" category:
"--> Check Deployment Mode (server-name): Fail (Expected: SharePoint, Actual: Multidimensional)."
This last error, as it turned out, defined the problem concisely, although I was yet to work out what it meant in some detail.

I finally solved this myself (or should I say with the help of several key articles).
The refresh did not work because the database was not in "SharePoint Mode". Yes, SQL Server has modes, 3 of them in fact.
If you installed SharePoint to the default SQL instance which would be called <servername> then you cannot use this default instance for Excel 2013 workbooks in OWA 2013 because the refresh only works if the database is in SharePoint mode.
So what are these 3 modes? The Deployment Mode property in the msmdsrv.ini file has them as:
0 = Multidimensional mode (the default whenever you install SQL Server normally)
1 = PowerPivot for SharePoint mode
2 = Tabular mode mode
How do you know what mode you are in? That's easy, open SQL Studio Manager and connect to all your SQL database engine instances (ignore Analysis Services or SSRS as they are not database engines). If you only have the default instance then that is almost
definately in Multidimensional mode which is the default and what SharePoint installs its databases to.
You must have an instance called <servername>\POWERPIVOT. This instance is the "sharepoint mode" needed, and the default instance name when you install an SQL instance in this mode.
If you don't see <servername>\POWERPIVOT in SQL server then you are not in "sharepoint mode". It is more accurate to say, you do not have an instance that is in sharepoint mode. This is because you cannot simply switch modes on an SQL server.
You have to install a new instance in the required mode, thats the only way.
That's easy enough. Load up the SQL Server setup CD and run setup. Install a brand new instance and select "SQL Server PowerPivot for SharePoint" when you get there in the wizard.
Now you will have the default instance that stores all the SharePoint databases and that is in mode 0, and a new instance called <servername>\POWERPIVOT that is in mode 1. The "<servername>\POWERPIVOT" instance connection is what you
will use for Excel 2013 when rendering in OWA 2013.
You also need to ensure OWA 2013 is not in WOPI mode for Excel worksheets. See the last link below for more information about WOPI.
Next you should go to the Excel Service App in CA and click Data Model Settings and add the <servername>\POWERPIVOT instance.
Then you have to either turn off the firewall on the SQL server machine, or create an inbound rule on the Windows firewall to open the TCP port for the <servername>\POWERPIVOT instance:
1. Start Task Manager and then click Services to get the PID of the MSOLAP$InstanceName.
2. Run netstat –ao –p TCP from the command line to view the TCP port information for that PID.
Finally, you can now create Excel 2013 workbooks that run in OWA without refresh errors, as long as you are connecting to the <servername>\POWERPIVOT instance. Hooray.

Load external data into se-main-menu

hi,
i've tried to load external data (vars,files)into a selfmade
sony-ericsson-flash-menu for the w810i.
it is possible to load the data for the current active menu
via loadVariablesNum("application://focused", 0);
so i thought i could load some other stuff into the mainmenu.
i tried to load an swf with loadMovie/loadMovieNum.
i tried to load vars from a txt-file with
loadVariables/loadVariablesNum.
and i tried to open a webadress with getURL.
but nothing happens ... :(
the files (swf,txt) are in the same folder like the
mainMenu.(tpa\preset\system\desktop\flash)
maybe the w810 does not execute the swf in the same folder
where it is at the moment?!
is it possible to figure out where the swf is executed?
the _url command is not supported by flash-lite-1.x ...
some ideas?

Accessing External Data from SharePoint 2010

I want to access external data from my SharePoint site.
I'm told that I need to follow these two articles.
http://msdn.microsoft.com/en-us/library/ff953161.aspx
http://msdn.microsoft.com/en-us/library/ff625800.aspx
I followed the first article but I get this error when I open the external list in my SharePoint site:
"Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Microsoft SharePoint Foundation-compatible HTML editor such as Microsoft SharePoint Designer. If the problem persists, contact your Web server administrator."
I don't know how to write a custom code
BTW I have installed PowerPivot on my SharePoint server.
Can someone please help me? I need to do this very quickly.

Hi,
Can you please elaborate whether the data you are getting is from excel file or from database.
1. If you are populating it from excel , then you can use the Excel service, Power pivot etc mechanism.
2. If you are getting it from SQL database then you can use BCS service application and use the OOTB external list and content type to display the same in your home page.

External Data Refresh failed - Unable to refresh list data in Excel Web Access WebPart

Hi,
I have created a PivotChart in Excel workbook that fetches data from a SharePoint list using "OData Data Feed". When refreshing the connection in Excel 2013, the updated data is displayed in PivotChart. But when i upload the same to a SharePoint
Library and refresh it through Excel Web Access WebPart, it throws an error.
After configuring PowerPivot for SharePoint, i am getting a "We cannot locate a server to load the Data Model" error.
Note -

PowerPivot Server has been under Data Model in Excel Service setting.
The library location is added in trusted zone.
Using secure store didn't fix the issue.

Hi,
For your issue, the possible reason is that the SharePoint environment does not have a PowerPivot for SharePoint server, or the SQL Server Analysis Services (PowerPivot) service is stopped.
Install PowerPivot for SharePoint or move the PowerPivot workbook to a SharePoint environment that has PowerPivot for SharePoint installed.
If the software is installed, verify that the SQL Server Analysis Services (PowerPivot) instance is running. Check Manage services on server in Central Administration. Also check the Services console application in Administrative Tools.

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.

Cannot add hub-managed content type with external list lookup columns to a list -- Error:Id field is not set on the external data field

This is a variation on the issue mentioned in this
post
We are using SP 2010 Content Hub to manage our content types. On the content hub we've created a couple of exteranl lists, and then created some site columns as lookups against these lists. We then added the columns to one of our content types
and set it to publish.
After the publishing job executed, I tried adding the content type (which now appears on the subscriber sites) to one of the document libraries on one of the subscriber sites. When I did that it threw the following error:

I checked the external content type configuration and it did specify an "id column". Anyone know if what I am attempting to do is possible and if so, what special configurations are required?
Thanks

The issue is not External Content type or external list but the look up column.
It's not possible to publish a look up column via the Content Type Hub.
If you need to do this then an alternate way is to use a Managed Metadata column instead, otherwise you will have to implement this via a feature.

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 :
