Refreshing data model in AIR

This is probably one of those problems where you toil and
slave for hours to find out it is something stupid, but I am at my
wits end.
I am constructing an AIR App that uses a data model to
retrieve data from a php script that generates an XML string. The
mxml string for the model and the grid, respectively :
<mx:Model id="listingsDataGrid" source="
http://127.0.0.1/cmsbe/sql2xml.php"/>
<mx:DataGrid id="dg" width="100%" height="100%"
dataProvider="{listingsDataGrid.listing}" top="0" >
I have this XML displayed in the data grid, but I am not able
to make the grid refresh. I tried to have a button that forced a
refresh with the following:
<mx:Button label="refresh"
click="listingsDataGrid.refresh"/>
When I point my browser to the PHP script listed for the
model source above, the desired (and refreshed) XML string is
displayed, but no matter how many times I try to refresh it from
within my AIR app or how many times I re-launch the project from
within Flex Builder I cannot get the info to refresh. If I publish
the application and re-install it on my system the grid reflects
the latest XML data, but it then does not refresh again.
There seems to be little documentation on the
<mx:Model> way of doing things, and while I could probably
use a URLRequest method to retrieve the XML with a little bit more
power, I would like to stick with this simpler <mx:Model>
method.
It almost seems as if it is a caching problem, but I have
done everything possible to force no caching with the PHP script
itself, and the fact that it is updated each time when I point my
browser to the PHP script seems to indicate the problem is not
server-side.
I have googled this to death with no results... any
suggestions? Thanks in advance!
If I need to post more/better info, just let me
know...

I don't know much about data models, but this is a common
problem in flex when it comes to using httpservices. Once an
httpservice with a method of get returns one result, it will not
refresh. The answer with httpservice is to change the method to
post, and put a dummy variable in the post request. I do not know
how you would fix this when using a model, but you might try
changing to httpservice. There is more about this problem in the
context of httpservices over on the flex board.

Problem in refreshing data model

Hi,
I am struggling in solving this issue for quite some time. I am developing a fusion web application using Jdeveloper 11.1.2.
I have 3 view objects groups,employees and dependents. All the three view objects have binding variables and view criteria. The three view objects are linked using view links. The following shows the structure of the application module.
Groups--------- binding variables: GrpID, GrpName
------Employees ---------- binding variables: EmpID,EmpName
---------Dependents---------------binding variables: DepID and DepName
Now Groups and Employees are linked using GrpEmpViewLnk. Employees and Dependents are linked using EmpDepViewLink.
I have a page which acts like a search form which has fields like GroupID, EmpId and DepID with corresponding buttons named "find" to look up information.
When I try to set the GrpId at Groups VO, the data model is populating correctly with the rite employees and dependents.
When I try to set the EmpID at Employees VO, the data model has incorrect data. I looked at the query to see whats happening. Along with setting the bind variables EmpID,EmpName for Employees VO, a bind variable from the view link EmpDepViewLink is also being passed. I don't have any idea of how to control the value that's being passed through the view link.
Could someone please help me in resolving this issue. I can provide more info on this issue.
Thanks!
Shai.

If you want to query Ephraim without dependency on a specific group, then you need to have it as an idependent go in your data model and not nested under group. Right now you'll be querying the empty in a specific group.

Excel Workbook with Excel Data Model stored on SharePoint - daily refresh

I'm not sure if this is exactly the right forum but I'm hoping that someone here can either answer or point me in the right direction.
I have an Excel Workbook with an Excel Data Model.
The Excel Data Model uses SQL to contact our data warehouse and pull through data into tables.
We are storing the Workbook on a SharePoint site and viewing it using Excel Services.
The data in our data warehouse is updated daily and so I would like to refresh the workbook daily and remove the option to refresh the data in the browser.
Is this possible with a workbook that has an Excel Data Model (I've seen lots of posts that relate to workbooks with connections to tabular models).
Thanks
Paul

PowerPivot removed table replicated into the data model on refresh

Hey
I am facing the following problem which is absolutely persistent and annoying in nature. I am using a data model created with PowerPivot with connections to three different SQL servers and 25 tables. The bug is that every time I refresh my data, a table
that was initially added to the data model (and later removed) is replicated in equivalent number of tables that use this connection, which is currently around 12 tables, so I get 12 duplicates of the same unnecessary table on every refresh, named with the
name of the schema on the SQL server that is followed by a running number. Removing these from the data model on every refresh simply takes too much time on a daily basis. The additional undesired table which is created is what is defined in the SQL query
of the connection string of this connection.
I tried to solve this problem by zipping the Excel file and modifying this SQL statement present in the connection string in the connections.xml file in a way that it would not return anything, but this always leads into a corrupted workbook.
After encountering this I have managed to avoid this problem by making sure that the initial table I'm adding to the data model will remain in the model, but I really don't want to rebuild this current model. Is there any fix for this issue without
rebuilding the data model?
Thanks for all the help in advance!

I am using 64-bit Office 2013 with the recent SP1 upgrade and the included PowerPivot plug-in on a Windows 8.1 machine.
I always create the connection by using "From SQL server" then fill in the server and log in details and use a ready SQL statement that I have written by using SQL Server Management Studio to import the initial table. For all the preceding tables
using the same server and schema, I always select it from existing connections and just paste the SQL queries required for any additional tables to the "Write a query that will specify the data to import", rather than using the table import tool.
I am not sure if it could have any effect that I've been using the type connection "From SQL server" although the database is really running on Azure (there is a possibility to select From Other sources > Microsoft SQL Azure, but the functionality
seems the same).
I don't really understand what I should edit from the existing connections section. Just to clarify, apparently the Connection String parameters can be edited from PowerPivot, but not the Command Text which can be viewed from Excel Data > Connections
> Properties, but is shown in gray with a message "Some properties cannot be changed because this connection was modified using the PowerPivot add-in."
In the data model I am using two sets of identical tables, but connected to two different servers that are running a database 1:1 in structure. Initially the problem considered only the other of these, but I accidentally reproduced it by, again, editing
the SQL query in the table that was initially imported when that connection was created (PowerPivot > Design > Table Properties). Now when refreshing I get tables that are structured as in what the "Connection Text" part of the connection would
produce, which replicated for the equivalent amount of additional tables using the same connection, so now I'm getting 12 tables (the number of tables using the same connection) each named "*schemaname1* Query", "*schemaname1* Query2",
"*schemaname1* Query3" "*schemaname2* Query" and so on.
Personally I can definitely see a pattern here. If there isn't a table matching what has been specified in the "Command Text" that was described when the connection was created, then it for some reason runs this query anyway on every table that
is using the connection.

Powerpivot Error on Refresh -- "We couldn't get data from the data model..."

I'm using Excel 2013 and Windows 8.1. I have a spreadsheet I've been using for over a year, and I've just started getting this error message when I try to refresh the data.
"We couldn't get data from the Data Model. Here's the error message we got:
The 'attributeRelationship' with 'AttributeID' - 'PuttDistCat9' doesn't exist in the collection"
Any idea how I can fix this problem? I haven't changed anything related to that particular attribute. All the data is contained in separate sheets in the workbook, so there are no external sources of data.
Thanks.
Jean

Thanks for all the suggestions.
I found a slightly older version of the spreadsheet that still refreshes properly, so I don't think I have any issues with the version of Excel or Power Query. (I've had this same error before, and I believe I applied the hotfix at that time.)
I think this problem started after I updated a number of the date filters in the pivot tables. I haven't made any changes to the data model, and the only updates I've made were to add data (which I do all the time), and to change the date filters on
the pivot tables.
As suggested, I added a new pivot table querying one table (the table with the attribute that shows up in the error message), and it worked fine. I can also refresh this pivot table.
Then I tried adding a pivot table which went against several tables in the data model (including the table in question). The pivot table seemed to return that data properly. However, when I tried to refresh it, I got the same error message ("we
couldn't get data from the data model...").
Dany also suggested running the queries one at a time to see which one is in error. Without checking all the pivot tables, it appears that any which use the table "HolePlayedStrokes" generate the error (this is the table with the attribute
mentioned in the error message). Pivot Tables without that particular table seem to refresh OK. Unfortunately, that is the main table in my data model, so most of the pivot tables use it.
Any other suggestions? I'd be happy to send a copy of the spreadsheet.
Thanks for all the help.

Data Refresh Error: We cannot locate a server to load the workbook Data Model.

Hello,
Recently I have developed a PowerBI Report using Excel Workbook with external data source. It refreshes successfully for some days and then starts throwing error on every scheduled refresh as "We cannot locate a server to load the workbook Data
Model."
The workaround solution is to restart the application server which has SQL Server Power Pivot Services Installed which will again work for some more days and again start throwing error.
So, I am looking for permanent fix for it.
Following are additional details about our SP Farm:
No. of front end servers: 2, Application servers:2, DB servers 2 with windows fail over cluster.
PowerPivot Server is installed and configured from App 2 server.

PowerPivot Data Refresh Fails - We cannot locate a server to load the workbook Data Model

Hello,
I have installed sql01\PowerPivot instance of Analysis services on my existing SQL Server and configured it per Configure Power Pivot for SharePoint 2013
http://technet.microsoft.com/en-us/library/dn456880(v=office.15).aspx . I did not install a second Database Engine on the server.
I created an Excel 2013 workbook using the Excel 2013 PowerPivot add-in and saved it to my SharePoint BI Center Document library.
When I try to refresh my workbook, I get 2 errors in the SharePoint log.
http://support.microsoft.com/kb/2756665?wa=wsignin1.0 indicates the sproc is deprecated, but that does not help me fix the issue.
Log errors:
Following error occured while trying to execute a sql query: System.Data.SqlClient.SqlException (0x80131904):

EXCEPTION: NoAvailableStreamingServerException: We cannot locate a server to load the workbook Data Model.

Hi Marcel,
Based on my research, it seems that you have Microsoft SQL Server 2012 PowerPivot for SharePoint 2013 add-in installed on a computer. When you perform a data refresh operation on some PowerPivot workbooks in Microsoft SharePoint 2013, you receive two error
message.
As to the first error, this issue occurs because the Custom Properties on the Excel workbook are not correctly cleared before you set a new serialized schedule. This causes an extra custom property to remain after you set the new schedule. Therefore, the
new schedule fails. To fix this issue, please
install Cumulative Update 9 for SQL Server 2012 SP1.
As to the second error, please
running a repair using PowerPivot configuration wizard for SharePoint 2013. For more information about Troubleshooting PowerPivot Data Refresh, please see:

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.

PowerPivot data model as Source on Cloud

Hi All,
We have an excel workbook with a heavy powerpivot model. Can we use any Cloud services to segregate the powerpivot model and use it as a data source?
We have already accessed the PowerPivot Gallery on Sharepoint(On-Premise) and Tabular Cube solutions but both of them are On-Premise solutions and since we need a Cloud based solution; we have rejected both of them.
Also, regarding Cloud solution(if there's any), will it answer the following problem statements:-
Will it be possible to drive a light weight excel report by Powerpivot data model?
On Premise database based report refresh (using gateway)?
PowerPivot /Calculated Measures – will they be visible through data model?
Regards,
Amit

This is not currently possible, but I understand that it is in the works.

Data Model won't open

I have created a PowerPivot data model using Excel 2013. It runs fine on my computer (the one where I built it), but will not open in other computers. All computers have the same 64 bit version of PowerPivot 2013 and run on Windows 8.
The primary data model table contains about 170,000 rows, 20 raw data columns, 2 calculated columns, 30 calculated fields (measures), and there are also a couple of small linked-back data tables with relationships to the primary
table. The data model takes approximately 5 minutes to refresh using my computer when I click 'Update All' (pertains to linked-back tables) on the PowerPivot ribbon in Excel. 99% of that 5 minutes is spent reading the data. However the
refresh time is not really my concern, as the data model will not open at all on any other computer.
It might be worth mentioning that my data model utilizes the 'stdev.p' function (new to PowerPivot 2013). However, I would not expect this to matter since all computers I am trying to run on have PowerPivot 2013.

User, are you still looking for the answer?

Problem connecting PowerPivot's (Office 2013) Data Model deployed on SharePoint 2013 to data source.

Hi Jeff,
Firstly, I need to confirm whether you are refreshing Data connection in browser, since Data Refresh is not supported in Office Web Apps. Please refer more information in this article:
http://blogs.technet.com/b/excel_services__powerpivot_for_sharepoint_support_blog/archive/2013/01/31/powerpivot-for-sharepoint-browser-refresh-fails-data-refresh-not-supported-in-office-web-apps.aspx
From the error "Call to Excel Services returned an error", please verify the location of the
data source, for example an Excel workbook, is registered as a trusted location with Excel Services:
https://technet.microsoft.com/en-us/library/jj219699(v=office.15).aspx
Since you are using unattended account for Excel Services to connect from SP to databases, I wonder if the issue occurs to unattended referesh, if so, please refer to:

How to get data model to recognize structure change

I have an extremely complex report that was built almost entirely manually -- except for using the Data Wizard to create the Data Model (multiple queries with multiple groups). The source view that the query Q-1 is based on has changed. It is a change in the precision of the column. How do I get the data model to notice that change? The Width in the Property Palette is still showing 8 when it should now be 16. This is causing the display on the report to be truncated to 8 characters.
I don't want to have to rebuild the data model. It took me 3 days to get it so that it works!
Thanks

PLS OPEN THE QUERY AND THEN CONNECT USING YOUR USER. I THINK WHEN YOU REFRESH THE QUERY AND CONNECT THEN WIDTH IS CHANGE AS THE COLUMN IN THE DATABASE.(i.e. 16)
THANKS,
FAROOQ Thanks for the suggestion. Unfortunately, the same thing happens when I do this as happens if I modify the query with a space (as before); the rows are removed from their groups, and I lose the Source of my calculated fields.
If anyone is interested, I finally found a way to do this:
1. Convert the report into a text file (File>Administration>Convert);
2. open the text file in a text editor;
change the offensive WIDTH settings (make sure to look for all of them);
3. save the text file;
4. then convert it back to a RDF file using the converter.
A round-about way to perform what should be an automatic operation -- but there it is.

BIP Trial 11.1.1..6: Error while generating XML data in Data Model

Hello,
I have created a Data Model with a single query. After saving the DM and clicking on the XML icon to generate sample data, I get the following error:
The XML page cannot be displayed
Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later.
End tag 'span' does not match the start tag 'img'. Error processing resource 'http://localhost:7001/xmlpserver/servlet/xdo'...
*<table style='background=color: #d9e5ef; margin-top: 10px;' width='100%' cellspacing='0' cellpadding='0' border='0' summa...*
I have verified that the SQL runs without errors in SQL Developer using the same connection parameters as whats used in the DM.
There are no html tags/key-words etc being used in the sql our it's output.
Is there a a way to debug this? This is extremely frustrating. Especially since the same sql works without any issues in Oracle Reports.

ya i can understand we wont do the sql logic at the data model part as some time performance issue may come when comparaed to sql run in package and sql running in data model . so i have mostly done using package and i will just do select * from table in the data set of data model so i didn't face any issue's like this .
once check this tutorial may be you already

How can I find out what is causing this error in SQL Developer Data Modeler

Friends,
I am trying to import entities into into SQL Developer Data Modeler from Oracle Designer 10.1.2.3.
In case of need I perform these steps to perform the import:
File --> Import --> Oracle Designer Model --> Select database connection --> Select work area --> select application system --> select one entity --> Click finish --> Import starts
During the import process I see an alert dialog box with the message:
There are errors in import - check Log file Clicking Ok dismisses the alert box and I see the following summary screen:
Oracle SQL Developer Data Modeler Version: 2.0.0 Build: 584
Oracle SQL Developer Data Modeler Import Log

          Failed Statements:           0
          Not Recognized Statements:      0The Entity is then displayed in the Logical View within SQL Developer Data Modeler.
Upon checking the log file I see the following entry:

Thanks in advance for any help you may be able to provide.

No this helps a lot. It's not strange. Firstly, in a versioned repository you should see Private Workareas and Shared workareas, so your workarea may be in either of these. It won't be in the Global Shared Workarea, as this only for non-versioned repositories. (I like to open the RON by selecting the full Repository, that way I can see the private and shared worlareas and the configuration and containers all in the same tree.
Now your workarea is defined by a set of rules, so when you expand the workarea in the RON, and select the object, then that's the workarea and object you'll see in the import dialog in the Data Modeler. So if you check it out and check it back in, and can't see it in the RON, then the rule is not seeing this object. (Did you refresh the workarea in the RON?) If you can't see it in the RON, you can't see it in the Data Modeler. If you're working in a versioned repository, you need to work in the specific work area, i.e V27 and this is what you need to select in the Data Modeler.
It looks like you are selecting the wrong workarea in the Data Modeler.

Using CVS in SQL Developer for Data Modeler changes.

Hi,
I am fairly new to SQL Developer Data Modeler and associated version control mechanisms.
I am prototyping the storage of database designs and version control for the same, using the Data Modeler within SQL Developer. I have SQL Developer version 3.1.07.42 and I have also installed the CVS extension.
I can connect to our CVS server through sspi protocol and external CVS executable and am able to check out modules.
Below is the scenario where I am facing some issue:
I open the design from the checked out module and make changes and save it. In the File navigator, I look for the files that have been modified or added newly.
This behaves rather inconsistently in the sense that even after clicking on refresh button, sometimes it does not get refreshed. Next I try to look for the changes in Pending Changes(CVS) window. According to the other posts, I am supposed to look at the View - Data Modeler - Pending Changes window for data modeler changes but that shows up empty always( I am not sure if it is only tied to Subversion). But I do see the modified files/ files to be added to CVS under Versioning - CVS - Pending Changes window. The issue is that when I click on the refresh button in the window, all the files just vanish and all the counts show 0. Strangely if I go to Tools - Preferences - Versioning - CVS and just click OK, the pending changes window gets populated again( the counts are inconsistent at times).
I believe this issue is fixed and should work correctly in 3.1.07.42 but it does not seem to be case.
Also, I m not sure if I can use this CVS functionality available in SQL Dev for data modeler or should I be using an external client such as Wincvs for check in/ check out.
Please help.
Thanks

Hi Joop,
I think you will find that in Data Modeler's Physical Model tree the same icons are used for temporary Tables and Materialized Views as in SQL Developer.
