SharePoint Designer 2010 External Content Types Data Source Already Exists in Business Data Connecti

Posted By:      Posted Date: September 23, 2010    Points: 0   Category :SharePoint
 

I used the Secure Store to create connection in SharePoint 2010 Designer External Content Types Data Source Explorer.  Later I changed some column names in the table.  I deleted the connection from Data Source Explorer and recreated it. I right clicked on the table and selected Create All Operations. When I clicked the Finish button, I got "The system definition with the same name as this data source already exists in the Business Data Connectivity Metadata Store and it refers to a different data source.  Cannot complete operation generation.  Add a connection to this data source with a different name and try again." 

I re-created the Secure Store using a different name in SharePoint 2010 Central Administration.  I didn't find the option to choose the connection name in SharePoint 2010 Designer. After I clicked Add Connection, I entered the Database Server and the Database Name, selected Connect with Impersonated Window Identity, entered Secure Store name, and clicked OK. The connection created with the database name as before.

SharePoint Designer 2010: Business data connectivity metadata store is unavailable

  
Running SharePoint Server 2010 RTM. Fresh install in production not via the wizard but a vanilla install and bringing services up one by one. Just brought up the Business Data Connectivity Service. Other services currently up are Managed Metadata Service and User Profile Service. Two web applications with services deployed to both web applications. The scenario below holds true when connecting to a site on either web application. 1) Open a site, i.e., root portal site, in SharePoint Designer 2010 2) Click External Content Types. Error returned: "The Business Data Connectivity Metadata Store is currently unavailable" is returned. 3) Click Ok then click New | External Content Type. Error returned "THe server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults...". The Business Data Connectivity Service status in Central Administration is Started. Any ideas?

SharePoint 2010 External Content Type and InfoPath 2010 - Numeric data type fields missing in InfoPa

  

Connected SQL data table to SP 2010 ECT from SQL table.  The SQL table has several fields that have a type of "numeric(3,0)".  The SP 2010 list shows all fields form SQL.  When we open up InfoPath Designer and reference the SP List data (from SQL) all of our numer fields are missing from the available fields list.

I amd going to try another data type but that hardly feels like a solution.  If anyone has any ideas please let me know!

Microsoft Excel and Sharepoint KPI's (External Data Source)

  
This is my first post i hope i get a clear answer for my question. I recenty have been working on KPI's drawn from Microsoft Excel documents that i created. However, as we know, external data sources in excel don't work with sharepoint. If that was possible it would have saved the company a lot of time and effort My questions are: Is there any way to have external data sources with some advanced modifications, or any other way that would simulate this process? (External data update) Can i directly update my data by tampering the database where the excel file is saved?   I don't know if the files uploaded in sharepoint are stored in a database, so i want some validation around this. (Name of the database, path etc.)   Hope you can shed some light to my questions Thanks in advance Theo

Data View Web Part in SharePoint Designer 2010

  
Is Data View Web Part (aka Data Form Web Part) in the SharePoint 2010 has changed from the SharePoint 2007 or Is it working differently in the SharePoint Designer 2010? In SharePoint Designer 2007, whenever you have data view web part on the page, there is little handle to click on the top right of the data view web part to show Common Common Data View Tasks. Also for each cell, there was a handle to show xsl:value-of tasks which was great for formatting. Is that option is gone in the SharePoint Designer 2010?

I've created a basic WCF service using an edmx model and service class that only contains the code below (takes 10mins to set up). I followed this link as instructions http://msdn.microsoft.com/en-us/data/cc745957.aspx

public class GRef_Service : DataService<MasterDataDirectoryEntities>
{
  // This method is called only once to initialize service-wide policies.
  public static void InitializeService(IDataServiceConfiguration config)
  {
    // TODO: set rules to indicate which entity sets and service operations are visible, updatable, etc.
    // Examples:
    config.SetEntitySetAccessRule("*" , EntitySetRights.AllRead);
    // config.SetServiceOperationAccessRule("MyServiceOperation", ServiceOperationRights.All);
    //config.SetServiceOperationAccessRule("GRef_Building", ServiceOperationRights.AllRead);
