External Content Type not displaying List.

I am getting the following Error when i go to the External Content Type List i Created.
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.
When i open it up in Sharepoint Designer and look at the page i get this error.
soap:ServerException of type 'Microsoft.SharePoint.SoapServer.SoapServerException' was thrown.An error has occurred.
I'm connecting to a SQL Server with sql server credentials. I'm able to see the tables and columns in the Data Source Explorer.
The permissions for the Content Type are all authenticated Users with everything checked.

Hi,
How did you supply username and password to the external content type?
As i know, there are four options (user's identity, BDC's identity, impersonate windows identity, impersonate custom identity), you cannot directly input the SQL username and password.
I suggest you to use impersonate custom identity.
Before using it, you need to create a new target application ID in secure store service application. and select
user name and password for filed type at second step. after that, you need to set credentials for this target application ID to input your sql user name and password there.
Then you need to input this target application ID at connection properties (both default and client tabs) of the external content type.

Sharepoint 2013 and SSRS 2012 Integration - Report Server Content Types not displayed

Hello, Everyone:
I installed SSRS 2012 on our Sharepoint 2013 application server following the step-by-step instruction from the posting below:
http://msdn.microsoft.com/en-us/library/jj219068.aspx
Everything goes well after STEP 3 is completed.
I did see the reporting services started and SSRS service application created.
However, when I created a new site and tried to enable the predefined Reporting Services content types, I do not see the Shared data source (.rsds) files, report models (.smdl), and Report Builder report definition (.rdl) 3 types of files listed at
all.
Further more, when I go to the Provision Subscriptions and Alerts page, I keep getting a "SQL Server Agent state cannot be determined" error, even though the username and password provided is the admin user
for the database.
Any experience of what is wrong with the SSRS - Sharepoint integration? Please help!
Tina

Hello, Treavor:
Now that the content types problem is resolved, I need to come back to the
Provision Subscriptions and Alerts page.
I guess I'm a little confused about what is being asked for the Provision Subscriptions and Alerts page.
The user I provided on the Provision Subscriptions and Alerts page is my user-defined sysadmin role. And the page takes that.
When I downloaded the SQL script, it was trying to give the automatically generated user "sa-SPDevContentAppPo" permission.
Which user are we using to detect the SQL Server Agent?
Thanks again!

SharePoint 2010 Present Wrong Timezone for External List of External Content Type

External content is hosted on an independent SQL server DB from the SharePoint server. External content lists shows datetime fields 5 hours earlier as opposed to Eastern standard time but Web parts display data correctly.
Yes, timezones on both servers are correct. Timezones settings in SharePoint have been checked and all appear correct. There are several places for settings. Is there a checklist in case something was missed. Our SharePoint administrator has
looked for the cause and cannot determine.
I poured through other blogs and issues with external content and timezone on this site including "External Content Type Saving Dates in UTC".
Please provide a list for timezone settings such as global settings for a site, collection, external content, SharePoint 2010 designer settings, Central Administration settings, etc.

Hi Benjamin,
Please test the following approach for your issue, exporting the BDC Metadata Model from SharePoint Designer and change the normalization to use local time, and let us know the results.

Defining read operation on External content type

Hi,
I have used SharePoint designer to connect create an external content type to the lists.asmx web service on another sharepoint farm. On attempting to generate a read operation, I receive the following error. Any idea of how to fix this? is there any way
I can point to a single list as opposed to getting the methods for all the lists on the external sharepoint?
BTW, I am currently pointing to https://<soourceurl>/_vti_bin/lists.asmx

Restore SharePoint Database to new server - What to do about external content type?

I currently run SharePoint 2010 and have a content database back-up which I want to restore to a new server.
I was able to restore to a new server and everything seems to be working, except that I have one list in my previous site which had an external content type in it linking to a database for our ERP system. The ERP system's database will also be located on
the new server (same as the new location for the content database). How do I link the external content type from my list to the new location of the ERP database?
One thing which I've tried is to create a new BDC and set up a new external content type within the list. That seems to point to the new location just fine, except that I would have to remap all every single item in the list individually.
Any help would be appreciated.

You will need to modify your BCS Model to reflect the new location of your ERP database. Another option is to use SQL Aliases, which will allow SharePoint to think the new location is still by the old name.
http://mmman.itgroove.net/2012/07/setting-up-a-sql-server-alias-with-sharepoint-server-2010/
This is assuming that you are retiring the old database server.

External content type based on OData is not crawlable

Hi all,
I followed instructions from this msdn article
How to: Create an external content type from an OData source in SharePoint 2013. I've created an external content type based on OData. I imported created bdcm file to BCS store in central administration. So the ECT is scoped to the farm. I could create
an External List and the data from OData service was displayed. But I couldn't get the ECT crawlable. When I try to add a new content source in Search Service Application and select Line of Business Data it isn't possible to select External Data Source. I
tried to add IDEnumerator method and RootFinder property to the ECT in order to get it crawlable without any luck.
External Content Types based on MS SQL are crawlable fine.

Hi,
In order to use the ECT for search you have to manually edit it as it's not complete for use with search. The two most important ones to add are:
ShowInSearchUI
RootFinder
I experienced the same issue when creating an OData BCS model for my session at the SPC2012 conference and I think those were the two properties I was missing (in addition to cleaning up some other stuff).
Take a look at
MSDN for more information on BDC model properties, and take a look at Search Connector Framework Troubleshooting for SP2010 which shows some samples.
Let me know if you need more help and I can provide a copy of my OData model (which is against an SP2010 site)

Hello Community,
I have created an External Content Type in SP Designer 2013, and the connection and operations all seem to work fine, but the ECT List throws an access error, and when I check the BCS Service Application the ECT doesn't even appear in the list. Has
anyone else ever seen this kind of problem and if so please brovide guidance and examples for resolving it.

Hi Tom,
Have you created external content type from SharePoint designer 2013 successfully prevously?
And was it displayed in BCS service applicaiton previously?
Have you executed "External Content Type Operations" and saved it back successfully in SharPoint Designer like the following article?
Please check if it is related to the permission issue by using SharePoint Farm Administrator account to create this external content type.
If all above don't solve the issue, please check the ULS log for more information for troubleshooting when create the external content type.

External Content Typ: "Connection manager did not return valid connection."

Hi,
I created an external content typ in the sharepoint designer which takes my custom WCF Service as a data source. I sucessfully added all my required operations and created a new list based on the new content typ. At first I had a security issue which I got
resolved by editing my BDC configuration in the Central Administration. Now I face a new issue. When I open my external list the BDC Service gives me the following error message:
"Connection manager did not return valid connection."
Has someone a solution for this kind of message?
Thanks,

Group by collapsed not working for external content type

Hi,
I've got a list that displays data from external content type and I need it to be grouped by a column and have it collapsed by default.
The problem I have is that on a page by itself everything works fine. But when I add the list on a page with other web parts rendering the list as collapsed doesn't work as expected.
It will render the group headers correctly and everything is collapsed. But when I expand one of the groups ALL items are shown under that group, even the ones that belong to some other group. I then expand another group and it also shows ALL items. But when
I set the default to expanded each group header only has the items that belong to it, even if I collapse it and then expand again.
As I said, having the groups collapsed works fine if the listview is by itself on a web part page, but as soon as I add another web part (doesn't matter what type) it stops working.
Is this a bug or might there be something I'm doing wrong?

Hi,
As this issue is submitted via internal pipeline without external URL can be provided, we will keep focus on it to see if there any update.

External content type error: Business Data Connectivity object not found.

Hello
I have to change the external database (external system) for an external content type. The database view on the new database is exactly the same as on the old database.
After changing the external system of the external content type, this happens:
When I try to add a new item to the list, I get this error under the external data field:
"Business Data Connectivity object not found. Administrators, see the server log for more information."
Also, when I try to update the external data field, it is not possible because the buttons are grey.
When I add a new external data field to the same list, I can use the external content type. For some reason the current external data field doesn't update.
Any ideas?
Any help would be much appreciated!

Have you implemented both ‘Read List’ & ‘Read Item’ operations in your ECT?

Not able to crawl all items from External content type

Hello All,
"All the records in my external content source are not getting crawled, only 1/3 rd of the data are getting crawled."
Steps:
I created "External content type" using sharepoint designer which connects to a SQL Server database.
Have written a SQL View joining 2 tables, which return 9,00,000 rows when executed using the SQL Server management studio.
I used the default "Business Data Connectivity Service" and "Search Service Application" and made sure the necessary permissions are set.
Created a External Content source for the search service application and selected the "Business Data Connectivity Service" -> "Crawl selected External datasource" -> <my external datasource i created in sharepoint designer>
Issue
When i ran the full crawl for the first time it crawled "3,49,923" records in 01 hour and 07 seconds. And returned 1 error "Error crawling LOB Contents.(Error caused by exception: System.InvalidOperationException. There is an error in XML
document...)
Later i removed the below item from the index and started a full recrawl, this time it crawled "3,49,924" records 1 record extra from my previous crawl
and no errors were returned.
Please let me know what could be the issue. It doesn't look like the permission related issues as i am able to crawl the 1/3rd of my total data. Also i am able to search the crawled data. I also set the throtteling limit for the "Business data catalog"
to -maximum 10000000 -default 1000000 which is less than the data it has to crawl.
SRIRAM

Hi ,
I started the change suggested in the link shared by you, but got stuck at a point,
The field which i set as identifier in BCS earlier is not having unique values. Total rows returned by the sql view is 899000, but the unique values present in the column that is set as identifier is
3,49,923, which is equal to the number of rows crawled. - Is this the reason why it didnt crawl all records?
The table that is used in the sql view has composite key, - Is it possible to have multiple identifier in BCS as well?
Is it possible to make BCS to ignore the identifier? i mean creating BCS without an identifier column?
Please let me know your suggestions on this.
Thanks,
SRIRAM
Yes, BCS needs a UID. This is so it can figure out changes over time to a single record. Otherwise all changes to a row could be a potential new row without BCS knowing any better.
Yes, or just have it run off the composite key instead of the field you're using now.
Nope, BCS needs a UID field like in answer 1 :)
Good luck!

How to read the content from a External Content Type with out creating External List in Sharepoint 2013?

Hi,
I have a requirement to read the External Content Type and storing the Data in a Session Variable. The Reading of the content from External Content Type with out creating a External List.
Please help I am trying to find the solution, but unable to do that.
Thanks,
Pradeep

Hi,
Firstly an external content type designed to work with SharePoint list and there is no way to read apart from this.
If you are looking the solution out of the " Business Connectivity" then find that data source has been exposed through WCF and Web Service ?
So you can use REST API and CSOM to consume those data in SharePoint.
You can also leverage the ADO.NET option if the datasources based on MS technologies.

Unable to edit ReadItem and ReadList operations on one specific external content type

I'm experiencing a strange behavior. Here is the scenario:
- In Sharepoint Designer I create external content type A that uses external system X
- I define ReadItem and ReadList operations for this external content type
- I then create external content B that uses the exact same external system X and define ReadItem and ReadList operations for this external content type
- I then go back to external content type A, select ReadList and click Edit This Operation
- I get a message : "This operation cannot be matched with any objects in your data source. There may be an error in the operation definition in Business Data Connectivity Metadata Store or the data source schema has changed since the operation
was created"
- I tried to edit ReadList operation of external content type B and it works with no problems.
- so I delete the ReadItem and ReadList operations for external content type A, refresh external system X, and then recreate the ReadItem and ReadList operations for external content type A.
- When I try to edit the ReadList (or ReadItem) operation I get the same error message and I'm not able to edit this operation.
This used to work a week or so ago, meaning that I was able to edit the ReadItem and ReadList operations for both external content types. Now, the operations cannot be edited anymore for external content type A but can be edited with no problems for
external content type B. For content type A, if I want to make any changes I have to delete the ReadItem and ReadList operations and recreate them. Does anybody have any idea as to what the problem might be? These two external content types
use the same external system which is a table of employees and project they worked on. The only difference is that external content type A has a filter by employee ID defined and external content type B has a filter by project ID defined.
thanks,

Hi bbatl,
I did a test as the followigs:
Open SQL Management Studio, create a table containing a filed called “employee ID” and a filed called “project ID”.
Add some data into the table.
Open my site with SharePoint Designer 2010, create a new external content type called TestA.
Connect the external content type TestA to the table that I created in step 1.
Create Read Item and Read List operations in the content type. When creating Read List operation, add a filter based on “employee ID”.
Click Save.
Create another external content type called TestB
Connect the external content type TestB to the table which was created in step 1.
Create Read Item and Read List operations in the content type. When creating Read List operation, add a filter based on “project ID”.
Click Save.
Then I went back to edit the Read List operation of external content type TestA via clicking Read List operation under External Content Type operations->Edit Operation.
No error displayed.
So, I could not reproduce this issue.
Whether you got the error when you clicked “Edit Operation” in SharePoint Designer. Please provide a screenshot about this issue.
Please check whether someone has changed the table special for the column “employee ID”.
And whether you have created an external list using the problematic external content type. If yes, please check whether it could work well.

Wendy
