External content type using wcf service

Hi,
I have been asked to create a wcf service to expose sql data and populate them in a list using external content type.i have created the service but while creating the content type it gives me error.
"The server was unavle to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetails (either from ServiceBehaviorAttribute or from the <serverDebug> configuration behavior) on
th server in order................................"
Can anyone suggest some help.
Thanks..

Hi,
Based on your description, you encountered the error when you create the content type.
You can turn on IncludeExceptionDetails or use Service Trace Viewer Tool to see the details about the error.
There is a similar case:

External Content Type Using SQL

I’m trying to setup an external content type using just SharePoint designer.
I will need to be able to show other individual within the organization how to create these content types so getting it to work with just SharePoint designer is the goal.
No Programming involved please.
Abbreviated Steps I have taken
The account that we will use to connect to 2012 SQL server has been created and the correct permissions have been granted to the database.
The secure store service account has been created and setup
Go into SharePoint designer 2010 to create the external content type using
Impersonated Custom Identity and inputting in the username and password that was setup in SQL server and added to the secure store credentials for the secure store service. I receive error cannot login with the provided credentials.
I have searched the web trying to correct this issue and cannot find anything that will assist.
Everything either shows you to connect with windows identity (not an option) or breezes past this issue.

To connect as an impersonated custom identity you have to:
1. Be sure SQL login on SQL Server uses SQL authentication
(not Windows one!)
2. Create target application in Secure Store with:
a. Target app type - "Group"
b. Field types - Username and
Password
3. Don't forget to grant required permission to a new Traget Application.
Here is a good guide (look at steps 4-8):

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!

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.

Access issue relating to external content types

Hi,
I was recently given permissions in the Central Administration to edit external content types. However, when I open Sharepoint Designer and click on External Content types, I am unable to view the existing external content types that was created by another
site collection admin. The message I see is "There are no items to show in this view." I have the same permission level as this admin.
Any suggestion in regards to resolving this?
Thanks in advance!
Vidya

Hi Vidya,
For your issue, please confirm below check list:
Do you have permission to access the Business Data Connectivity Service? You can verify this by trying to open Business Data Connectivity Service management page of Central Administration in the Browser.
If you cannot open, please ask permission for yourself from the farm administrator. Reference:
Business Connectivity Services security overview.
Do you have Edit , Execute and Selectable In Clients permissions for the external content type you want to view? If not, please ask permissions for yourself. Reference:
Set Permissions to External Content Type using PowerShell.
If the issue persists, please go to Central Administration->Application Management ->Manage services on server, restart the Business Data Connectivity Service.
Reference:
External content types: There are no items to show in this view

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

Connect to MS Access using External Content Type

I am trying to establish connection to an Access 2013 DB from SharePoint 2013 Designer.
I am in External Content Type. My database is on local drive. When I click on Add Connection, I have the following choices,
.Net Type
SQL Server
WCF Service
Which one shall I choose for access. What would be the Database Server. The database is local.
Thanks
Mayank

Hi Mayank,
If you want to use ECT to display the data of the Access database, per my knowledge, you need to import the Access database table into SQL server, then use to ECT to connect to the SQL server table.
More information about importing an Access database table into SQL server, you can refer to the link:
