Hello All,
Im trying get connect the sqlserver tablt to Sharepoint List using BCS services + Sharepoint Designer.
i have created the external content type using SPD, creating all permission to table, operation properties, parameter, filter parameter every thing is fine.
then here i have to SAVE the external content type, im getting error: External Content Type Failed to SAVE
detailed Error:
An unexcepted internal error occured in the Business Data Connectivity Sahred Service: Access to the temp directory is denied. identity 'NTAUTHORITY\NETWORK SERVICE' under which xmlserializer is running does not have sufficient permissions to access the
temp directory. CodeDom will use the user account to process is using to do the compilation, so if the user doesnot have access to system temp directory, you will not to be able to compile. Use Path.GetTempPath() API to find out the temp directory location
Before this i created sample external content type which is working correctly. Any suggestion regarding this..
Advance thanks..

Hi,
I understand that when you save the external content type, there is an error.I have seen similar errors, you can try the steps below:
Open C::\Windows\Temp.
Right click on Temp folder and choose Properties>Security.
Add the Network Service with Full Control permisison.

Get "An Error occurred while retrieving data From ProjectWebApp.." when searching content on an External Content Type

I have set-up an ECT in SPD2013 on SP2013. It is a SQL Data source called ProjectWebApp. I have BCS/SSS set-up. I can create an ECT OK in SPD. I can add the ECT to a custom list.
The problem is when I add a new item in the list the following error message appears in red
An error occurred while retrieving data from ProjectWebApp. Administrators, see the server log for more information
I cannot filter or return any results. There is data in the DB.
Another test I do is to try and create a new App/List using the "External List" template. When
I select the ECT a red message appears "External Content Types are not available". which is odd since I can add an ECT to a list as mentioned above.
Any ideas?

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?

Creating a external content type for Read and Update data from two tables in sqlserver using sharepoint designer

Hi
how to create a external content type for Read and Update data from two tables in sqlserver using sharepoint designer 2010
i created a bcs service using centraladministration site
i have two tables in sqlserver
1)Employee
-empno
-firstname
-lastname
2)EmpDepartment
-empno
-deptno
-location
i want to just create a list to display employee details from two tables

adil

When I try to create an external content type based on a view (AdventureWorks2012.vSalesPerson) - I can display the data in an external list. When I attempt to edit it, I get an error:
External List fails when attached to a SQL view
Sorry, something went wrong
Failed to update a list item for this external list based on the Entity (External Content Type) 'SalesForce' in EntityNamespace 'http://xxxxxxxx'. Details: The query against the database caused an error.
I can edit the view in SQL Manager, so it seems strange that it fails.
Any advice would be greatly GREATLY appreciated.
Thanks,

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

Setting up an External Content Type

Is it possible to set up an External Content Type in SP Designer if the WCF service I'm using only has a method for creating an item in another system? I see that you must create a "Read Item" and "Read List" operation, and when I try
to do so, it doesn't allow me to see the "Finish" button, or it throws a bunch of various errors at the bottom.
I have a WCF service that was not specifically made for BCS. It's designed to simply submit a ticket to a help desk system, with no ability to read from that system. Using custom workflow in SharePoint, I'd like to trigger the WCF service and send a ticket
using data held in a SharePoint list. Any pointers appreciated!

Hi,
According to your post, my understanding is that you failed to set up an External Content Type in SharePoint Designer.
Please make sure you create external content type based on a WCF service
correctly.
For more information, you can refer to:

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!

Managing External Content Types - make it read only?

I have a simple SharePoint list with an External Data column. When I edit item where the corresponding data was removed from the External Content Type I get this error:
No exact match was found. Click the item(s) that did not resolve for more options. You can also use Select button to
choose External Data.
I assume this is by design and I cannot delete underlying data and keep the value in the list - is this correct?
So my question now - is it possible to keep that info in the external list but disable in a picker so new records cannot be created with that particular value? How do I do it?
Thanks,

I don't understand the question exactly, could you restate it. Sorry mate, I might just be braindead.
But, as far as the issue, it is by design. the column is a lookup columns which essentially ties to the external data. if that data is removed, the column on your simple list becomes invalid and any edits of the simple list item will require
it to be changed.
are you wanting to make the ECT read only? that's simple enough. you can pop open SPD and edit the ECT, then remove the C/E/D operations (create/update/delete). That will not, however make it read-only in any other systems that access that
external data, as I assume its not just SP or else it wouldn't be external

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.

Problems when trying to return information for External Content Types in Sharepoint 2013

This is my first post on the forum, until I tried on this problem but have not found anything.
When trying to return the information from the external content displays the following error:
Error retrieving data from mill. Administrators: query the server log for more information.
I do not know what else to do...

Hi,
According to your post, my understanding is that you got an error when tried to return the information from the external content.
Did the error occur when you created a new external content type or created a external list?
You can check the steps with the following articles about how to create a external content type.

http://wyldesharepoint.blogspot.in/2012/12/sharepoint-2013-setting-up-external.html
If the error occurred with the external list, you can check the steps with the following article.
http://community.bamboosolutions.com/blogs/sharepoint-2013/archive/2013/01/08/how-to-create-external-data-column-in-sharepoint-2013.aspx

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.

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.
