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?

Date in External Content Type 1 hour later than MSSQL date

I have an MSSQL table with a date column. I have created an external content type which pulls data from from this MSSQL table. But when the content type is shown in a list in Sharepoint 2010 site, the date is 1 hour later than the date from the MSSQL table?
This is my MSSQL dates:
This is my SP 2010 dates:

I'm going to guess that this has to do with server time and sharepoint time. SharePoint time can be found under regional settings. Check to see that it's consistent with the time zone of your other server.

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

Meaning of "Map To Identifier " while creating an External Content Type

In SharePoint 2010 Desginer, I created an External Content Type that retrieves data from a VIEW in SQL Server. In the wizard, I see "Map To Identifier." What is the purpose of that. I want to understand the meaning of Map To Identifier? Thank you.
Mayank

Hi Mayank,
When we create database-based external content type, we could map the data source element to an identifier of the related external content type as input to the association.
In the Data Source Elements pane on the left side, select the data source element in the list. In the
Properties pane on the right side, select the Map to Identifier check box. In the
Identifier list, select the appropriate identifier.
The database object name is referred to as its identifier. An object identifier is created when the object is defined. The identifier is then used to reference the object.
http://msdn.microsoft.com/en-IN/library/ms175874.aspx
We map the field of the external content type to the identifier of the external content type.

ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified in windows server 2008 r2

ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified in windows server 2008 r2.I made a application in asp.net c#.I am using ODBC connection.When I deployed my application in windows server2008 r2.There

</connectionStrings>
Guide me What I do?

Did you add a System DSN or a User DSN? If you added a User DSN from your own login, the asp.net application will not be able to use it unless its application Pool in IIS is configured to run under the same credentials that you used for creating
the DSN. It's better if you add a System DSN.
Also, be careful to ensure that you are using a 64 bit DSN, unless you configure the application to run in 32 bits. If the 64 bit application attempts to use the 32 bit driver you get the same error message "Data source name not found and no default
driver specified". See this KB article:

FTPOpen Data Connection: Could not establish connection

I need to transfer data files from a local directory to a remote system via FTP.
I can open an FTP connection, login and list existing files at the remote location. I even tried to rename files at the remote location, it works.
Trying to sen files to the remote location using the FTPPutFile.vi causes an error "FTPOpen Data Connection: Could not establish connection".
Any idea, what causes that error?
Thank you in advance,
Andreas Langer

That's very peculiar that this should be happening, as it obviously sounds as though you have already established a connection. Have you tried running any example VIs? This is usually where I start to debug a problem. It shows me whether my code is wrong or something else (which is hopefully the issue).
I found a good example for you on NI's website which makes a call to both "Get File" and "Put File". It ran successfully for me. You may want to see if it gives you the same errors.
It's currently configured for an FTP server which I use, so you'll want to change its connection, but that's available through the front panel. Let me know how it works for you.

Find Object.vi function of 3D picture control - when object not found

I am using Labview 8.2, and this post is regarding the 3D Picture Control.
I am wanting to make use of the "Find Object" VI to either return a reference to a named object, or otherwise determine that it does not exist yet. However, if I call it with the name of an object that doesn't exist yet (i.e. just any random string), it returns an error message that arises from the attempt to release a queue (the reference to which gets lost when crossing a zero-iteration For Loop's tunnels), instead of an error message that says "Object not found" which I would find much more useful. With a simple modification of the "Find Object.vi" function, this behaviour can be changed, by replacing the For Loop's tunnels with shift registers.
The problem with the current function is that the error is not an intentionally thrown error, rather just the result of the queue's refnum being set to the default 0 as it "exits" the For Loop, since in the situation that an object is not found, the code passes a 0 to the N terminal.
The attached images show the problematic code and the simple modification

pauldavey,
I agree with you - the current way of handling the case of an object not being found does not appear to be ideal.
This was reported to R&D (# 43D8GSVQ) for further investigation.

Data Source - Alias Not Found in SDK Sample Application VIDS

Hi,
I am trying to run SDK sample application VIDS.
In the function, BindDataToForm, I am getting error at line:
oColumn = oColumns.Item("CardCode")
oColumn.DataBind.SetBound(True, "@VIDS", "U_CARDCODE")
The error is: Data Source - Alias Not Found
I have checked that the user tables and the fields in the user tables are correct.
What can be the issue?
Thanks.

Hi Rajesh,
Works just fine for me.
Double check that you've created the userfields. You must press the button create user fields before attempting to use the sample.

"Access denied by Business Data Connectivity" on trying to connect to SQL server for creating external content type

I was trying to create external client type but whenever I try to connect to Database server it is showing me error"Access denied by Business Data Connectivity". I have given the Secure Store Target Application ID coorectly and it is setup coorectly.
In BDC service application I have given myself all the permissions( edit,execute,Selectable in clients,Set Permissions) through set metadata store permission option in it.
Please suggest what other reason can be there for the error.
Thanks and Regards
Gaurav

Hi Gaurav,
If you have given your account all permissions through setting metadata store permission, the issue should be resolved.
For a better trouble shooting , I suggest you do as the followings:
1. Assign administrators to a Business Data Connectivity service application
Here is a detailed article for your reference:
http://technet.microsoft.com/en-us/library/ff973113.aspx
2. You can try to recreate a Business Data Connectivity service application to test whether it works.

Error while crawling LOB contents. ( Access denied by Business Data Connectivity. )

Hi,
When I execute Incremental or Full Crawl I get 17000 error and only 1 success.
The error is:
Error while crawling LOB contents. ( Access denied by Business Data Connectivity. )
I went to Central Admin > Security > Specify Web application Policy > Search for the service account for crawl and it's "svc_SPSearch"
I went to Central Admin > Application Management > Manage Service Application > BDC Service > I select all the affected external sources > then Set Object Permission in ribbon > Added "svc_SPSearch" with execute rights > then
kick incremental crawl...
After this I still get 17000 error, 1 success.. Still an error.
I am not sure how the crawler's trust to FAST infrastructure works.
Your response is appreciated. Thanks!

I have the same issue.
I have Configured the BDC Service application using SQL external content. The connection was successful and I am able to see the external content in the List "BDC Demo" . But when I search in the BDC Demo site it gives nothing.
So I checked in the crawl logs and identified that it shows " 1 " under error. to further drill down the issue , I went to click on "1" and see the error message : Error while crawling LOB contents SharePoint 2013 .
I have created an external DB named BCSDemo_DB for which I have granted my search Service account read& write permission.
I have added the same account under administrators for both secure store and BCS service applications.
I have done index reset , done a full crawl but the error still occurs.
Can someone please advise if I am missing something.
Regards

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 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,
Eric
