Unable to save changes in Datasheet View

Question

We have a custom list that we are trying to edit in Datasheet view and are getting the following error when the next row is clicked:

Another user has changed the structure of this list. All your pending changes to this list will be discarded. To retrieve the latest copy of the list, click Refresh.

Obviously, clicking Refresh causes all changes to be discarded. Items can be entered by using the New Item form without issue. I have also verified that there are no calculated columns in the view and that the values we are trying to insert contain no commas. I have also verified that the choice columns do contain the values we are attempting to use.

Here is the structure of this list:

Here is the structure of the view:

Are we missing something obvious? Any suggestions would be greatly appreciated, thanks.

SharePoint error – “Another user has changed the structure of this list” July 15, 2009 Recently while working on a recent SharePoint project, we ran into a problem when multiple users were editing a list item in the Datasheet view. We started seeing the following error below:

After searching online I found some solutions that recommended removing check-box columns from the view, however this did not work for me. I eventually opened up a case with Microsoft Services Premier Support (thanks Josh!) and we finally tracked this down to another column that contained a comma in the hyperlink URL (to a pdf drawing in another library):

Renamed the pdf drawing to not include the comma, added the updated hyperlink to the list item and no more error when editing other fields in a datasheet! This was pre SP2, so I don’t know if the issue still exists after installing SP2 or any cumulative rollups.

Answer 2

I've seen this before where a title column, for example, is required but hidden in the datasheet view. In your case it looks like both of the required columns are exposed on the datasheet view, so I'm assuming you are entering them.

One thing you might consider is deselecting the columns one at a time from the datasheet view until it works. This will help you determine which column is causing the error and maybe give you a better idea what is going on.

Answer 3

I had the same issue. In my case it was a combination of 2 things...each which caused the issue. 1) A COMMA in the URL in a hyperlink field. Took out that URL (moved it to a non hyperlink field) and I was back in business. 2) A column that had column validation turned on, but that did NOT have that column in the datasheet view. Once I put the column in the datasheet view AND choose an appropriate value, all worked as intended. That was a tough one to crack!

Answer 4

For us it was some columns are indexed twice. So we created index for: Column A, Column B, Column A + B

By removing the third index we solved this issue.

Pretty hard to understand why Ms even allow the combination in this case.
