Currency and number column error with office 2007 document formats in SharePoint 2010 library

Hi there,



The following error occurred within a SharePoint 2010 document library:

As I tried to test out the new SharePoint 2010 environment I changed the metadata from a few documents within a document library. I noticed that the data from the currency und number field was incorrect from a few documents. The numbers looked like that the decimal separator were ignored. For an example: 123.456,78 was saved as 12.345.678.

At first I thought it could be a language incompabilty but if that would be the case: Why would there be other documents which show the correct number?


I created another document library to recreate this error. And there I noticed the real reason: Every time I changed these fields from a document which was saved in the office 2007 format the error occurred. The metadata from the documents in the office 2003 format were correct.


Has anyone a similar problem or got an idea how to solve this problem?

Unable to save Office 2007 document to SharePoint My Site Personal Documents document library


...also when Office documents are saved to document library they open as Read-only and cannot be saved back to the same document library.

This only happens in my production SharePoint 2007 environment from client XP and IE7 machine.  It does not happen in developement environment (which mirrors production) from client XP/IE7 machines.

Save works fine to SharePoint document libraries from client Win 7 and IE8 machines in both production and development environments.

This only happens when attempting to save to a My Site Personal Documents document library.  Any other document library this behavior does not exist from XP or Win 7 machine.

What settings controls ones ability to save to a personal My site document library.  What setting could be different between prod and dev installations?  It only happens

Newly promoted column in infopath not displaying value in sharepoint 2007 form library


Hi All,

I have a form library, which is allready having nearly 200 forms. Now i need to promote some more infopath 2007 form fields to sharepoint 2007 list column. But after promoting and re-publishing the infopath template, newly promoted columns does not show any value. Please suggest me how to fix this problem?

Work around :- If i just open a form and save it back, newly promoted field(Sharepoint library column) is displaying correct value. But this would be a tedious task if it has to be done for nearly 200 forms.


Thanks - Rajkumar Rurhi

Unable to open pdf from document library MOSS 2007


When I click on a pdf document uploaded in a document library it comes up with a blank page. 

I guess it's trying to open pdf on the browser. I turned off "Display PDF in browser " option in Adobe Preferences, but it doesn't help, same issue.

I tried other browsers too, it's the same issue.

I am able to open all other pdf files local to my machine fine.

I am using IE 8 on my machine (Windows 7) and the Sharepoint server is MOSS 2007.



Unable to export/copy documents out of SharePoint 2007 libraries

Hi, A client had an issue a few months ago where their MOSS 2007 home site collection had to be restored after a major crash, it now works but they have loads of issues with the restored site(no need to go into) now I am trying to migrate the Data (files and folders only, no security or metadata) to a SharePoint 2010 installation, the problem is that I am unable to get any of the files out of SharePoint. I decided against an upgrade or any form of site migration as I might only be taking the problems with me. i am just trying to copy the files using the "Library - Actions - Open with Windows Explorer". The Explorer view window opens but if i select a file and move it into a folder on the server nothing happens, If I select a folder with files and folders in it then only the root folder is copied over but it is empty.  i don't want to repair any of the issues with the old site as it's only wasting time, can anybody think of a way to get all of the data out of Sharepoint 2007, without taking any of the lists or libraries or any other Sharepoint settings. I only need to keep the folder structure and files within them as i don't need any metadata and am recreating the security again seperately on the new SharePoint setup. Anybody have any ideas or know of free/trial products that i

SharePoint 2007 to Access 2007 - Issues grouping by "Person or Group" field type/column

We are on SharePoint 2007 and using Access 2007.  The SharePoint list contains a column called Assigned Person, column type: Person or Group, single selection, displaying only the name 1) When we Open with Access and Export a copy of the data, then create a report from that table, we do not have the option to group on Assigned Person.  2) When we Open with Access and Link to data on the SharePoint site, then create a report from that list, when we group by Assigned Person... The same person has 2 groups - there are is no other grouping or sorts on the list, and i can't locate a correlation to another field to show why they would have to collections for the same person The Person or Group column sorts "from smallest to largest" as though it is a number field. The list is a task/activity tracking system we created custom for our needs.  We want to pull a weekly report, grouped by Assigned Person, but cannot get access to work.  We do not want to resort to anything more complex, as it takes a much longer process to have reports pulled by Chrystal or one of those types of applications.  And we cannot change out the field for something like a Choice column as the list already has a very large amount of content.  Can anyone assist? Is there a setting hiding somewhere that is causing the problem?

Sharepoint 2007 - 80GB Documents in 1 document library

Hi, My customer wants 'customer docs' in SharePoint. It is now stored on several disks and wants to move it to SharePoint 2007(!). It needs to go into a folder structure.....I'm now investigating the information that needs to move to SharePoint and it turns out a quick scan resulted in 210.000 documents with a total volume of 80GB. Off course this is raw data and thus containing archives, zips, access databases and a lost movie and the like (just like any normal network drive :-)). When I look at the limits and best practices: no folder should contain more then 2.000 items (OK) no doc lib should contain more then 2.000.000 items (more then OK) no file should be larger then 2GB (OK - we set it to a max of 150MB) It is all fine but my concern is the shear size of the total load. Let's say they don't migrate 80GB but 30-50GB. My Question: can a single MOSS 2007 document library hold this kind of documents and total size? What does this mean for overall performance, backup, search indexing, crawling etc etc?  Thnx for any tips!

Migrate/Move Document Library from Sharepoint 2007 to Sharepoint 2010

Hi, I have a customer that is setting up a new SPS 2010 environment. They have a Sharepint 2007 environment with one document library containing only PDF files. They will not need any metadata on these documents, but would like it to be moved to the new SPS 2010 environment only to be used for history and free text search. Is there an easy way to accomplish this?   Regards Christian GrannesChristianLLoyd

Uploading Excel 2007 table into WSS 3.0 - How does SharePoint decide the column that is used to edit

Hi, In Excel 2007, there's an option to upload (export) an Excel table into SharePoint.  The range of cells have to be identified as a table.  In the Table ribbon, there's an Export button.  When I upload the Excel 2007 table, SharePoint (WSS 3.0) decides which column in the table will be linked to the properties dialog box for each line in the table.  It seems to be a sporadic decision on the part of SharePoint. Does anyone know how WSS 3.0 decides which column will be linked to properties?  And, is there any way to control this when uploading the file? Thanks!Thanks! Patti N.
