I am a Sharepoint site admin without any development tools, I'm solely battling on with the Sharepoint web front end. What I would like to do is to create list items and generate a unique reference for each which can be shown when the line is edited or when sent as an RSS feed item. Presently I have a calculated field which consists of 3 concatanated fields, [dept] + [ID] + [change type].

The problem I have is that ID disappears when the item is edited or displayed as an RSS item ? I can only think that this is not a stored value but one calculated as the record is displayed ?

  • Should mention that I'm using SP 2007.

It is related to this question I think: Calculation field randomly forgets ID or this one Calculated Hyperlink Column - Lost ID-Field Value Upon Editing

ID is not supported in calculated columns and always disappear. I mean when you open list settings, check cal. column settings or change something in formula and hit OK, will be visible (for a while), but later when you add new item, new calculated value field will be blank again.
