Hi ....Help! I have a problem with trying to generate a unique ID as a 'Project Number' in SharePoint. I have used the 'Calculated' column option in a list in sharepoint 2007 which uses the automatically generated ID column coupled with another column. The calculation i am using is '=[Building Code]&ID'. This works once but then on subsequent entries does not return the ID number. If you go back in and edit the list and resave it then automatically updates the entry (so this means manual intervention which does not make sense). Does anyone have any ideas on how to make this work or other ideas on how to generate a unique ID in sharepoint?
for example CG1234 (eg CG being the building code and 1234 being the ID field)
