Importing updated spreadsheet to an existing module

I have exported a module to Excel (.csv) and have updated the spreadsheet. I tried importing the updated spreadsheet to the existing module and have run into a problem. The change bar turned red, but the updated text were not imported. The preview part of the import screen shows the changes, but the change doesn't appear in the module. Have anyone experienced this before? Any advice as to what I should do?

I think you will find that you have imported the new data, it has generated new attributes. When you do a re-import from spreadsheet donot forget to mark the main column as "Object Text" or it will duplicate within a new column.
Other points are:
An empty column in the spreadsheet means on import, do nothing it does not delete the contaents within DOORS.
Only import the columns you want to update and a "key" column, best to use id which is called within DOORS "Object identifier", you need to use the sytem names.

Hope this helps
