In the M&A part of Thomson One Banker you can add “Acquiror Datastream Code” and “Target Datastream
Code” to your report. The result (for the Netherlands) is not worse or better that the SEDOLcode.
When you need data from Datatream it’s easier then SEDOL: no need to add UK and easier to explain to students. Unfortunately the excel add-in of Thomson doesn’t work with Datastream codes (only Mnemonics), so you still need the SEDOLs.
The item Datastream code isn’t in the list of definitions of the M&A module.
