How to add a new DUNS number to my enterprise

How would I add a new DUNS number to my enterprise in TN
I can easily add DUNS number for my partners(the add External ID button is enabled). Buyt when I select my enterprise, it is disabled. (I can edit existing external IDs, but not add one.)

What version of TN are you using?

Try using this TN Service wm.tn.dictionary:addIDType…which will let you add multiple External ID’s…

HTH.
