I accidentally uploaded 2,000 Business Partners through the DTW with just the Card Code and no other data. My initial thought was I would have to delete them 1 by 1 as the DTW is great for getting data in but not getting it out! I then found this solution I want to share:
Use the Boyum B1 Usability Pack master data manager to list the offending BPs and delete them. I’d strongly recommend a backup of the DB first
Its under Admin / Addons / B1 Usability Pack / Module config / Master data manager / business partner master data manager
In the condition box put the following: where cardname is null
Click find
Assuming its found the ones you want goto the special tab and click delete selected BPs
