Is there an easy way to delete a large number of business partners? I know that you can go into each record to remove, but we have about 500 to delete.
You might want to check into an Addon from CRG (Corporate rennaisance) - They may allow you to delete a large group or perhaps to merge.delete all these bad accounts into one single account.
I would most certainly recommend using an add-on, if at all - when you delete Business Partners within the SAP program, they check to make sure there are no existing invoices, sales orders, etc. linked to that business partner before it deletes. The add-on (or whatever method you use) should have this same check built-in.
