Import and Automatic Creation
CSV imports of payables, receivables, and transactions automatically create categories by name when no match is found. If the category from the CSV doesn't exist in the workspace, it is created with the type inferred from the document's polarity.
Deletion
A category can only be deleted when it has no linked documents. To replace a category in use, reclassify the documents first or use Bulk classify in the listing.
