The Reversal option creates a new batch with an opposite document type. For example if you Reverse an AP Voucher or AP Credit Memo it will create an AP Debit Memo with the same Transaction details. It does not delete or edit the source document in any way. This ensures an auditable record of the original transaction and its reversal.

The Duplication option allows duplication of any AP Invoice or Memo, AR Invoice or Memo or a GL Journal. This functionality is similar to the Dynamics SL Copy Special feature, but easier to use.

An extra option is provided to allow selection of only specific Documents within a Batch where required.  You can choose to only Reverse or Duplicate a tagged list of documents with a Batch.  This is extremely handy if you only need to correct or duplicate a small part of a large batch.

It s possible to select a Batch to be both Reversed and Duplicated.  The Both option is perfect when you need to correct an incorrect posting. Reverse the original incorrect Batch (or Document) and create a Duplicate batch that can be adjusted and corrected then released.
