Reusing Nota Fiscal Numbers (BR) 
In the Brazil localization, you can reuse the nota fiscal (NF) numbers of canceled documents. NF numbers of the following documents or sequences, however, are not available for reuse:
External sequence
Locked sequences
Sequences that are assigned to another branch if you have enabled multiple branches for your company
Note
Even if a canceled document has been archived, you can still reuse its NF number.
If a document occupies the last used number of a NF sequence and you cancel the document after activating the function of reusing NF numbers, this document no longer occupies the NF number. As a result, the next document added to this sequence automatically reuses the NF number; meanwhile, the number does not appear in the list of reusable NF numbers for manual selection.
Special Case: Cancellation of a Document with Last Used Number of a NF Sequence
If you reuse the NF number of a canceled document but change the NF model for the document after its creation, the new document still uses the default model defined for the NF sequence in the Sequence – <Document> window. Nevertheless, you can always update the model of the new document if you need to.
The following table gives an example of the seemingly inconsistent reuse of NF numbers:
Sequence / Document |
Model |
|---|---|
Sequence NFe |
Modelo 1 |
Updated canceled document A using a NF number from sequence NFe |
Modelo 2 |
New document B that reuses the NF number of document A |
Modelo 1 |
