Hello,

Yes, this is achievable in Odoo, but it depends on how the journal entry sequence is configured.

The "Sequence Prefix" field you mentioned is more of a display hint and does not always control the actual numbering unless the journal is linked to its own dedicated sequence.

If all your entries are showing BNK1, it likely means:

• Multiple bank journals are using the same sequence, or
• The sequence linked to the journals still has BNK1 as its prefix.

You may want to check:

• The sequence assigned to each bank journal
• Whether each journal has its own unique sequence with the correct prefix (ABC1, XYZ1, etc.)

If needed, you can create separate sequences per journal and assign them accordingly.

Hope this works for you! Feel free to reach out for further discussion.
