Hi there, zfayad. 

Thank you for taking the time to clarify your concern regarding the changing of transaction numbers for invoices, credit memos, or refunds. The system generates these numbers in sequences and depends on the previous number to maintain consistency and avoid duplication. 

However, I understand you want the transaction numbers to match other transactions. Therefore, as a workaround, one possible solution is to change the transaction number to match the previous transaction manually.

To do this, you can manually edit the transaction number field and enter the desired number. Remember that this may cause some discrepancies in the system, and it's important to double-check your records to ensure accuracy.
