If your process has multiple approvers, when you enable the "Only 1 person needs to approve the transaction" option, your transaction will only need approval from 1 person. Here's how:
1. Go to Inventory -> select Settings menu -> select Approval Settings
2. Click on New approval setting button
3. Fill in the required fields and check on "Only 1 person needs to approve the transaction" option -> then click on Save button
4. Create a transaction that corresponds to the above approval process -> then click on "Save & Send Request" button
After pressing Save & Send Request, all approvers selected in the approval setting simultaneously receive approval request notifications via web and email.
5. One of them logs in and selects Approve / Reject, then the request changes to APPROVED / REJECTED status and the others can no longer approve this transaction.
Finally, the transaction creator will receive web and email notifications about the status of the transaction.
