Once you have setup Transaction Authorisation, every time the transaction is executed, it will require an online approval by the person required to authorise before being posted.
Authorisations can be simple, or based on fulfilment of specified criteria, etc.
You can always View, Edit the transaction before you go ahead with approval.
You can either Reject or Authorize the Transaction based on criteria set by you. A specific report also can be generated for all the Approvals and Rejections with remarks/ reasons.
If you are not available on a laptop and need to approve a specific criteria based transaction, you can use the OTP facility to approve the transaction.
Following is a configuration to setup Mobile Notifications. You can also choose to which transactions you want the mobile approvals to be assigned.
