Currently, the approval workflow for purchase order requisitions is configured in the ERP as follows:

Level 1: Approval is granted by an Accounting user, since they perform a validation of the accounting account before approving. Once approved, the request is sent to the next level.

Level 2: Approval is granted by the manager of the user who created the requisition. Once approved by the manager, the purchase order is generated.
