📘 Overview

Customers often ask whether an existing Purchase Order (PO) can be amended, approved, and then combined with another PO. This article explains when PO amendments are supported in Microix and clarifies the intended use of the Combine (Consolidate) process.


🛠️ Amending Purchase Orders

Amendments are typically handled through Encumbrance Modifications, which are available only to customers who encumber their purchase orders in MIP Accounting.

Example: If you purchase a certain number of laptops from a vendor and encumber the purchase order, you would use the encumbrance modification process to amend the existing purchase order. The encumbrance modification is subject to an approval process, and the routing must be defined in the workflow.

If your process involves holding the PO in Microix, matching it to an invoice, and then sending it to MIP for payment, amendments are handled differently. In this scenario, use the Re-route button to return the document to the requester or procurement level for modification.

The re-route process requires the document to be approved again from the level to which it was returned and onward. Re-route can only be used if the original purchase order has not yet entered the payment or partial payment process.


📌 Key Takeaways

  • You cannot submit a new PO, approve it, and then combine it with an existing approved PO.

  • Existing POs must be amended using one of the following methods:

    • Encumbrance Modifications (for MIP-encumbered customers), or

    • Re-route, provided the PO has not started the payment or partial payment process.

  • Combine (Consolidate) is used only to consolidate multiple purchase requests into a single PO and is not an amendment tool.
