## Summary of Purchase revisions

## Key Features

* **Revision triggers:** Updating the Pricing reference field on a purchase requisition line initiates revisions for both standard and blanket purchase requests, updating line and total amounts and triggering approval reassessment.
* **Revision scope:** Quantity remains unchanged during pricing revisions; budget changes apply only to blanket purchase requests.
* **Manual revisions:** Allowed on purchase requisitions without a linked purchase order if not in a closed state, without creating new revision requests.
* **Purchase order revisions:**
  * Shopper-initiated revisions create a revision request and revised purchase requisition without needing procurement specialist confirmation.
  * Procurement specialists can initiate revisions directly via the Sourcing and Purchasing Automation module.
  * Blanket purchase order revisions allow changes to quantity and budget, with back-calculation ensuring consistency and preventing reductions below released amounts.
* **Status and approval updates:** Revisions update purchase requisition and order states to Pending Revision, triggering delegation of authority reassessment.
* **Update process:** When revisions are approved, users can update existing purchase orders with revised data, closing the revision request.
* **Restrictions:** Revisions are blocked on lines fully received and can only be made for amounts exceeding received quantities.
* **Rejection impact:** Rejected revisions revert purchase requisitions and orders to prior states, with nuanced behavior for single and multiple line revisions.
* **Cost allocation management:** Original cost allocations carry over to revisions; fund changes create new cost allocations reflecting increases or decreases tied to the primary cost center.
* **Milestone handling:** Milestones copy from the original to revised requisitions; additional milestones can be added during revision, and original milestones close upon purchase order update.

## Practical Implications for ServiceNow Customers

With purchase revisions, you can flexibly manage changes to your procurement requests and orders while ensuring compliance through automated approval reassessments. This capability supports dynamic budgeting and quantity adjustments without disrupting existing supplier or business owner relationships. The detailed handling of cost allocations and milestones preserves financial and project tracking accuracy throughout the revision lifecycle. Understanding the revision states, restrictions on fully received lines, and the impact of rejection helps you maintain procurement integrity and control.  
Revisions for the quantity of the product, budget, or delivery location can be made to
orders placed from ShoppingHub.
The shopper can revise an order from ShoppingHub or the procurement specialist can submit revision from the Sourcing and Purchasing Automation module.  
When a shopper updates the Pricing reference field on the purchase requisition line, a revision is triggered for both standard and blanket purchase requests.

* For standard purchase requests, the quantity is left as-is. The total line amount is updated, which in turn updates the total amount of the purchase request and triggers reassessment of approvals, if applicable. Budget, even if populated, is not considered as a revision attribute.
* For blanket purchase requests, the quantity is left as-is. The total line amount is updated, which in turn updates the total amount of the purchase request and triggers reassessment of approvals, if applicable. In this scenario, the revision line captures the change in the pricing reference as well as the budget.
{#purchase-revisions__ul_v4j_2y4_snb}

When a purchase order is created, the pricing reference on the purchase requisition line
cannot be revised.

## Revisions with no purchase order {#purchase-revisions__section_oxg_kds_hlb}

If no purchase order is created, and state of the purchase requisition is not
Closed Rejected, Closed Complete, or
Closed Canceled, you can manually revise the purchase requisition.
In this case, neither a revision request nor a new purchase requisition is created. You can
view the updates in the Revision Lines related list of the purchase requisition line.

The addition of a new purchase requisition or purchase order line is restricted to the same
supplier and business owner for a revision process.

## Purchase order revisions {#purchase-revisions__section_nmc_chr_flb}

* Shopper-initiated purchase order revision:
  * When the status of a purchase order is not Closed Complete or Closed Canceled, a shopper can revise the lines from ShoppingHub. A revision request is created and assigned to the procurement specialist, and the state is updated to Closed Complete. A procurement specialist does not have to confirm the revision request prior to creation of the revised purchase requisition.
  * A new purchase requisition of type Revision is created and the revision request is attached to the revised purchase requisition.
  {#purchase-revisions__ul_db2_lml_mnb}
* Procurement specialist-initiated purchase order revision:
  * To initiate a revision of the purchase order, select Revise in the Sourcing and Purchasing Automation module.
  * On confirmation of the revision, a new purchase requisition of type Revision is created and the revision request is attached to the revised purchase requisition.
  {#purchase-revisions__ul_twd_sml_mnb}
* Shopper-initiated blanket purchase order revision:
  * When the status of a blanket purchase order is not Closed Released, a shopper can initiate a revision from ShoppingHub. Only the quantity and budget can be revised on a blanket purchase order.
  * When a budget revision is made, the quantity and total line amount of the corresponding blanket line is calculated to the nearest value using the negotiated unit cost of the supplier product. Revisions cannot be below the current released amount against the blanket purchase order. Revising either quantity or budget results in the other being back-calculated accordingly.
  * On confirmation of the revision, a new purchase requisition of type Revision is created and the revision request is attached to the revised purchase requisition.
  {#purchase-revisions__ul_ddg_vml_mnb}

{#purchase-revisions__ul_byk_kml_mnb}

For both the shopper-initiated and procurement specialist-initiated purchase order and
blanket purchase order revisions, the status of the purchase requisition is updated to
Pending Revision and delegation of authority is reassessed.

The state of the purchase order and the purchase order lines that were revised are updated
to Pending Revision. The state of the purchase order lines which are
not revised does not change.

When the state of the purchase requisition is Final Review and the
purchase requisition is of the type Revision, you can select
Update Purchase Order to update the existing purchase order and
purchase order lines with the revised information.

State of the purchase requisition is then updated to Closed Complete.  
Note:  
Revision requests must be in a closed state for a purchase order to be created. For more
information on purchase orders, see [Purchase order](https://www.servicenow.com/docs/0e9PRP9rk8Me33TxOFA3zw "A purchase order is a binding contract between a buyer and a supplier that authorizes a purchasing transaction. It contains the descriptions, quantities, prices, applicable discounts, payment terms, delivery dates, and other associated terms and conditions with the supplier.").

Revisions are not allowed in ShoppingHub for lines that have been fully received.
Revisions can only be triggered for an amount that exceeds the received amount.

## Impact of rejecting an increase in funds revision {#purchase-revisions__section_lwf_nnk_ynb}

If a purchase requisition or purchase order is revised, and the re-approval is rejected,
the behavior is as follows:

* If a purchase order doesn't exist, the purchase requisition is reverted to the pre-revision state and value, for both single and multiple lines.
* If a purchase order exists, and the good or service has either been partially delivered or not delivered at all:
  * For a single line, the original purchase order remains as-is. The purchase order reverts to its state prior to revision. The resulting purchase requisition of type Revision will be in the Closed Rejected state, with no option to update the purchase order.
  * For multiple lines, if every line within the revision purchase requisition is rejected, the impact is the same as above.
  * For multiple lines, if some of the lines within the revision purchase requisition are rejected, only those rejected lines revert to their state prior to revision, upon updating the purchase order.

## Purchase revision impact on cost allocations and milestones {#purchase-revisions__section_ntt_qrr_hlb}

Cost allocation behavior
:
    * Cost allocations from the original purchase requisition are updated in the revised purchase requisition.
    * If an increase or decrease in funds happens, a new cost allocation is created for the primary cost center (cost center of the business owner on the purchase requisition) on the revised purchase requisition. This amount reflects either
      as an increase (positive amount) or decrease (negative amount) in
      funds.

    * Once the purchase order is updated, the revised purchase order contains separate entries for the primary cost center, that is, the one from the original purchase requisition and another as a result of the revision, along with any additional user-defined allocations from the original purchase requisition.
    * Cost allocations cannot be updated after the creation of a purchase order.
    {#purchase-revisions__ul_cqj_trr_hlb}

    For more details on cost allocations, see [Cost allocations](https://www.servicenow.com/docs/ItBh2YlupWx9xcRw732mzw "Cost allocation defines how to allocate the payment for a particular purchase line. Costs can be allocated towards a cost center, employee credit, or payroll payments.").

Milestone behavior
:
    * Milestone details are copied from the original purchase requisition to the revised purchase requisition.
    * User can create any additional milestones, as needed, on completion of the revision.
    * Once the purchase order is updated, the original milestone on the purchase order is updated to the Closed Canceled state, as a copy is already created during the revision process.
    {#purchase-revisions__ul_c52_lsr_hlb}

    For more details on milestones, see [Milestones](https://www.servicenow.com/docs/qCJ0NyjakeclU7~cgmrOhw "Milestones represent an acknowledgment that a certain deliverable is achieved for a service. You can create a milestone against the purchase line and purchase order line for a service product type, when the acknowledgment type is set to Milestones.").
