Process Step No.Process StepDetailsSOAP Service
1Create purchase requisition

In SAP S/4HANA Cloud, an employee or an MRP run (defined by a material planner) creates a purchase requisition for a material that has no source of supply.

Apps that can be used to create purchase requisitions manually are:

My Purchase Requisitions - New

Manage Purchase Requisitions - Professional

Create Purchase Requisitions - Advanced

For details check the unit Requisitioning (18J)

2Create request for quotation in SAP S/4HANA Cloud

In SAP S/4HANA Cloud, the purchaser responsible creates a request for quotation for one or several purchase requisitions, using the Manage Purchase Requisitions app. From the request for quotation, the purchaser can display all follow-on documents that are created in SAP S/4HANA Cloud.

Apps that can be used to create requests for quotation manually include:

Manage RFQs

For details check the unit Request for Price (1XF)

3Route request for quotation to SAP Ariba Sourcing

The request for quotation is transferred from SAP S/4HANA Cloud to SAP Ariba Sourcing using the Managed Gateway for Spend&Network. Notes that exist at the item level, as well as detailed description at the header level, are transferred to SAP Ariba Sourcing. Attachments that exist at the header or at the item level of the request for quotation are also transferred.


Information that is entered in the Detailed Description section of the RFQ is later displayed as the Sourcing Project Description in SAP Ariba Sourcing.

Notes and Restrictions

Sourcing with SAP Ariba Sourcing (4BL) is intended to cover the same business process as its predecessor Sourcing with SAP Ariba Sourcing (1A0). Since Sourcing with SAP Ariba Sourcing (4BL) leverages the advantages of the SAP Integration Suite, managed gateway for spend management and SAP Business Network (Managed Gateway for Spend&Network), do not implement Sourcing with SAP Ariba Sourcing (1A0) as of now. Existing implementations of Sourcing with SAP Ariba Sourcing (1A0) can still be used until further notice.

The following are the Restrictions on Requests for Quotation.

  • SAP S/4HANA Cloud
    • You cannot create a request for quotation that has no suppliers. Ensure that you add the suppliers (bidders) to the request for quotation. The suppliers must be registered suppliers on the Ariba Network.

    • An RFQ cannot contain service line items. SAP Ariba solutions do not support service line items.

    • The purchaser who creates an RFQ must not be an Ariba Marketplace supplier.

    • An RFQ cannot contain the follow-on document type with WK. SAP Ariba solutions only support the NB (purchase order) document type value.

    • You cannot send an RFQ with reference to a purchase requisition to SAP Ariba solutions.

    • You cannot send an RFQ from multiple SAP S/4HANA Cloud systems.

  • SAP Ariba Sourcing
    • SAP Ariba solutions do not support adding new line items to the request for quotation. Although the sourcing manager has the permissions to add line items to the request for quotation sent from the SAP S/4HANA Cloud system, SAP Ariba recommends that no new line items are added.

    • The sourcing request cannot contain suppliers that do not exist on SAP Ariba Sourcing. The sourcing request must only contain suppliers that exist on the SAP S/4HANA Cloud (business partners), SAP Ariba Sourcing, and the Ariba Network.

You can use this app to create RFQs in SAP S/4HANA. There are different processes that you can start from within the  Manage RFQs app.

You send your created RFQs later to SAP Ariba Sourcing, where the bidders and suppliers can place their bids. After you have decided which bidder or supplier should receive the award, you send the awarded quotation back to SAP S/4HANA. A purchase order or a contract is created automatically in the background. You can display it within the Manage Purchase Orders app or within the Manage Purchase Contracts app.

To request only price and quantity information or shipping costs, you send these RFQs later to the Ariba Network, where the suppliers can create their bids. These bids are sent back to SAP S/4HANA, where you can award one of them.

You can also create price requests in SAP S/4HANA and send them directly to your supplier using e-mail or as a printed version by mail. You receive the quotations from your suppliers and then create the quotations in SAP S/4HANA manually.
