The choice of procedure is made on the following relevant tabs for Basic RFx or Advances RFx: - Basic RFx - You can find this on the tab *Sourcing event information* - Advanced RFx - You can find this on the tab *Procedure * The procedures that can be selected are: - [Open procedure](https://mercell.atlassian.net/wiki/spaces/MKB/pages/196280335149/Procedures+and+Rounds#Open-procedure) - [Restricted procedure](https://mercell.atlassian.net/wiki/spaces/MKB/pages/196280335149/Procedures+and+Rounds#Restricted-procedure) In addition to these, an electronic auction can be used in the request (in *Advanced RFx *only).  The choice of procedure influences how the request will proceed. You can find more detailed descriptions of each procedure below. ## Open procedure An open procedure is a procurement procedure in which the request is published as an open procedure in the* Supplier Portal*. All bidders can then make a bid to the request. Open requests can be published, not only on the *Supplier Portal*, but can also be sent by e-mail, in which case the bidder is sent an invitation to leave a response to the request.  **Open procedure publication channels:** - Supplier portal - E-mail ## Restricted procedure A restricted procedure is a procurement procedure in which the request is published to selected bidders directly by e-mail and only invited tenderers can submit responses. Unlike in an open procedure, this type of request cannot be published publicly on the supplier portal. **Restricted procedure publication channels:** - E-mail*   * *Article ref: 070820251238* ** **
