IDOC RFQ and Quotation (MM-PUR-RFQ)

HI,

To send a RFQ to a vendor,  I can use the REQUOTE idoc. THis is working perfectly. We send the RFQ from SAP to external vendor portal.

I would like to know which idoc i can use, for the quotation which is send back from the vendor.  From the portal to SAP and it updates the RFQ in ME47 with the price.

Thanks a lot

Regards

B
