Hi I'm facing this issue clicking on configure button :

com.sap.custdev.projects.fbs.slc.cfg.exception.IpcCommandException: Error while loading KB. Knowledgebase not found for KB ID:KB Name: KB Ver: Product ID:Product Type:->null:null:null:080000379:MARA.

on SAP KB is properly set, CRMRFCPAR has blank in SEND_XML parameter. hybris initial load is running correctly. there is something that has to be configured on hmc? could you explain how Hybris work with KB ?
