Content (required):

create saas Neogtiation from an ebs quote request(RFQ PO). I would need to understand how to map data from a quote request into ebs of which I only have a simple query: SELECT DISTINCT h. * FROM apps.po_headers_all h, apps.po_lines_all l WHERE h.type_lookup_code = 'RFQ' AND h.po_header_id = l.po_header_id and how to create data mapping for the negotiation creation rest service. Then for the suppliers to be imported I would like to know how and which queries to use from ebs R12 for importing suppliers from ebs to Saas Fusion App considering all the data accompanying the supplier (address etc)
