I saw 2 DocTypes, Request For Quotation and Supplier Quotation.
When I create Request For Quotation, I can create Multiple Supplier Quotation.
My confusion was how are they connected in the database. I can’t find any field in the DocType settings which links them. I though find that in 'Connection" tab, they are getting shown. And when I click them, Supplier Quotation in the Connection Tab, I get redirected to the Supplier Quotation with the filler ‘Request For Quotation Equals {RFQ_ID}’ But where is this filter coming from since there is no Request For Quotation field in the DocType.
