I am new to Odoo. 

Issue: updated a new report for 'request for quotation' under puchase order. updated in the views also. but now while printing the RFQ getting error as missing record(record might be deleted).

Here is my screenshot: where for RFQ updated a new document

I tried to cross check: in report of RFQ as Qweb view earlier it was showing 3 but now only showig my new report how to retrieve other reports. and is there any steps or video to do these steps?

error: RPC_ERROR

Hi,
Did you define the views for the model ? Like tree and form view, if not define those views and upgrade the app and see.
