GetReportRequestList and Marketplaces?

[philsmy]

Normally what we do is ask for a report and then go away and use get_report_request_list with the report type to see if it is done. This stops us repeatedly asking for a report when there is one already available.

What I am seeing - in this case it is with GET_MERCHANT_LISTINGS_ALL_DATA but probably the same for all reports - is that there is no way to ask for or figure out if the reports in get_report_request_list are for the right marketplace!

If I do a request_report(report_type, marketplace_id_list: [marketplace_num]) where marketplace_num is Canada (A2EUQ1WTGCTBG2) for example and then do the same but with marketplace_num for America (ATVPDKIKX0DER) there will end up being two reports in the report request list, but it is impossible to know - from either the metadata or the actual report data! - which one is which.

Any ideas on what to do here? Or just say to hell with it and ask for a new report every time and wait for it to complete?
