I am trying to create a new ranking system and keep getting the following:
The formal parameter "@mkttype" was not declared as an OUTPUT parameter, but the actual parameter passed in requested output.
Thanks for reporting this. The error you were seeing when creating a new ranking system ("The formal parameter "@mkttype" was not declared as an OUTPUT parameter...") was caused by an issue on our end, and it has now been fixed.
Please try creating your ranking system again. It should work as expected. If you run into any further issues, please let us know.
