Map issue key from external source with Issue Cube

Hi,
I’m trying to add data from external SQL to Issue Cube. I was mapped columns like this, but i get an error.
Missing Issue dimension member for {“issue_key”=>“ESP-17177”, “x_typ_transakcji”=>“Sprzedaz”} and new record creation is not allowed.

If marked skip missing, 0 columns is imported

Problem has been solved
