I'm getting an Error for my Target: Unable to retrieve Data Extension using CustomerKey
I can see the Data Exension and do the mapping. And Additionally I can run data into the top level Business Unit (BU) no problem.
But once I add a "Partner IDs" Business Unit ID to my Skyvia Marketing Cloud Connection to Target a sub BU the insert doesn't work.
I have tried in the top level Business Unit (BU) and the inserts work great.
I have remapped and made sure all the settings are the same at the top and in lower level, sub BUs.
