• Upon future investigation I determined most of the Access tables I tried to upsize were missing Primary keys.  I will tell the developer to add them. 

    However, a handful of tables errored out and did not leave an error message.  I'd like to know if there is a way to determine what caused these tables to fail?   Is some sort of log generated?
