Indexing, "Category_MinorCodes"

I upgraded from 4.1 to 4.7. Not sure if this has always been a problem or just with 4.7.

When I go to Maintenance > Re-Index, I get the following error:

Cannot find the object "Category_MinorCodes" because it does not exist or you do not have permissions.

Can't find a reference to this anywhere in code or in the DB. Any help?

This is not a standard nopCommerce table
Does this table exist in the database ?
If so, maybe you previously installed a plugin in v4.1 which may have created the table ?

Thanks. You're right. It's a work table we made for something in a past version. It was "hiding" under a different schema.

Is there a list of SQL tables needed for 4.7? I should clean out my DB. We actually started on 3.5, and used to have 2 stores on one DB, so there's a lot of junk in here I don't need.

There is not a list of tables as such - it does a select of tables for the criteria
I guess it finds the table then maybe does not have acces to do the command ?
See https://github.com/nopSolutions/nopCommerce/commit/f2ca7c47727c1bb45c53b6f6a33af6a0b75bbe49#diff-70e498894a376d9bc1ff4eb404a46e3f0c5c9df4ed316df4ef2aa2ee68af8dc6

I would take a backup of the database then delete that table and give it another try
