Today i faced the problem that there is no way to change the SKU of a product using the webinterface of commerce.

So i found the table that it could be changed in using this mysql-select:

SELECT * FROM   information_schema.columns WHERE  table_schema = 'my_database_name'  AND column_name IN ( 'sku' );

i simply had to change the values in the SKU field in the "commerce_product" table
