Thanks,
Good to hear that in and out is working. Does help to identify the specific version to which you are referring. (For immediate assistance and for others in the future reviewing the thread for similar "issues").

The products_upc field is something that is added to the products table by some other process... EP4 allows updating/modifying it because it recognizes that it is in the database. Because 1) that field is not something created by EP4, 2) it was added by some other process/program, and 3) that there is no issue with interfacing it using this plugin. Technically it is something to address elsewhere in the forum. (The plugin that added the field, or a new thread.) But, that's no reason to not at least provide some more info to possibly be directed elsewhere.

Am curious about which version of EP4 is in use to validate operation.
