Machine-made sand codes are not allowed to display commodity codes.

Machine-made sand code shows that commodity code is not allowed, which may be due to the following reasons:

1. The coding method is wrong, so it should be selected from the commodity coding library.

2. There is no commodity information in the commodity code database, which needs to be entered manually.

Please judge and operate according to the specific situation. If the problem still exists, it is recommended to consult professionals or relevant institutions.
