Consult the product number and manufacturing number
Thread Content
I noticed that in some tables on the Liaobiao site, there are both a product number and a manufacturing number column; what is the difference between the two? How to write it?
In our company, product numbers are assigned according to the product type, while manufacturing numbers are determined based on the sequence number used during production after the contract is signed
The numbering for each company is not necessarily the same; each company has its own method, and there is no uniform standard. There are also those with the same manufacturing number and product number.
Different companies have different regulations; you can set your own rules. (In our company, the manufacturing number is the same as the product number.)
