Product Id

I am setting up a company store. I am currently importing products from our CRM. I have entered the ids into the import.csv. but after the export.csv the ids return to the original ids. Any idea why I cannot change them?



CRM product id format is like this- 571852000001427037



Cs-Cart product id format is like- 315



Why can't I change the product id to the correct format?

Database schema defines it as an unsigned int. The length varies by version. Suggest you use your old IDs as product_code or as a product feature. In CS cart, product IDs are an entity in the database and are an auto incremented primary key.
