How SKUs are generated

Every product can have only one SKU and every SKU has to be unique. Duplicate SKU-s are not supported. 

Example: MME.0038447.11B

In this example, the prefix MME stands for Materials, Metal (M - Materials, ME - Metal), the number 0038447 means, that this is the 38447th MME product and the suffix 11B means that the product revision is 11B.
