Spending some time coming up with an SKU naming strategy can help you. You’ll be able to make it easy for team members to read and understand what each SKU represents. Use a value that is meaningful to your organization.
Ultimately, your SKU is a way to record important product information, so the more straightforward it is, the better for everyone.
Sticking to alphanumeric SKUs and substituting “-” or “_” for space is always the safest and best bet.
E.g. Your app name: Social Point, Submit year: 2020 = Your SKU is: Social_Point_2020
