Define Shipping data for Plant (STO)

Hi Experts

Question about assigning the customer code in "Define shipping data for plant" configuration.

Normally, the actual internal customer code is not created in golden client. how to handle this ?

I can think of two options

1. Open production client and assign the customer code"
2. Create new customer in golden client and save. Transport to other entities.
3. Is there any other option whereby not required to create but still force to maintain the customer and be able to transport to other clients.

Thanks for responce.
