How to change the SKU with REST API?

[antsem88]

Call:
PUT /rest/V1/products/{sku}

Request:
{
"product": {
"sku": "modified.sku",
"name": "modified name"
}
}
Result:
The name has changed, but the sku is the same. How can I change the product sku?
Thanks

SKU is a unique key for products, it can't be changed via the API. Our reasons for doing this is based on feedback from partners integrating to ERP & PIM systems it was desired to have a valid key that can be used by both systems.

@choukalos How I can fix this via preference?
