[Bug] REST API: Update special prices does not set values for all store views

[JoryHogeveen]

Preconditions and environment

• Magento versionL 2.4.7-p3
• Anything else that would help a developer reproduce the bug

Steps to reproduce

1. Create multiple websites and storeviews
2. Use de REST API to update a special price for a website (any store view ID)
3. Verify change, you'll see that only the storeview for the ID you passed is updated and Magento does not override the settings for the other storeviews, these are still on "Use Default Value".

Expected result

Since the special pricing attributes are in website scope, I would expect all store views to be updated, not just the single ID passed in the endpoint.

Actual result

The special price values are only updated for the store view ID that is provided through the payload, all the other storeviews are not synced.
I consider this a bug since the default Magento 2 admin handles this automatically. When you change the value for an attribute in the website scope, all other storeviews are also updated. IMO the REST API should behave the same.

Additional information

No response

Release note

This bug enforces anyone using the REST API to provide the special price for ALL storeviews in that website, which is hugely redundant and also enforces an extra REST API call to get these IDs.
Special prices are critical data since incorrect values could result in invalidly priced orders.
Therefore I set this to S1 severity.

Triage and priority

• Severity: S0 - Affects critical data or functionality and leaves users without workaround.
• Severity: S1 - Affects critical data or functionality and forces users to employ a workaround.
• Severity: S2 - Affects non-critical data or functionality and forces users to employ a workaround.
• Severity: S3 - Affects non-critical data or functionality and does not force users to employ a workaround.
• Severity: S4 - Affects aesthetics, professional look and feel, “quality” or “usability”.

Hello @JoryHogeveen,

Thanks for the report and collaboration!

We have tried to reproduce this issue in the latest development branch i.e. 2.4-develop and the issue seem reproducible for us.

Below steps we followed to reproduce the issue:

1. Go to Stores -> Configuration -> Catalog -> Catalog -> Price and update Catalog Price Scope as Website.
2. Create multiple websites, stores, and storeviews.
3. Edit any product, and choose the scope (We chose Spanish):
   
4. Click on Advanced Pricing and add a special price for the product.
5. Save the product. This will also update the special price for the Spanish 2 store.
6. But if we use rest API as below:

http://local.magentoissues.com/rest/all/V1/products/special-price
{
  "prices": [
    {
      "price": 200,
      "store_id": 2,
      "sku": "product_dynamic_1"
    }
  ]
}

7. It is updating only for the mentioned store id. but it should update for all stores under that website.

Hence confirming the issue.

Thanks
