I'm currently using service layer to delete addresses of a business partner.

Now I want to delete all existing addresses.

First I tried to use PUT as update method. Is this method no longer available since version 9.2 PL08 or 09? When I try to use PUT method, I always get an error message: internal server error.

Now I am using the PATCH method for my update. It works well when I delete or add one address.

But I can't remove the last address of my business partner.

I send the following request to delete all addresses, but this will not work (Response is 204 No Content). It doesn't matter if I set B1S-ReplaceCollectionsOnPatch=true or not.

How can I delete all entries of business partner addresses?

PATCH /b1s/v1/BusinessPartners('XYZ')

B1S-ReplaceCollectionsOnPatch=true
{
  "BPAddresses": []
}
