ERROR: Can't change quote owner. Enable quotes without parent opportunities.: Owner ID, fields [OwnerId]

Issue

For now, there is only one way to change a Salesforce Quote owner after the Salesforce Quote is created.
(Please refer to https://trailhead.salesforce.com/trailblazer-community/feed/0D54S00000A8oKySAJ). By default, the Salesforce Quote owner can't be changed manually or through API.

Solution

1. Log into Magento 2 admin.

2. Open ‘Salesforce’ -> ‘Manage Mappings’.
   
   

   Open

   

3. Open 'B2B Quote mappings'.
   
   

   Open

   

4. Find all records with ‘OwnerId’ ‘Salesforce Attribute’ and edit them.
   
   

5. In 'Magento -> Salesforce Settings', set the 'When' field value to 'Insert Only’.
   
   

6. Press ‘Save Mapper’.
