Why are default shipping addresses getting unset from SCA site for existing customers?

AI generated answer (using internal Slack threads):

Based on the conversations, the default shipping addresses might be getting unset from the SCA site for existing customers due to a few reasons: 1. NetSuite's Default Behavior: NetSuite's default behavior is to update the customer record with the shipping address entered during the drop ship process. This means that if a customer places a drop ship order, the address they enter changes the address in the customer record. 2. Use of Custom or New Address: If a custom or new address is used on the sales order, it doesn't get added to the customer record. However, if the 'Default Shipping' option is selected, it changes the default on the customer record. 3. Mandatory Fields: If mandatory fields like Country, Zip Code, etc. are not filled in when using a custom address, the system might remove the information upon saving the Sales Order. 4. Primary Contact Role: If a customer has a contact with a role of "Primary Contact" with a certain address, NetSuite might copy this to the Billing Address on all transactions. Removing the "Primary Contact" role from this contact can resolve the issue. To avoid these issues, you can consider using the 'Custom' option in the 'Ship To' on the Sales Order record. This allows shipping to an address which is different than the customer record, and it also doesn't add it as a new address to the customer record. However, this custom address is not stored, so it needs to be re-entered for each new order. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
