I have a writable external data source with 2 external objects:


  • VIN__c - Unique External Id (maps to VIN column in Car table)
  • Plant__c - Lookup to custom object Plant


  • Car__c - External Lookup to Car (maps to CarVIN column in Part table)
  • Plant__c - Lookup to custom object Plant

When a Part is inserted it shows up as a child on the Plant layout. However the external lookup field Car__c shows as blank only on the related list. If I view or edit the record the external lookup is there.

This issue does not exist in Salesforce Classic.

Is this an undocumented bug or am I doing something wrong here?!

This was caused by our OData connector; it had a bug in handling ORs in its query.
