Suppose I have records exported from source which includes records which are already in partial sandbox (Salesfoce Ids will be same for such records in source and partial sandbox) and some new records which are not present in partial sandbox. I performed
Upsert on partial/full sandbox based on salesforce
Id instead of using
external Id. Update was successful for existing records but insertion failed with error.
Error: INVALID_ENTITY_FOR_MATCH_OPERATION_ERROR]. Message [invalid cross reference id]
Is it not possible to insert records into partial sandbox by performing upsert operation based on Salesforce ID (to find existing records)?
