Hi @debashishghosh and @may_kwok
The origin code is an engine-private identifier linked to the value set in the load plan for the field origin. It’s stored on every record as a code to save space and improve indexability rather than storing the origin string everywhere.
For that to be missing/not found something has gone properly wrong - it implies a database row has been manually edited or deleted, either in the instance table or in the origin lookup table
Specifically, that origin code should be present in the SQL table i__origin and be referenced in the instance table - probably c_address_i.
I'm not aware of any way the engine could have created this mismatch on its own: there must have been some sort of forced data insert or update - have you populated the database in any way other than a standard data load?
