Error App Fiori : Could not instantiate data source "DS_1" for query "/ERP/SFIN_V01_Q2001".

Hi all,

I have a problem when using app: Cost Centers - Actuals. It showed error : Could not instantiate data source "DS_1" for query "/ERP/SFIN_V01_Q2001" and Query /ERP/SFIN_V01_Q2001 is unknown.
What should I do ?

Best regards,
