Per Lo, factory didn’t afford your instruction due to all CO form in Indonesia must be applied by system developed by the government.
Factory cannot delete invoice number and input several addition on line 9 due to the form only available for one line for quantity and one line of value (FOB) that must be filled (signed with red star). Otherwise they cannot save and send the CO application form to Trade Dept.
Please advice should factory apply CO with prior C draft or not due to the system doesn't afford your instruction
