show cause memo / fraudulent act of staff / is the approving officer liable?

good morning.aug7,2012-bank transactions are processed online/system/files are uploaded.in one of the transactions (php5,000 to be credit to another bank-peso account), processor changed/altered/tampered the data. processor made it as USD5,000*42.48= PHP212,400.00. officer forwarded the transaction to courier. it was deposited. account holder withdrew half of the php212,400.00. error discovered aug9, contacted courier aug10. officer was informed aug31, error reported to management sept12. according to staff, he overlooked/misinterpreted the currency. is the officer liable or shld the officer pay?

is the officer required to review the data and approve the same?

transactions are processed thru a system ( uploading of file transaction ). there are no operations manual/guidelines that officers are required to review every single transactions that will be uploaded in the system. the uploaded files in the system are assumed to be correct because the source file are protected.

if that is demonstrable then that can be the defense.
