OCBC GIRO is the GIRO format without BIC codes.
All GIRO with Invoice format is the format with BIC codes.
If you are using All GIRO with Invoice format, there are a few things to note:
1) If you have registered to use the GIRO file with specific Transaction Type Code such as Payroll or Management Payroll, when you process the payrun, kindly process those employees in separate payruns (e.g. Payroll employees in one payrun and Management Payroll employees in another payrun) and generate bank files based on the various payruns.
2) However, for those who are using only one payroll, it is not necessary to process separate payruns.
