inbound interface for payroll

Hi All,

I have been asked to build a interface where in data is loaded in SAP in IT 0221 from a legacy input file that is recieved. A batch process has to rum to load this data in fields like wage type, amount, tax authority, check date pay id and OC reason of infotype 0221 with subtype Manual payment.

As a part of this inbound interface reports are genrated which segregate information in file by the subsidary code and grant type fields of legacy input file.

PLZ Suggest what approch should be followed BDC can be helpful to load the load the data????

Plz provide with any useful link or some sample code that could be applicable.

Satifactory answers would be highly rewarded.

Thanks,

Naveen
