BAPI or BAdI which can maintain Asset Class and Capitalization Date field(ANIA-ANLKL and AKTIV)?

Internal Orders need to be created from I/F, but we need to fill the fields Asset Class and Capitalization Date in the Investment tab on Internal Order master. Is there any BAPI or BAdI which can maintain Asset Class and Capitalization Date field(ANIA-ANLKL and AKTIV)?
