the xsd type date does not exactly correspond to the abap type STRING in sproxy

Hi,

I am getting a warning in in SPROXY like "the xsd type date does not exactly correspond to the abap type STRING".

earlier the field type in PI was 'xsd:string', but now it has been changed to type 'xsd:date'. While regerating the proxy I am geeting the warning like above and the Techn.Type of ABAP attributes is showing as STRING in sproxy(properties of External view). The XSD type has been changed to 'xsd:date' in the xsd attributes but the Techn.Type of ABAP attributes is not changing from STRING to DATE.

Thanks,
