Problem in error handling in SAX Parser

Question

My application takes xml message as input.
If a error was found while validating, an <Errors> <Error></Error></Errors> element is included in the orginal message and send back to the user.
While validation xml message I found an interesting problem.
Created a false entry for the root element attribute.
Traced method invocation.
First the call back error method is invoked,then the start element(stored the attributes inside the starElement to a instance variable).When i tried to print the attribute .As the error method got invoked first
if showed "null".
But when i created the same case with the child elements attributes
even though invoking of the methods happens in the same sequence
attributes got assigned and can print the attibutes values.
xml is schema vaidated .Is there any restriction that root element should not contain attributes.Can any one explain how the call back methods are invoked .

Hi Muruganand,
Is the data load failing while loading data or while activating?
if the data load is failing at activation, thers is nothing you can do except editing the records in PSA and then update them.
As far as i have seen, the data load to DSO fails in Activation and not while loading. this is the reason why the records are not collected in error stack
unlike if it is a cube, the data load fails while loading collecting the recods in error stack.
hope this helps,
Thanks and Regards,
Srinath.
