SQL Error 8103 while data loading

Hi all,

We were loading data to a cube by an IP during which we faced an error. For that moment , the old request was deleted from target and step was repeated and chain got completed successfully. But I want to know why did error happened ? I was unable to get much information regarding this issue.

Error Messages ::

1) SQL Error:8103

2) Errors in source system

3) ORA-08103 : object no longer exists

I also looked into sm21 and found " Database error 8103 at FET" . Main points I want to know about this are ::

1) why this error occured ?

2) what is proper solution for the same ?

Regards,

Arpit
