Hi Ruchi,
- In my xsd in top second line it says
xmlns="<namespace>”
However in the other xsd (which is working fine), it says
xmlns:x12="<namespace>”
You should check how the second schema is importing the first xsd, not all XSD sintaxis is supported, is it being used include or import clausule?, for example i had problems with the dash character in the name of the files and i had to change them with the underscore character. Could you share your XSD ?, we can take a look.
Depending your PI version, your system supports more or less things. For example for PI 7.1: http://scn.sap.com/docs/DOC-3488
