soap header information to each operations

, ,
1

in webMethods 8.0, provider wsdl is created with multiple operations.
we have 3 parameters in soap header which are handled by handled request.

I have to add additional code, in each of operations, based on soap header parameters.

How to pass soap header parameters to each operations.

I tested this by save/restorepipeline. soapHeaders document type is not available in the each operation.
Any help, please, is it because of something wrong in namespace declaration ?
