You have a requirement to extend a PDI field to the Web Service Query EmployeeIn -> Operation indBasicDataByIdentification but field is still missing in WSDL. WSDL only contains the definition of the fields, but they are not associated with query structure.
Reproducing the Issue
Reference Field Bundle is for Interface II_QUERY_EMPLOYEE_IN, Operation FIND_BASIC_BY_IDENTIFICATION.
There is no Reference Field Bundle for the web service operation with message type being for the Request.
Currently it is only possible to extend the structure of operation: FindBasicDataByIdentification.
