Hi Udara,
As Isuru mentioned above, you might not have enabled the response return
configuration in DSS. If you need to return a value for database update
statement, you need to set the following setting.
<operation name="addEmployee" returnRequestStatus="true">
<call-query href="addEmployeeQuery">
<with-param name="employeeNumber" query-param="employeeNumber"/>
<with-param name="lastName" query-param="lastName"/>
<with-param name="firstName" query-param="firstName"/>
<with-param name="email" query-param="email"/>
<with-param name="salary" query-param="salary"/>
</call-query>
</operation>
Thanks,
Chanaka
