We are using SAP Netweaver Connector without problems to extract data of reports, extractors and tables from SAP R3 and running in QlikView Server. We have the processes created and running and login to SAP using a SAP User Account with User Type configured as a Service User.
For compliance things we need to change this user type from Service to System or Communication type. Is that possible without generate any kind of impact in actual SAP extraction processes?.
