hi,
1) install the SAP Connector software
2) find the transports here : Program Files\Common Files\QlikTech\Custom Data\QvSAPConnector\Transports
install them on the SAP systems
3) find the ScriptBuilder here ProgramData\QlikTech\Custom Data\QvSAPConnector\ScriptBuilder
configure and reload when transports are OK.
4) generate scripts and paste them in other QVW script.
