Qlik SAP Connector is not free, it requires a license. For pricing you need to talk to a Qlik Sales representative or your Qlik Partner.
If you do not know who your local representative is, you can reach out to Qoncierge | Qlik for help.
you should talk to your qlikview account manager or to the company that sold QlikView to you.
On the web you can find the QlikView pricing, e.g. here:
with the following license price per server:

In our company we used Xtract QV, an SAP Connector for Qlikview provided by Theobald Software. The price can be found on the website of the vendor.
