1. YES -> the script language is the same as QlikView with some small exceptions:
- There are some new script functions pertaining to geo fields and to date fields.
- Also the syntax for soucing a data source refers to individual data connections stored in a repository (rather than everything being a one off.
Go to the 'load editor' in Qlik Sense, instead of 'edit script' in qlikview.
2. YES . However QlikView provided some native connectors which are still in the process of being ported over to Qlik Sense (Salesforce, SAP etc...) These will be available in the next few months. In the meantime you can institute a global setting to revert qlik sense into understanding qlikview script that uses these connectors as long as you develop the script in qlikview first (and have installed the connectors). Evaluation licenses would be need for qlikview and any licensed connector (SAP) to trial this ability.
