I am confused with XS or XSA Development and have following queries.
- Can I use XS/XSA over S4 HANA On-Premise Edition.
- What is the exact difference between S4 HANA and HANA Express Edition.
- If I can developed Apps through ABAP in S4HANA, what exact purpose XS/XSA will be fulfilling.
- Do I need database access to develop XS/XSA Apps and can it disturbed existing S4HANA ERP standard tables.
