SAP Fiori development newsletter May 2023 (issue #22)

It’s hard to believe we are already in May. SAP Sapphire is coming soon, so expect to see some exciting announcements. While much of the focus will be on new low-code / no-code capabilities, there will also be some pro-code goodies on display. We have some updates below and stay tuned for more information in the next issue.

If you want to meet with fellow developers and the SAP engineers who build our professional development tools, I encourage you to join our monthly SAP Fiori elements and SAP Fiori tools roundtable group.
