we have the following SAP ECC 6 HCM system:
We're still running ESS/MSS on an old Java Portal.
Can we use an app for starting/approving leave requests?
Is it just possible via a Fiori App? Is that possible with our environment?
Then we need a Gateway server, right?
Currently we're building up a S/4 HANA system landscape (including Gateway server and CPI).
Could we also use that to run the Fiori Apps?
Thanks in advance!
