Hi Ravikumar,
->When we trying to add a Preview button on TI screen, we are getting the error which is attached below and those screens are created for Desktop and Tablet . even we are getting the same kind of error while we trying to Attchement EC to our custom screen
1.Preview model dialogue and Attachment EC reuse components can be used only for desktop device type.
FYI: Please check 9.6.2 Mobile Solutions in SAP Cloud Applications Studio SDK Documentation.
(Just to be sure, please raise this issue as another question so that other experts can help you)
2. In the meanwhile, create screens for desktop only and test.
Best Regards,
Fred
