As You know Adobe ended support of Flash Player on December 31, 2020. You might see that flash content doesn’t load / render or there is an error message saying that Flash is not supported, e.g. :
Today I receive information from SAP that:
Our development team is working on a new implementation of NWA applications that use Flash. Our target is to release the new implementation of System Overview with 7.50 SPS 20, which is expected to be released in March. The following note will be updated when we have more details and timelines: 2981308 – New implementation of Flash based NWA Applications.
The SAP Note 2477654 provides some alternatives to monitor the system.
