Drafts show up on the list of implementations (IDs starting with “YY9_”). Trying to open them fails with error:
Enhancement implementation was not created with the key user tool, or was changed in an incompatible way with external tools. Enhancement implementation cannot be displayed or edited with the key user tool.
S/4HANA CLoud 2005
This will be fixed in Hotfix Collection 3 (end of CW 20) so drafts will not be shown in the list anymore.
In the meantime, these entries can be ignored and the app can be used as usual.
