Dear all,
problem is solved at the moment.
SAP Note 1775432 has solved the problem.
In the old backend system the time zone was CET.
(not the same time zone as the operating system time zone)
The new upgraded backend system had time zone UTC.
Now both are the same (transaction ZTZAC) and the values which are changed with the firefighter are displayed in the ff-log.
BUT next year we will connect another backend system with GRC and there it is not possible to change the time zone of the backend system.
Does anyone know how to solve this (mapping table?)
BR
