Hello ekrammohammad,

I think, there in an incinsistency in the archiving system.

You can try to reset the archiving-system for Alarmlogging
and Taglogging.
You can do this if the project is open in the WinCC-Explorer,
but not in Runtime.

The can you execute via Run:

ccarchivemanager.exe -resetall

But this deletes all Runtime-Data of Alarmlogging and Taglogging.
And it sets the Archive-Configuration of Alarmlogging and Taglogging
to the default values (1 day / 1 Week).

Regards
