WinCC Configuration Tool - Single Messages Error

Hi!

I was wondering if someone could help me.
I'm having trouble with the WinCC Configuration Tool. I'm working on a project and when i import the project data to the Excel (through the wincc configuration tool) i get the following message box:

(Error!) Not all limit value monitoring could be generated! Errors occurred while reading the object! An overview of all the errors which have occurred is provided in the 'reading errors' table.

When i open the Reading error sheet i have a list with the same "Table type" and "Error text". The table type is relate to the "Single message table" and the Error text is "The set message class or message type does not exist!". In the reading errors table i see that the errors arerelated to message numbers associated to a specific Message Class in Alarm Logging, but i've tried to create a new Message Classe and change the messages to that class but i keep having the same error.

Does any one have a solution to this issue.

Thank you in advance.

Best regards.

Hello, guys!

thank you in advance
