Error related to data refresh in file: tmmdmodeltm.cpp

[Lassith]

Hi,

I have developed my report locally and refreshed data with no errors and also no errors has speen spotted anywhere in the report locally.

Now im publishing the report to server. Tried to refresh the data and got an error related to data refresh in server. Has anyone faced similar problem?

"An error has occurred.

Several errors occured during data refresh. Please try again later or contact your administrator.

[0] -1056964608: An unexpected error occurred (file 'tmmdmodeltm.cpp', line 7611, function 'MDModelTM::IsAttributeHierarchyQueryable').
[1] -1055129594: The current operation was cancelled because another operation in the transaction failed."

We are using version: Version1.19.8779.19175(January 2024). 

Could someone help me out, what this file does or what this error-message refers to?

Thanks!

did you figure this one out? I also have a published report that was working fine until Dec 2025 and for some reason failed to refresh and met with this error.

That sounds like a bug. You should log an official support ticket with Microsoft
