Management Reporter Data Mart Integration Issue with AX 2012 R3

Hi All,

I am trying to configure the Data mart in Management Reporter but the process never ends. When checked the logs, i found the below error:

Reader returned fewer objects for processing (26756) than expected (26924).

some warnings are also thrown which are as below:

Company cache missing ledger, 22565421671

Unable to load ledger, 22565421671, for transaction, 35637739936

Management Reporter Version - 2012 CU13

AX version - AX 2012 R3 CU8

We have Contoso demo data imported in AX and i think that is the only thing causing this issue but not sure what could be the root cause or corrupted data.

I have tried all the possible ways found on the internet but none of them are working.
