We ran into a critical issue when running the financial consolidation using financial dimension combination in AX 2012.
ISSUE: System was summing up the transaction amounts by date and was updating data into wrong financial dimensions in the consolidation entity.
SOLUTION: A hot fix was available for this and this worked fine after we applied the hot fix. (Please ignore if you already have come across this).
NOTE : This hot fix is not part of the CU2 update yet but may be included in the CU3 which is slated to release somewhere during JUNE/JULY this year.
