the transactions on voucher do not balance as per accounting currency reporting currency error on posting a production order pick list

Hi,

I have upgraded from AX 2012 R2 CU7 to CU8. we are getting the following error when posting a production order pick list : "the transactions on voucher do not balance as per accounting currency reporting currency ". i did not find any hotfix to fix this problem.

This upgrade was there 2 days in production , can i just rollback the model database without restoring the business data(MicrosoftDynamicsAX).

Thanks in Advance.
