MC.9 differences

Hello,

Every time we execute the MC.9 transaction it returns a different value (as shown in the picture), even tough we are running the report for a period of time already closed. I know there is a program to correct the MC.9 but I haven't been able to find it. Does anyone knows any way to correct this? The two report results showing in the pic below were taken 2 minutes apart from each other.

Thank you in advance
