so the main problem is we have different categories and different suppliers that we add for the expenses on monthly bases so when you go to expenses and you filter by month you will see the total amount down and the details of every transaction, and when we go to report < profit and loss per month we see a different number other than the one in the expenses at the same time some suppliers is not shown in the report so we see big difference in pricing 

unfortunately i cant attache more than one attachment to show you the difference but as you can see its around AED 33 K and in the report it show the same but with AED 17K
