Thanks for your answer , but i know when i check box (Reverse sign- not assets) then all values will be Reversed , mean i will have positive sale and negative expences in report. up to this point, it is fine but
When it is mentioned that " Reverse sign (Not Assets) its mean that it should not effect assets i.e Assets shuold not come up with negative values , if this is case then i think Reverse sign ( not Assets) is confusing , because reverse sign also effect Assets. ( If i check this box then it will effect every item including Assets).
Hope i was able to explain it , but i can send screen shot for further explanation.
