how to calculate SUM of Increase and decrease and summary of all

[Anonymous]

Hello 

I have a table with amonth of order for each item (F[Value]) and the date of order (conceted to DIMDATE Table) , I needed to calulated sum of orders in selected month and it's prior month , so I did below measures :

 Total = SUM(F[Value])

Prior Month Forecast = CALCULATE([Total], PREVIOUSMONTH(DimDate[Date]))

and I have Incease and decresed and total changed 

Increase the Quantity =  VAR PrevMonthOrder = [Prior Month Forecast]

    RETURN

        IF(SUM(F[Value]) > PrevMonthOrder,CALCULATE( SUM(F[Value]) - PrevMonthOrder), BLANK())

Decrease the Quantity =    VAR PrevMonthOrder = [Prior Month Forecast]

    RETURN

        IF(SUM(F[Value]) < PrevMonthOrder,CALCULATE( SUM(F[Value]) - PrevMonthOrder), BLANK())

 

Forecast Quantity Changed = VAR PrevMonthOrder = [Prior Month Forecast]

    RETURN

        SUM(F[Value])- PrevMonthOrder

 in the abouve table for header there is not any sum because my measures calulated them separatly . 

Now , I need to calulate Sum of all increased and decreased and changes , I know that would be some row 

 all the increase and decreasing without considering the top headers.

I know that might be a row context calulation , but I dont know how I should apply it .

I found answere: 
I have used this for decreasing : 

SUMX(FILTER(ALLSELECTED('Forecasting Folder'[PartNo]),[Forecast Quantity Changed]<0),[Forecast Quantity Changed])

and this one for increaseing : SUMX(FILTER(ALLSELECTED('Forecasting Folder'[PartNo]),[Forecast Quantity Changed]>0),[Forecast Quantity Changed])
