I know this a bit of a late reply. But still answering this so that it might benefit someone!
You could use the function ACT_LOCATION( ) to exclude the location.
For example, you want to exclude Location XYZ from the calculation, you could use the function like below:
Step: Calculate Independent Requirement
IF
Location = XYZ
ACT_LOCATION( )
= 'XYZ'
Row: Independent Requirement =
SUM(
Row: Forecast
ELSE
Row: Independent Requirement =
SUM(
Row: Forecast
Row: Distribution Demand
)
ENDIF
Hope this helps.
