Any Body Would Like To Explane The Below Points:
I am Confused at These Syntax.
1) <FieldName>...I saw some syntax Like < FieldName>, What is The Use of These "< >" Brackets.? Not In Set Analysis.
2) Sum( :: FieldName). What is The Use of :: (Double Colon in Set Analysis).?
3) Load @FieldName, What is The Use of @ Sign before FieldName in Load Script.?
4) FirstSortedValue Function, Can We Get The Same Output By Using Count and Sum Function.Instead of FirstSortedValue.?
Your Explanation Whould Be Gighly Appreciated.
