Hi,

Aggregate functions are Sum, Max, Min, Avg etc., this are straight forward functions.

Aggr is an Advanced Aggregate function.

Difference between this two types are

Aggregation functions straight away calculate the value, where as Advanced Aggregate functions aggreates by given dimension.

For example

Sales:

LOAD * INLINE [

    BillNo, CostPrice, SellingPrice

    1, 1000, 1200

    2, 500, 650

    3, 200, 300

];

When we calculate Profit % (SellingPrice/CostPrice) by using

Aggregate functions:

= Sum(SellingPrice)/Sum(CostPrice) = 1.264 

Advanced Aggregation functions:

= Sum(Aggr(Sum(SellingPrice)/Sum(CostPrice), BillNo))  = 4 (1.2 + 1.3 + 1.5)

here the profit is calculated by billno and then it is summed up.

Hope this helps you.

Regards,

Jagan.
