Min() returns the lowest numeric value of the aggregated data in the expression, as defined by a group by clause. By specifying a rank n, the nth lowest value can be found.

Examples and results:
Add the example script to your document and run it. Then add, at least, the fields listed in the results column to a sheet in our document to see the result.
Example 1:
Temp:
LOAD * inline [
Customer|Product|OrderNumber|UnitSales|CustomerID
Astrida|AA|1|10|1
Astrida|AA|7|18|1
Astrida|BB|4|9|1
Astrida|CC|6|2|1
Betacab|AA|5|4|2
Betacab|BB|2|5|2
Betacab|DD
Canutility|DD|3|8
Canutility|CC
] (delimiter is '|');
Min:
LOAD Customer, Min(UnitSales) as MyMin Resident Temp Group By Customer;
| Result field (Customer) | Result value (MyMin) |
|---|---|
| Astrida | 2 |
| Betacab | 4 |
| Canutility | 8 |
Example 2:
Given that the Temp table is loaded as in the previous example:
LOAD Customer, Min(UnitSales,2) as MyMinRank2 Resident Temp Group By Customer;
| Result field (Customer) | Result value (MyMinRank2) |
|---|---|
