Fix a Value to a Sample Load

Hello everyone !

I have a task where I need to create a sample table which as 40 random rows in it from an existing tab and I have already this script using Sample() but sample doesn't return a fix value and I would like to know if it is possible to have it return only 40 values (for now it returns between 30 and 60 rows).

[App_Name]:
DT_MAJ,
ID_APL as ID,
LB_APL as Name,
MC_MAJ;
SQL SELECT *
FROM "LUAU_UCR".dbo."TB_Application";

LET vTotalRows = NoOfRows('App_Name');
LET vPercent = (100 * 40 / $(vTotalRows)) / 100 ;

[Sample_Table]:
QUALIFY *;
Sample $(vPercent) LOAD * Resident App_Name;

You could either generate this sample in SQL itself or use the QlikView prefix First rather than Sample, maybe sorting by a random value you generate in your initial load.
