Ax has functionality built-in to generate random numbers. You can use the Random class for this purpose. Like this:
static void RandomGenerator(Args _args)
{ Random Random = new Random();
int myrandomnumber;
;
myrandomnumber=1 + Random.nextInt() MOD 100;
info('Number '+int2str(myrandomnumber));
}
In the above example, Ax will generate a random number in the range from 1 to 100.
Though the random class gives you integer values, you can use it to generate random real values as well.
static void RandomGenerator(Args _args)
{ Random Random = new Random();
real myrandomnumber;
;
myrandomnumber=(1 + Random.nextInt() MOD 1000)/1000;
info('Number '+num2str(myrandomnumber,0,3,1,0));
}
This example generates random numbers in the range 0.001 to 1.000.
The use of this function comes with a warning:
The chosen numbers are not completely random because a definite mathematical algorithm is used to select them but they are sufficiently random for practical purposes.
So, good enough to use in an ERP system.

You'd better use System.Random. The Random in AX does not use a seed and always returns the same random numbers
ReplyDeleteTo use a seed you can use the RandomGenerate class.
DeleteFor example:
int i;
int randomNumber;
RandomGenerate randomGenerate;
randomGenerate = RandomGenerate::construct();
randomGenerate.parmSeed(new Random().nextInt());
for (i = 1; i <= 10; i++)
{
randomNumber = RandomGenerate.randomInt(1, 6); // get a random integer between 1 and 6 inclusive
}
