Systemverilog 2D dynamic array constraint, define max

SystemVerilog

I encounter a question: generate a 3x3 dynamic array with one of the value being highest of all. 
I came up a complicated method, that will call a function which will use associate array count frequency and find max at the same time. Then set count(max) == 1. Running in simulation, looks like, rand variable cannot be used in function. So I do don't know how to achieve by now.
May I know if there is any easier way to do this?

In reply to aaaaaa:

class abc;
  rand int unsigned dyn_array[][];
  rand int unsigned highest_value_row;
  rand int unsigned highest_value_col;
  
  constraint c1 {
    dyn_array.size == 3;
    foreach(dyn_array[i]) {
      dyn_array[i].size == 3;
    }
  }
      
      constraint highest_value {
        highest_value_row >=0 && highest_value_row <= 2;
        highest_value_col >=0 && highest_value_col <= 2;
        foreach(dyn_array[i,j]){
          dyn_array[i][j] < 100;
          if(i != highest_value_row && j != highest_value_col)
            dyn_array[i][j] < dyn_array[highest_value_row][highest_value_col];
        }
      }

endclass

      
module abc;
  initial begin
    abc aa;
    aa = new();
    aa.randomize();
    foreach(aa.dyn_array[i])begin
      $display("%p, %d, %d, %d",aa.dyn_array[i], aa.highest_value_row,aa.highest_value_col,aa.dyn_array[aa.highest_value_row][aa.highest_value_col]);
    end
     aa.randomize();
    foreach(aa.dyn_array[i])begin
      $display("%p, %d, %d, %d",aa.dyn_array[i], aa.highest_value_row,aa.highest_value_col,aa.dyn_array[aa.highest_value_row][aa.highest_value_col]);
    end
 end 
endmodule

May be this is what you are looking for from your description. See if this matches your requirements.
