Generate Next Number Sequence by x++ code in axpta

// This is one way
static void Nextnumseq(Args _args)
{
         NumberSeq num;
        kanhaNum _kanhaNum; //Table Buffer
        ;

        ttsbegin;
           num = NumberSeq::newGetNum(HrmParameters::numRefJournalNum()); // Parameters Table
          _kanhaNum.NextNumseq = num.num(); // Next NumberSeq generated
          _kanhaNum.insert();
          num.used(); // Mark the Number as Used
      ttscommit;
}
//The other Way is

static void testnumseq(Args _args)
{
     kanhaNum _kanhaNum;
     ExtendedTypeId id = TypeID2ExtendedTypeId(TypeId(kanhaNumber));//EDT NAME

     NumberSeq num = NumberSeq::newGetNum(NumberSequenceReference::find(id));
     ;
     //_kanhaNum.NextNumseq = num.num();//NEXT NUM SEQ
     num.used(); // mark the number as used
     info(num.num()); // NEXT NUM SEQ
}
