Number Sequence Changes in 2012 - NumberSequenceReference Table

Hi,

In DAX 2009 I could get the next number sequence by calling the following code:

numberSequenceReference = InventParameters::numRefTransferId();

    numberSeq = numberSeq::newGetNumFromCode(numberSequenceReference.NumberSequence);

But in 2012 the NumberSequence field has been diminished. What is the new procedure to get th next number sequence?
