You might use the number of DEs returned to set the limit on a loop that iterates through each Data Element in a Element List. If the DataSet contains SQ (Sequence of Items) data elements, the method returns the total number of data elements, including data elements contained within sequences. If there are no SQ Data Elements, lpMaxLevel is set to 0.
