IVUL - 33  Match IVM History to IVHxx File

This utility sets reads the monthly sales history file and resets the smaller 12 months sales history array in the IVM file to actual.  The smaller history array can be viewed using the “H” icon on the tool bar. Since an array in memory is much faster than reading a file, BSMGR uses the array whenever possible so as to operate faster.  The much larger montly sales history detail can be viewed via the monthly history tab in IVM.  In theory they should be the same, however, running the history roll (IVHR) multiple times in one-month can cause the to be different.
