PROC HPFTEMPRECON performs temporal reconciliation on forecasts for the same series measured at two different frequencies. For example, the procedure can be used to reconcile monthly forecasts to quarterly forecasts for the same series, so that the adjusted monthly forecasts add up to the quarterly values. In order to perform temporal reconciliation, the high-frequency time interval specified in the ID statement must nest within the low-frequency time interval specified in the BENCHID statement. In the above case, months nest within quarters, so temporal reconciliation can be performed.

When working with data sets that use retail intervals, PROC HPFTEMPRECON might incorrectly issue the following error:

   ERROR:  ID interval is not nested in BENCHID interval.  Attempted use not currently supported.

The following example illustrates a specification in which the procedure incorrectly returns the above error even though the WEEKV interval nests within the R445QTR interval:

   proc hpftemprecon data=retailwk benchdata=retailqtr 
          outfor=temprec_outfor outstat=temprec_outstat;
      id wkdate interval=weekv notsorted align=beg;
      benchid qtrdate interval=R445QTR align=beg;
      reconcile predict=predict;
   run;

There is no circumvention for this problem.
