Problem Note 47368: Forecasts might be incorrect when FCST_DISAGG=1 and FCST_DISAGG_METHOD=1
 |  |  |  |  |
Forecasts might be incorrect in the SAS® Revenue Optimization Suite when FCST_DISAGG=1 and FCST_DISAGG_METHOD=1. Specifically, when FCST_DISAGG=1 and FCST_DISAGG_METHOD=1, some observations might incorrectly be excluded from the baseline forecast process, resulting in incorrect forecasts.
There are no errors or warnings.
The workaround is to disable forecast disaggregation by setting the model specification FCST_DISAGG=0.
