Load future rows in Demantra

We want to load future rows to create combinations for items - locations. These are not sales history. This is just to create combinations in demantra for future weeks and then the forecasters use the combinations to override the series and then release the orders from demantra. We use to series as future_row and then populate values via tmpl.

we insert the rows into t_src_sales_tmpl and execute the workflow to import the records into sales_data via workflow.

We are using the last_date as 1/1/1900 so the system is taking the last date loaded via sales tmpl as the history date. So after we run engine, the forecast values starts from a much later date in future. We want to understand if there is any way for us to indicate to the system that the rows are for future records and will not consider these records as history records.
