Consumption across Forecast Sets
Consumption can occur multiple times if an item appears in more than
one forecast set. For example:
Figure 2 – 3
CONSUMPTION ACROSS FORECAST SETS
Forecast Set #1
Forecast #1
Item A
Item B
Forecast Set #2
Forecast #2
Item A
Item C
Forecast Set #1 contains Forecast #1 and Forecast Set #2 contains
Forecast #2. The same item, Item A, belongs to both forecasts within
each set.
When you create a sales order, both forecasts for Item A in Forecast Set
#1 and Forecast Set #2 are consumed. This is because consumption
occurs against each forecast set, and Item A exists in both forecast sets.
For example, if each forecast for Item A is quantity 100 and you place
sales order demand for 20, the consumption process would decrement
each forecast in each set from 100 to 80.
Note: In this example, Forecast Set #1 and Forecast Set #2 are
most likely alternative scenarios — two different sets for
comparison purposes, so that consumption occurs for the same
item in both sets. If you want to consume an item only once,
define all forecasts for an item within a single set. See:
Figure 2 – 1.
