Transferring Product Group Proportions in Standard SOP 
If you are disaggregating a product group plan in standard SOP (Disaggregation → Break down product group plan), you can create sales plans for product group members as proportions of the owner product group’s sales or production plan. The system calculates these proportions using the proportional factors in the product group’s master record.
To transfer product group proportions:
- In the planning table (split screen), choose Edit → Create sales plan → Transfer PG proportion → PG: production or PG: sales.
The calculated sales quantities appear in the bottom half of the screen.
