Combining Strategies 10 and 30 
Prerequisites
You might want to create a new strategy group that combines the strategies Net Requirements Planning (10) and Production by Lot Size (30). This can be useful in the following situations:
- You have a few customers who demand relatively large quantities at the same time.
- There is relatively low demand from other customers and/or from internal customers, such as cost centers, which should be met using lot size optimization.

Procedure
To set up this strategy, proceed as follows:
- Combine strategy 10 with strategy 30 in the IMG for Demand Management under Planned Independent Requirements → Planning Strategy → Define strategy group.
- When defining the strategy group, use the planning strategy that you use most in your sales orders as the Main planning strategy.
- Maintain a material master with this new strategy group.
Result
You can now sell this material either way.
- If you maintain requirements type KL in the sales order, the process flow will be the same as for production by lot size (30).
- If you maintain requirements type KSL in the sales order, the process flow will be the same as for net requirements planning (10).
You can change the requirements type by selecting the Procurement type tab title in the sales order menu.
