Planning Variants w/ a Planning Material (65) 
This strategy is similar to
Planning w/ a Planning Material (60). The difference between these two strategies is that strategy 65 allows the user to reconfigure the variant during a sales order.
Changes to the configuration must not affect planned components. Planned independent requirements for variants do not make sense when changing the configuration of the variant in the sales order. A sold item that has no relation to the configuration of the planned variant could result. Therefore, change the configuration for strategy 65 with care.
Prerequisites
You must maintain the following master data settings:
Process Flow
You create one planned independent requirement per variant. The variant must be completely configured.
Components of the variants are procured.
You create sales orders either directly, by entering a variant, or by entering a configurable material and using variant determination. The Requirements Type display for strategy 65 is ELVV. To display the requirement type from the Sales Order screen, choose Procurement tab strip.
Make-to-Order production (assembly) of the finished product takes place.
The finished product is delivered.
