Planning w/o Final Assembly at Assembly Level (74) 
Purpose
This planning strategy is particularly useful for manufacturers of products with variants if a more reliable forecast can be produced for certain assemblies than for the multitude of product variants.
Prerequisites
You must maintain the master data at the assembly level as follows:
- Strategy group 74 on the MRP screen.
- Set the indicator for assembly planning, the Mixed MRP indicator, to 3 on the MRP screen.
- Consumption parameters (Consumption mode, Bwd consumption, Fwd consumption on the MRP screen) to allow for consumption of planned independent requirements.
- If you are using this strategy in a make-to-stock environment, you also must set the Individual/coll. indicator to 2 on the MRP screen.
You must maintain the master data for the component of the assembly as follows:
- Set the Individual/coll. indicator to 2 on the MRP screen.
You must maintain a BOM for the assembly and its components.
Process Flow
For a detailed example of the entire process, see
Sample Scenario 74.This strategy is very similar to
Planning w/o Final Assembly (50) and
Planning w/o Final Assembly and w/o MTO (52). However, planned independent requirements are consumed by production order requirements (or schedule lines in repetitive manufacturing) and not to requirements of sales orders. This strategy should be used in the following business context:
- Stock for the assembly should not exist.
- Planned independent requirements are entered at assembly level. Procurement (planned by means of the planned independent requirements) is therefore triggered before the production order stage (or schedule line in repetitive manufacturing).
- The planned orders for the assembly/components are not convertible.
- Requirements from production orders (or schedule lines) are passed on to production and can lead to changes to procurement after the sales order stage, if the order quantities exceed the planned independent requirement quantities. However the order quantities cannot be confirmed if there is insufficient coverage of components. The system automatically adjusts the master plan. For more information see
Coping with Insufficient Coverage of Components.
The planned independent requirements are consumed during the production stage. This means that you can compare the planned independent requirements situation with the actual order requirements.
