Planning at Assembly Level (70) 
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 of the assembly as follows:
- Strategy group 70 on the MRP screen.
- Set the indicator for assembly planning, the Mixed MRP indicator, to 1 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.
Process Flow
For a detailed example of the entire process, see
Sample Scenario: Strategy 70.This strategy is very similar to
Planning with Final Assembly (40). However, planned independent requirements are consumed by production order requirements (or schedule lines in repetitive manufacturing) and not to requirements of sales orders. Although all graphics in this documentation show this component one level below the finished product, the component can appear on any BOM level.- Stock for the assembly usually exists.
- 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 convertible.
- Procurement smoothing according to order demand is possible. In this strategy, however, the ability to react flexibly to customer requirements is more important.
- An accurate availability check is performed according to ATP logic during production order processing. See
Availability Check.
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.
Unconsumed planned independent requirement quantities increase the warehouse stock of the component, and cause procurement to be decreased or not to take place at all in the next period. This procedure is called "netting."
