* The flushing principle is a setting that determines how and when the raw materials are consumed from inventory and registered as work in progress (WIP) for production orders and batch orders1. The flushing principle can be configured at the product level, the bill of materials (BOM) or formula line level, or the production order or batch order line level1.
* The Start flushing principle indicates that the material will be automatically consumed when the production order is started1. The amount of material that is consumed is proportional to the quantity that is started. This principle is relevant if, for example, the variance in the consumption is low, the materials are low-value materials, there are no tracking requirements, or there's a short run time on operations1.
* In this scenario, the warehouse manager requires that products are removed from on-hand inventory and consumed when they are picked and staged for production. Therefore, the Start flushing principle should be configured for the batch-tracked products. This way, the products will be deducted from inventory and set to WIP as soon as the production order is started on the hand-held device.
