Forward, manual, and backward flushing are terms related to inventory management in Microsoft Dynamics 365 Business Central, particularly around how materials are consumed in production:
1. Forward Flushing: Automatically deducts the materials expected to be used as soon as a production order is released. This is typically set for items where consumption is predictable and consistent.
2. Manual Flushing: This requires the user to manually indicate when materials are consumed during or after production. It's used when you need precise control over material usage.
3. Backward Flushing: Automatically deducts materials after the production output is posted, based on what should have been used according to the bill of materials. This method assumes that the actual consumption matches the planned consumption.
Each method has its use cases depending on the level of control and automation a business needs in its production process.
