Manual

Requires that you manually enter and post consumption in the consumption journal.

Forward

Automatically posts consumption according to the production order component lines.

By default, the posting of component consumption occurs when you change the status of a production order to Released. However, if you use the Routing Link Code field on production order component lines, then posting occurs per operation when the operation starts. For more information, see How to: Create Routing Links.

Note
For forward flushing, the operation-specific posting that you obtain with routing link codes is based on the expected quantity that is defined on the component line. For information about operation-specific flushing based on actual output, see the description of Backward in this topic.

If the location or resources where this component is consumed are set up with a default bin structure, then the item is consumed from the open shop floor bin. For more information, see How to: Set Up Basic Warehouses with Operations Areas.

Caution

Forward flushing also occurs when you click Refresh on a released production order that was created from scratch. On these directly created released production orders, you cannot change bin information because the production order component lines are generated when you refresh the order, which at the same time forward flushes the components. Therefore, if you want to change bin information on production order component lines before forward flushing occurs, then that order must be created with the Planned or Firm Planned status.

Backward

Automatically calculates and posts consumption according to the production order component lines.

By default, the calculation and posting of component consumption occurs when you change the status of a released production order to Finished. However, if you use the Routing Link Code field on the production order component lines, then calculation and posting occurs when each operation is finished.

Note
Backward flushing and routing link codes can be combined so that the quantity that is flushed per operation is proportional to the actual output of that operation. For more information, see How to: Flush Components According to Operation Output.

If the location or resources where this component is consumed are set up with a default bin structure, then the item is consumed from the open shop floor bin.

Pick + Forward

Same as for Forward flushing method, except it only works for locations that use directed put-away and pick.

Consumption is calculated and posted from the bin that is defined in the To-Production Bin Code field on the location or machine center after the component has been picked from the warehouse.

Note
If a component is set up with the Pick + Forward flushing method, then it cannot have a routing link code to an operation that is set up with the forward flushing method. The component would then be automatically flushed when the operation starts, which makes it impossible to request the pick activity.

Pick + Backward

Same as for Backward flushing method, except it only works for locations that use directed put-away and pick.

Consumption is calculated and posted from the bin that is defined in the To-Production Bin Code field on the location or machine center after the component has been picked from the warehouse.
