The flushing method is copied to this field from the Flushing Method field on the item card, but you can change it on the production order component line.

For more information, see the Flushing Method field on the tem card.

If you use bin codes to pick components, then the flushing method affects the value in the Bin Code field on the production order component line.

Note
Because the bin code on production order component lines is partly defined by the flushing method of the component, the values in the two fields can change interdependently, or you may see warnings when you change a bin code or flushing method on the line.
