You cannot modify a quality if the quality is used in a production order, even if this production order is already woven. This is to ensure that you can check the used parameters of a finished product.
If you want to modify an existing quality, you can easily duplicate the current quality, modify some properties and save it as a new quality, so there is no need to re-enter all the parameters:
- Under Definitions (section SCHEDULING), open Quality related, then Quality.
- Select the quality and click the Duplicate button .
- After change the parameters, enter a new Name and click Save.
The duplicated quality is now available!
