When adding a part to an underlying part calculation line, some of the fields are copied from the part. For most of those fields, any changes to the part made on the Parts form do not affect the part calculation. The Change calculation lines process allows you to change data on all calculations lines on which the part occurs at the same time.
Conditions
Changes to part calculation lines are not applied if:
If you select the Order code check box and then select an order code, all part calculations will be searched for the specified part with this order code. This code will be replaced by the new order code.
Select the Description check box if you have changed the description of a part on the Parts form and you want to apply this change to any part calculations containing the part.
If you select the Phantom check box, you can choose to enable or disable the Show phantom option for all part calculation lines containing the specified part.
