Only show valid part lines

If this setting is enabled, the form only lists the calculation lines for which the reference date falls within the validity range of the relevant calculation lines. The reference date depends on the revision setting specified on the Revision management tab of the Basic data form:

If you are using reference dates, the reference date is the current date.
If you are using revision numbers, the reference date is the start date of the revision.

If the setting is not enabled, all calculation lines are displayed.
