A cost entry’s detail page shows three tabs: Overview, Positions, and
Billing Periods. Amounts, quantities, and terms hang exclusively on the
positions — the entry itself carries none.
List of Cost Entries
The list always refers to the current month; there is no period selection
here. The Status column shows the status that follows from the terms of
the positions. Delete is the only bulk action — editing happens only on the
detail page.
For earlier months, switch to the Billing Periods tab on the cost entry —
each period is listed separately, see
Assigning Costs to Assets. Overview
Four figures relate to the current month: Monthly Costs, Total Volume
(amount across the whole term), Utilization (assigned of assignable
units), and Unused / Month. Without positions, all four show a dash.
Contract Number and Responsible can be edited here directly. The
Supplier, however, sits on the individual position, not here — a framework
contract can bundle services from different suppliers.
Reading Positions
Two columns diverge from the expected value in special cases:
- Billing Cycle shows Overhead instead of a billing rhythm for positions
that cannot be assigned.
- Monthly Cost shows a dash when a one-off position has no useful life —
the amount itself is still recorded.
Changeable Fields of a Position
Edit opens only a small part of the fields:
Cost type, category, billing cycle, start date, unit price, quantity, useful
life, document numbers, and unit cannot be changed afterwards. A typo in the
unit price or a quantity entered too low cannot be corrected through Edit.
An end date already set can only be moved further out through Edit, never
brought forward. For a shorter term, the only route is Duplicate — this
block does not apply to the copy.
If a contract grows, an additional position through the Position button
remains an alternative to the copy: it carries its own start date, while the
existing position and its assignments stay untouched.
Consequences of a Change
Positions determine the status and term of the cost entry and generate the
monthly billing periods. Every creation, edit, duplication, and deletion
rebuilds both.
Because billing periods come from the positions, Delete also affects their
periods — including months already assigned. An expired contract does not
need to be deleted: it counts as expired once its end date has passed.
Deleting several positions at once can partly fail: those already deleted
stay deleted, and the message names the remaining positions.
