| | Check Horizons (cprpd1200m000)Use this session to update (full) cumulative
order lead times, and to compute the minimum length of order horizons and planning horizons in the Items - Planning (cprpd1100m000) session for a range of plan items. The calculations are based on: - Cumulative order lead
times
- Synchronization
between order horizons at various BOM levels
In the Items - Planning (cprpd1100m000) session, select the Automate Update Horizons check box for the items whose order horizon and planning horizon must be
updated. In the Update Method field,
you can choose these update methods: COLT Creates a report on the order horizons and planning horizons
that are too small, but does not actually update these horizons. COLT + Horizons When Too Small Updates the order horizons and planning horizons that are too
small COLT + All Horizons Updates all order horizons and planning horizons, resetting
them to their minimum levels
Regardless of the method you choose, in the Items - Planning (cprpd1100m000) session, these COLT values are always
updated: - COLT
- Non-Critical COLT
- Full Cumulative Order Lead Time
- Full Non-Critical COLT
Note The COLT calculation also takes into account the values
that you specify in the following fields: - Additional Lead Time
- Order Lead-Time Multiplier
From Plan Item An item with the order system Planned. The production, distribution, or purchase of these items is
planned in Enterprise Planning based on the forecast or the actual demand. You can plan these items by means of the following: - Master-based planning, which is similar to master production
scheduling techniques.
- Order-based planning, which is similar to
material-requirements planning techniques.
- A combination of master-based planning and order-based
planning.
Plan items can be one of the following: - An actual manufactured or purchased item.
- A product family.
- A basic model, that is, a defined product variant of a
generic item.
A group of similar plan items or families is called a product
family. The items are aggregated to give a more general plan than the one
devised for individual items. A code displayed by the item code's cluster
segment shows that the plan item is a clustered item that is used for
distribution planning. Planner The employee or department responsible for planning the
production, purchase and distribution of items. The planner takes into account
the inventory levels, availability of materials, and capacities of resources,
and reacts on signals such as rescheduling messages that LN generates. Order Lead-Time Multiplier The multiplier that is applied to the minimum order horizon and
minimum planning horizon to determine the actual order horizon and actual
planning horizon. Adjustment of the actual horizons depends on the selected Update Method. Include Parent Items If this check box is selected, the item selection is
extended with the parent items of the items in the selection range
(multi-level). Note The following restrictions apply: - The plan level of the items involved must fall within the
selected range of plan levels.
- LN simulates only
parent items with an anonymous order policy. Items with an anonymous order
policy have item codes with an empty project segment.
Include Child Items If this check box is selected, the item selection is
extended with the components of the items in the selection range (multi-level). Note The following restrictions apply: - The plan level of the items involved must fall within the
selected range of plan levels.
- LN simulates only
child items with an anonymous order policy. Items with an anonymous order
policy have item codes with an empty project segment.
Print Warnings If this check box is selected, besides the standard
error report, a warning report is generated. The warning report
contains warnings for parent items included in the selected range of plan items
for which LN was unable to check the horizons, because their phase number is lower than that
of the child item. Update Method Select one of the update methods from the pull-down menu. Regardless of the method you choose, in the Items - Planning (cprpd1100m000) session, these COLT values are always
updated: - COLT
- Non-Critical COLT
- Full Cumulative Order Lead Time
- Full Non-Critical COLT
In the Items - Planning (cprpd1100m000) session, you must select the Automate Update Horizons check box for the items for which you want LN to update
the order horizon and the planning horizon. The difference between the three update methods is: COLT Creates a report on the order horizons and planning
horizons that are too small, but does not actually update these horizons. COLT + Horizons When Too Small Updates the order horizons and planning horizons that are
too small. COLT + All Horizons Updates all order horizons and planning horizons, resetting
them to their minimum levels.
