| Extended CTP checksExtended CTP checks are used to
explore the possibility of producing an extra quantity of an item, in addition
to the existing planning. Extended CTP checks come into play if the standard ATP of a plan item is
insufficient to cover a particular demand. In Enterprise Planning there are two types of extended CTP checks: You can enable or
disable these checks in the Items - Planning (cprpd1100m000) session. In the ATP Handling (cprrp4800m000) session, you can temporarily disable particular
checks. Note If multisite functionality is active, the checks are
performed per planning cluster. The component CTP check ignores the specification, regardless of the value of the Inherit Demand Peg field in the Bill of Material (tibom1110m000) session. LN simply presumes that all of the ATP of the components is
available.
Component CTP A component CTP
check for a plan item involves a full CTP check of the components of an item
for which you selected the Critical in CTP check box in the Items - Planning (cprpd1100m000) session. Depending on the
situation and on the item type, LN takes into account one of the following
bills to carry out component CTP checks: For each
CTP-critical component, a full CTP check is carried out. This check can consist
of various types of ATP and CTP checks, based on the settings in the Items - Planning (cprpd1100m000) session. Note that this can result in a multilevel
component check, in which LN checks lower-level components as well. Capacity CTP Combinations of checks Extended CTP checks are cumulative in nature: - For items, the
cumulative availability in a certain plan period (corrected for future
deficiencies) is checked.
- For resources, the
capacity up to and including a certain plan period (corrected for future
deficiencies) is checked.
Because of this
cumulative nature, some caution is called for when component and capacity
checks are both used for an item. If both checks succeed, this does not
necessarily mean that the availability of components and capacity will exactly
match in terms of time. After all, some of the available capacity can fall in a
plan period in which the necessary components are not yet available.
