Compute Phase Numbers (cprpd6200m000)

Use this session to recompute the phase numbers of plan items and plan units.

When Order Phase Number is selected in the Phase No. Type field, the order phase numbers are computed based on these product structures:

  • Bills of Material
  • Alternative Materials
  • Use-up Items
  • Subcontracting Bill of Material
  • Generic Bills of Material
  • Production Models for Repetitive Items
  • Subcontracting Models
  • Item / Derived-from Item relations
  • Supplying Relations

When Master Phase Number is selected in the Phase No. Type field, the master phase numbers are computed based on these product structures:

  • Planning Bill of Critical Material
  • Supplying Relations

The session checks for loops (cycles) in the product structures. Loops can be defined within one production structure table, but also the combination of all these different product structures can lead to loops.

The phase numbers of plan items are used by generating planned orders to plan the items in the correct sequence. Refer to Planning sequence and phase numbers.

Note: If the phase numbers of the items are not complete or correct, the Generate Order Planning process corrects the phase numbers of the items.

Field Information

Plan Level

The plan level of the plan items that are used as a starting point for the phase-number recomputation.

Phase No. Type

This field determines whether you recompute the phase numbers for master planning or order planning.

Step Size

The amount by which the phase number is increased when the computation procedure detects that the phase number is too low.

Default value

The default value is 5.

The computation of phase numbers is an iterative process. Initially, the phase numbers are set to zero. Then, the computation checks the plan items or plan units according to a certain procedure. Every time the computation detects a phase number which is too low, it increases the phase number by the step size.

Plan Unit

You can only define a range of plan units, if you selected Master Phase Number in the Phase No. Type field.

Multicompany Updating

If this check box is selected, LN performs a compute phase-numbers for all the plan companies of the multicompany scenario that you specify in the Scenario field.

Note: Refer to:
  • Multicompany planning
  • To recompute phase numbers
Scenario

The multicompany scenario of which the plan companies are taken into account for the recomputation of the phase numbers.

Allowed values

The scenario must be a multicompany scenario. A scenario is a multicompany scenario if the Central Multicompany Planning check box is selected in the Scenarios (cprpd4100m000) session.

Note: 
  • LN carries out the phase number computation for the plan companies of the scenario.
  • Multicompany planning
  • To recompute phase numbers
Stop at first Loop

If this check box is selected, the recomputation stops once a loop is discovered in a bill of material (BOM) of the selected item.

Error Report

If this check box is selected, LN generates a report.
