4 Size Range Management

The Size Range Management workbook is used to set the kink inner neighboring ratio, the kink outer neighboring ratio, and the expected kink sizes.

Note: Refer to the Kinks and Kink Exceptions for details on kinks and how they are handled by SPO.

The Size Range Management task contains the following steps:

• Kink Exception Step

• Sub-Size Range Management Step

Size Range Management Workbook Wizard

To build the Size Range Management workbook, perform the following steps:

1. Click the Create New Workbook icon in the Size Range Management task.

   You may be prompted to select a domain if you have access to more than one domain. For information on domain selection, see "Selecting the Domain when Creating a New Workbook" in Chapter 2.

2. The workbook wizard opens at the Select Style/Color screen. Select the style/color you would like to examine, and click Next.

3. The stores are displayed on the Select Store workbook wizard. Choose the locations, and click Next.

The Size Range Management workbook is built.

Kink Exception Step

The Kink Exception step allows users to specify kink sizes as well as kink ratios for detecting kink exceptions.

The following sections describe the views available in the Kink Exception step:

• Kink Sizes View

• Kink Ratio View

Kink Sizes View

The Kink Sizes view contains a Boolean measure called Expected Kink Sizes, which indicates whether or not a size is odd. The intersection for this view is at the size level.

Figure 4-5 Kink Sizes View

The following table describes the measures available on this view.

Table 4-1 Kink Sizes View Measures

Measure	Description
Expected Kink Sizes	Indicates whether or not a size is odd.

Kink Ratio View

The Kink Ratios view allows users to specify parameters that are used by the system for detecting kinks in size profiles. Note that if a size is identified by a user as an odd size, the system does not test that size for kinks.

The systems checks for or attempts to detect kinks by comparing sizes in a size range to their neighbors. The comparison is done by computing the ratio of the size to its inner and outer neighbors.

If a neighboring size is closer to the middle of the size range than the examined size, then the neighboring size is considered an inner neighbor. For example, in a size range with five sizes, size 3 is considered an inner neighbor of size 2. Size 1 is considered an outer neighbor of size 2.

The inner and outer ratios of a size are defined as a profile of its inner neighbor divided by the profile of the examined size, and the profile of its outer neighbor divided by the profile of the examined size respectively. Note that these ratios do not exist for border sizes.

The system computes the inner and outer ratios of a size and checks to see if both the ratios exceed the thresholds specified. Note that both the thresholds need to be exceeded for a size to be considered a kink.

The Kink Ratio view displays the inner kink ratio and the outer kink ratio. The intersection for this view is at the size range level.

Figure 4-6 Kink Ratio View

The following table describes the measures available on this view.

Table 4-2 Kink Ratio View Measures

Measure	Description
Kink Inner Ratio	The threshold for the inner ratio (see above for definition of inner ratio). If the inner and outer ratios of a size exceed the kink inner and kink outer ratios specified, the system considers the size a kink.
Kink Outer Ratio	The threshold for the outer ratio (see above for definition of inner ratio). If the inner and outer ratios of a size exceed the kink inner and kink outer ratios specified, the system considers the size a kink.

Sub-Size Range Management Step

The Sub-Size Range Management step allows users to specify the size ranges for which the SPO batch should generate size profiles.

The following sections describe the views available under the Size Range Management step:

• Manage Sub-Size Range Assignment View

• Sub-Size Range Assignment Validation View

Manage Sub-Size Range Assignment View

The Manage Sub-Size Range Assignment view contains the selected stores and size ranges available. Select the check box to specify that a new size profile run needs to be executed for the selected store.

This view shows which of the subsize ranges is assigned to each store for the selected merchandise. In this example, the first two stores are assigned to one sub size range and the third store is assigned to a different sub size range.

Figure 4-7 Manage Sub-Size Range Assignment View

The following table describes the measures available on this view.

Table 4-3 Manage Sub-Size Range Assignment View Measures

Measure	Description
Sub-size Range Assignment	Select the check box to assign a sub-size range to each SKU parent/store.

Sub-Size Range Assignment Validation View

The Sub-Size Range Assignment Validation view is used to display the stores for which valid size ranges are available. This view is used to ensure that each of the stores is mapped to one of the available sub-size ranges.

Figure 4-8 Sub-Size Range Assignment Validation

The following table describes the measures available on this view.

Table 4-4 Sub-Size Range Assignment Validation Measures

Measure	Description
SKU Parent/Store to Sub-size Range Validation	This is a calculated measure. When true, one sub-size range is assigned to a SKU parent/store.
