Calculate Buffer Part Attributes

Explanation

This activity is used to calculate buffer part attributes. Buffer part attributes can be calculated for the selected part and for its top most parent parts as well. Once a part is set as a buffered part, it is necessary to assign relevant lead time categories, variability categories and the buffer zones. Once the part is set to buffered part, it decouples the lead time of the parent parts due to the change of the existing lead time of the parent. Other buffer part attributes also gets affected with this change. Calculation can also be extended to parent parts and to get that benefit as well. 

Note: variability is measured during the rolling time horizon for historical ADU, which is determined by the lead time category for the part. If this time horizon is longer than the time with issue transactions for the part, you should set the variability category manually, since the measured variability will be unrealistically high.

Prerequisites

Part should be defined as buffered part.

System Effects

• Unprotected lead time of the relevant part and optionally its parent parts will be calculated.
• Historical ADU, ADU alerts will be calculated.
• Coefficient of variability is calculated and variability category gets assigned for parts with automatic update of varability category.
• ADU alert message will be created by evaluating the conditions.
• Buffer zones will be calculated for the part and optionally its parent parts.

4. Click OK.

From the Inventory Part window:

1. Select the part for which you want to calculate buffer part attributes.
2. In the Inventory Part/Planning Data/Buffer Part Attributes tab, right-click and then click Calculate Buffer Part Attribute.
3. Select Yes if you want to perform the calculation for the part and its parent. Select No to only calculate attributes for the relevant part.
4. Click OK.

From the Buffer Parts Attributes window:

1. Search for the part for which you want to calculate buffer part attributes.
2. Right-click and then click Calculate Buffer Part Attributes.
3. Select Yes if you want to perform the calculation for the part and its parent. Select No to only calculate attributes for the relevant part.
4. Click OK.

From the Calculate Buffer Part Attributes dialog box:

1. Enter Site and the Part Number for which you want to calculate attributes.
2. Click OK.
