This function classifies items based on their contribution to activity (ABC) as well as their turnover (abc). The combination sets the skip pattern: Aa, Ab, Ac, Ba, Bb, D365 BC, Ca, Cb, Cc. ## Steps To create or update a classification: 1. Choose the ![](https://cdn.document360.io/da662430-6a41-47b1-8c7e-7e4ac37a9756/Images/Documentation/image(149).png) icon (Alt+Q). 2. Type **Classification Worksheet** in the search box. 3. From the **Actions** menu, complete the following steps in this order: 1. [Set periods and classes](/business-central/docs/bc-run-item-classification#1-set-periods-and-classes) 2. [Set items to include](/business-central/docs/bc-run-item-classification#2-set-items-to-include) 3. [Calculate](/business-central/docs/bc-run-item-classification#3-calculate) 4. [Implement](/business-central/docs/bc-run-item-classification#4-implement) ### Set Periods and Classes Define parameters for each relevant business area. Set periods as a date formula so the calculation is based on rolling periods. #### Periods example: | Area | Start | Length | | --- | --- | --- | | Sales | -3Y | 3Y | | Production | -2Y | 2Y | | Project | -2Y | 2Y | | Transfer | -1Y | 1Y | | Assembly | -2Y | 2Y | In this example, sales are included for a period of three years starting three years in the past from the work date. Production, projects, and assembly demands for two years, and transfers (Ship) for one year. For activity as well as turnover, set a percentage for each of the classes. #### Classes example: | Type | Class A | Class B | Class C | | --- | --- | --- | --- | | Activity | 10 | 20 | 70 | | Turnover | 10 | 20 | 70 | In this example, when 10 (%) is specified for Class A, the items sorted from highest to lowest that make up 10% of the total value are assigned class A, the next 20% to B, and the remaining 70% to C. **ABC Statistics**: once calculated, the calculated values show in this section of the **Classification Setup** page. ### Set Items to include The classification for the item determines the skip pattern. Use this page to select items for which a classification must be calculated. With the **Update Item Selection** action, update the list using filters. The current item classifications are also shown on this page and are updated by the **Implement** action in the classification worksheet. The **Critical** field designates a quality-critical item for which skips are not allowed. ### Calculate Calculate the classification with the **Calculate** action, based on the periods and classes specified in the setup. The results show in the worksheet. For activity as well as turnover, three columns are shown: - **Actual**: retrieved from the **Set Items to include** page. - **Calculated**: the new calculated value. - **New**: same as calculated, but editable so you can update it. ### Implement After reviewing (and optionally correcting) the results, implement the new calculated value with the **Implement** action. This updates the values on the **Set Items to include** page. ## Related - [Quality Management](/bc-quality-management.md)
