| Product Variant Structures (tiapl3510m000) |  |
| Use this session to view and maintain product variant structures. A product variant structure defines the structure of a specific configured item by specifying the relations between this item and the generic items and engineering modules that make up this item. Generic sub-items can also have their own sub-items and/or engineering modules. The level below the engineering modules is specified in the flattened assembly parts, which appears in the Flattened Assembly Parts and Operations (tiapl2520m000) session. The product variant structure is created on the following moments: When the product variant is entered and saved, the product variant structure is created, in regard to the relation between the main item and the generic sub items. When you run the Generate Product Variant Structures (tiapl3210m000) ) session, the product variant structure is created, in regard to the relation between the main item and the engineering modules. Note, however, that this only happens if the External Product Variant Structure check box is cleared in the details of the Assembly Planning Parameters (tiapl0500m000) session. If required, the product variant structure can also be generated by the following sessions: Create Assembly Orders (tiapl3201m000) Refresh and Freeze Assembly Orders (tiapl3203m000) The generic items and engineering modules are retrieved from the following sources: The bill of material (BOM) relations to generic sub items are always copied from the item's template, which is defined in the Generic Bill of Material (tiapl2510m000) session. The BOM relations to engineering modules are either copied from the item's template, or delivered by an external source, which depends on the selection of the External Product Variant Structure check box in the Assembly Planning Parameters (tiapl0500m000) session. If this check box is selected, the BOM relations to engineering modules are delivered from an external source. ERP LN provides no functionality to copy the engineering modules from an external source to the product variant structure. If this check box is cleared, the BOM relations to engineering modules are copied from the item's template, which is defined in the Generic Bill of Material (tiapl2510m000) session. The information that is retrieved from the generic BOM is selected, based on the effectivity unit of the product variant, and the effective and expiry dates. The date range is evaluated against the Product Configuration Date, which is displayed in the details of the Product Variants (tiapl3500m000) session. You can only change the data in the current session if the following conditions apply: Your current company is defined as master company in the Assembly Planning Parameters (tiapl0500m000) session. You work in Test Mode, which is also defined in the Assembly Planning Parameters (tiapl0500m000) session. The Assembly Status, which appears in the Product Variants (tiapl3500m000) session, is Open. Product variant structures are deleted if the corresponding product variants are deleted. Refer to the To Be Deleted check box in the details of the Product Variants (tiapl3500m000) session, and to the Purge Product Variants (tiapl3200m000) session for more information.

Fields | Description
Product Variant | The code of the product variant for which the product variant structure is displayed.
Main Item | The generic main item that must be assembled. This item can be the end item, or a generic item between the end item and the engineering modules. The item must have the following characteristics: The item type must be Generic The item must be Serialized The item must have ordering data The item ordering system must be FAS These characteristics are defined in the Items - General (tcibd0501m000) session and the Items - Ordering (tcibd2500m000) session.
Position Number | The component's position number that identifies the combination of the main item and the sub item. By default, ERP LN shows the last position number used, plus 10. This procedure provides the sequence 10, 20, 30, and so on. The numbering of positions is unrestricted. It is recommended to use the default values so that you can use intermediate numbers to insert components.
Sub Item | The generic item or engineering module that is directly below the level of the displayed main item in the product variant structure.
Item Type | The item type of the sub item. The item type is either Generic or Engineering Module.
