| To change an item's default data |  |
| You can change an item's default data by selecting a different item type or item group, or both, for the item. You can do this only if the item is not yet in use. If you change the item type/item group combination of an item, the following message appears:
    Item type/item group combination has changed. Re-read default item data
    for the new combination and delete existing sub-entities?
If you click Yes, ERP LN deletes all existing sub-entities of the item and creates new sub-entities according to the new default values of the item type/item group combination defined in the Items - General Defaults (tcibd0502m000) session. Note that if the item production data is deleted, the BOM and routing are deleted as well. If you click No, no sub-entity will be deleted and no new sub-entities will be created. The item's sub-entities consist of the item data that is specific for the ERP LN packages. For example, item sub-entities are the item sales data, the item production data, and the item warehousing data. ERP LN uses the selected check boxes of the Implemented Software Components (tccom0100s000) session to detect whether item sub-entity data can exist. For example, if the Warehousing check box is cleared in the Implemented Software Components (tccom0100s000) session, ERP LN does not delete item warehousing data or create new item warehousing data. Note If inventory of an item exists and you change the item group, for example, to perform cost price calculation, ERP LN cannot apply the new default values to the item's inventory. The item keeps the default data of the previous item group, such as: The unit set. The inventory unit. The lot control selection. The product type. ERP LN does not delete or create item sub-entities for Project items of the types: Equipment. Subcontracted Service. You can define, change, and delete Equipment items only in the Standard Equipment (tppdm0512m000) session and the Project Equipment (tppdm6512m000) session of Project. If you entered a Subcontracted Service item in the Standard Subcontracting (tppdm0513m000) session or the Project Subcontracting (tppdm6513m000) session of Project, you cannot change the item group in the Item - General (tcibd0101s000) session. ERP LN deletes the data when you save the changed item type/item group data. If you exit the session and do not save the changed data, ERP LN does not change or delete any item data or item sub-entity data. Related topics To set up the item data |
