| # To use up remaining stock of outdated items This topic introduces the concept of use-up materials. Often, new items are introduced that, in turn, make other items obsolete. The obsolete items are no longer deliverable or the items are no longer manufactured. If this type of item was used as material in a bill of material (BOM), you must replace the material by a replacement item with the same specifications. However, if you still have a quantity of the outdated material on stock, you want to use that first. The value of the Last allowed Order Date field in the Items - Ordering (tcibd2500m000) session determines when ERP Enterprise stops reordering the use-up material. To set the system up to use up the remaining quantity of the outdated item, you define that item as a use-up material in the BOM. Important! This functionality is available only if the Use Up and Alternative Materials check box in the Implemented Software Components (tccom0100s000) session is selected. Restrictions Use-up materials and alternative materials have the same net quantity as the standard material. Use-up materials and alternative materials have exactly the same values of characteristics such as the scrap and yield as the standard material. Use-up materials, alternative materials and the corresponding standard material can have different warehouses, but these warehouses must belong to the same cluster. Use-up materials and alternative materials have the same material-routing relationships as the standard item. If a component on a BOM line is a standard item, that is, an item with an empty project segment, the associated use-up and alternative materials must also be standard components. If a component on a BOM line is a project item, that is, an item with a filled project segment, the associated use-up and alternative materials' project segments must be either: Filled with the same project as the main item's project segment Empty (the alternative is a standard item) If a component on a BOM line is a phantom, you cannot define a use-up material or alternative material for that component. Checks for use-up materials At any of the following moments, depending on parameter settings, ERP Enterprise can check whether you must use any use-up material: When you generate planned production orders in the Enterprise Planning package. When the system generates a production order in the Shop Floor Control (SFC) module. When you release a production order. When you run the Generate Alternatives for Estimated Materials (ticst0216m000) session for existing production orders. When you generate an outbound advice in the Warehousing package. For more information, refer to The search for alternative materials. To use revisions and lot control instead of use-up materials If you use the Engineering Data Management (EDM) module to control changes in a bill of material (BOM) and you link subsequent revisions to the same item code on a BOM line, you cannot apply the use-up functionality. For that situation, you can apply lot control and use the FIFO outbound method. That outbound method ensures that you use up the outdated revision before you take the new revision.
