| # To define alternative materials This topic describes several sessions you can use to define alternative materials for materials in bills of material (BOMs). Note This functionality is available only if the Use Up and Alternative Materials check box is selected in the Implemented Software Components (tccom0100s000) session. Alternative materials in BOMs To define alternative materials in BOMs, you can use the following procedure: Start the Bill of Material (tibom1110m000) session, go to the relevant BOM, and double-click the BOM line to start the details session. If you want to permit more than one item to be used for one material requirement, on the Validity tab, select the Allow Multiple Items check box. Click Use Up and Alternative Materials. Insert the alternative materials in the Use Up and Alternative Materials (tibom0150m000) session. Batch-wise definition of alternative materials To define alternative materials for multiple BOMs at once, use the Copy Item to Alternative Materials (tibom0250m000) session. Alternative materials in Engineering BOMs (EBOM) To define alternative materials in EBOMs, take the following steps: Start the Engineering BOM (tiedm1110m000) session, go to the relevant EBOM and double-click the BOM line to start the details session. If you want to permit more than one item to be used for one material requirement, select the Allow Multiple Items check box. Click Use Up and Alternative Materials by Engineering BOM. Insert the alternative materials in the Use Up and Alternative Materials by Engineering BOM (tiedm2115m000) session. You can copy the EBOM with the EBOM's alternative materials to a production BOM. For more information, refer to the Engineering BOMs topic.
