The L.S.A. Data is used to define Logistic Support Analysis and product Maintenance Data. This includes mapping of BOM-items to specific repair or maintenance operations, repair scrap- and failure allocation percentages and identification of Illustrated parts catalogues. Via this tab an item-link is also identified as the item being consumed or utilized only and whether it is a standard- or "as needed" replacement when the parent part is maintained. It also provides settings to specify whether extra material (for spillage, chuck allowance and others) or QA pieces (to demonstrate that manufacturing processes are under control by manufacturing additional pieces for QA purposes) are required (also see tab "QA and extra pieces").
