This feature adds a parameter called "Replace alternative item defaults on sales lines" to the "General" tab of the "Accounts Receivable parameters" page. When this parameter is set to "Yes", and alternative items must always be used, all item-dependent information (such as financial dimensions and units of measure) from the alternative item will replace the original item information on the sales order line. When set to "No", all the information from the original item will remain on the sales order line and no replacements will be made. When you first enable this feature, the parameter defaults to "Yes", which matches the way the system behaves without this feature.
