+/**\r
+ Sets the SKU value for subsequent calls to set or get PCD token values.\r
+\r
+ SetSku() sets the SKU Id to be used for subsequent calls to set or get PCD values. \r
+ SetSku() is normally called only once by the system.\r
+\r
+ For each item (token), the database can hold a single value that applies to all SKUs, \r
+ or multiple values, where each value is associated with a specific SKU Id. Items with multiple, \r
+ SKU-specific values are called SKU enabled. \r
+ \r
+ The SKU Id of zero is reserved as a default. The valid SkuId range is 1 to 255. \r
+ For tokens that are not SKU enabled, the system ignores any set SKU Id and works with the \r
+ single value for that token. For SKU-enabled tokens, the system will use the SKU Id set by the \r
+ last call to SetSku(). If no SKU Id is set or the currently set SKU Id isn't valid for the specified token, \r
+ the system uses the default SKU Id. If the system attempts to use the default SKU Id and no value has been \r
+ set for that Id, the results are unpredictable.\r
+\r
+ @param[in] SkuId The SKU value that will be used when the PCD service will retrieve and \r
+ set values associated with a PCD token.\r
