ITEM and UOM not on PRICE LIST

 Hi All,

We have defined an Pricing Attribute to Default Selling Price.

After defining a pricing attribute its linked to items under price list. The scenario works as expected.

But every time when i enter the item in a Sales Order line am getting a note message as 'X Item and Y Uom is not in Z Price List' 

Is anywhere am missing a setup??

I have run Build Attribute mapping rules program too. Still this message appears

Please help

Thanks
