Set Pricing context and Pricing attribute using Quoting user hook

 Hi,

I want to set the pricing context and pricing attributes for items added to iStore cart. I tried assigning the values using a quoting user hook. In ASO_QUOTE_CUHK.crate_quote_pre, I assigned the line pricing context as follows:

       

        p_ln_price_attributes_tbl(1).PRICING_CONTEXT := 'CUSTOM_CONTEXT';

        p_ln_price_attributes_tbl(1).PRICING_ATTRIBUTE1 := 'x';

        p_ln_price_attributes_tbl(1).PRICING_ATTRIBUTE2 := 'y';

        p_ln_price_attributes_tbl(1).PRICING_ATTRIBUTE3 := 'z';

This does not set the pricing attributes. I was expecting this to create an entry in aso_price_attributes table, but this does not happen.
