BL20 - Unit Price Default

Hello!

Could someone throw some information on the below?

I created an Item in IC system and tried using the item in BL20.1 Invoice entry. I did create price list for this item in BL40.1

But when i tried to add an invoice for this item in BL20.1, the unit price doesnot default.

Please let me know if i have missed any other steps or setup information on the above

Thanks
Kamal
