We have a generic account. Which has say 3 ship to. we have attached price list A to to 1st ship to, price list B to the 2nd ship to and price list C to the 3rd ship to.

Isuue is: to search and order skus we need to have a price list at the account level. If i add price list A at the customer account level. The users who are suppose to use price list B and C will see only items in price list A as currently price list A is attached at Customer Account level.

So each time price list B customers has to use this generic account to order, we had to change the price list at the customer account level to B

and each time price list C customers has to use this generic account to order, we had to change the price list at the customer account level to C

Is there any solution to such generic accounts.?

Please help

Thanks in Advance.
