Creating and maintaining a Price List by Customer’s Part#

Summary:

Please let me know if you have used or created any extension for the following 2 requirements

Content (required):

1)          Creating and maintaining a Price List by Customer’s Part# - I can setup an Item Cross Reference in PIM, key in the customer part number in the Item number field and the system will return the PTC Item number, however the table doesn’t retain the Customer Part Number for future updates.

2)          Price List Setup - The maintenance for creating Customer Specific and Site Specific Pricing can be cumbersome. I believe the Mass Price Update should be fine for changes to Price List but do not know if the mass price list can be enhanced or extended to mass update customer specific or site specific pricing updates.
