Every year mass change on the prices creating bottle neck and risk if it is done by SQL script to update the DB.
Project Price Change : Pricing Plant is the one for each product. However the products are mostly setup with # (all) option. In this case, there is no way separating some projects with pricing plants (in pricing tab). That usually may separate the specific area. Now that Region is added as feature. If PROJECT PRICING PLANT's (NOT Project Product Pricing Plant) Region could be selected; it can easily separate the different area. That would save a lot of time for IT taken care of mass price change, less risky and user will benefited using this fine tool. Top of that; Salesman filter could also be helpful.
