I have a SSIS package which calls a stored procedure to calculate taxes for a product. Now I need to change something. Whenever the product code starts with 'P' calculate 10% and 14 % tax for that product in pricing detail table. Whenever product code starts withj 'F' calculate 16% tax for that product. So in previous case there are two records created and in the later case there is just one record cretaed in the pricing detail table. How can I do it fast in my SSIS package or stored proc. used to create records in pricing detail table.?
