Can you help me in service mapping.
Requirement of client is that they want a different pricing based on ship to site. For that i am defining Pricing Strategy based on Ship to site Postal code. I added ship to site Postal code Column at Strategy assignment level. But no strategy is defaulting on sales order. Other setups are correct because i am using similar setup for Pricing Based on Ship to site ID.
Thanks in advance
