My client is doing return sales order due to expiry of some material from its customer. When their Users process it by the system, System is picking up new VAT condition record 5%. The 5% VAT condition record was maintained on 12.07.2011 for Country/Plant/Region/Material Access Sequence but when they sent the material to customer it was on 18.04.2011 and that time 4% VAT was maintained for same sequence in the system, Invoice was also created as per the 4% VAT. During their return order processing System automatically pick up current delivery date and they put pricing date manually like 20.05.2011.
Question is why system is not considering previous record 4% as per the previous date 18.04.2011.
