Condition type getting deleted
When we create sales order for configurable material and upload the configuraion the Bom material , pricing is showing in condition TAB Condition type is z created. BUt if we do further process the sales order such as if we tick the frieght checkbox,the pricing of one material is disappearing in condition TAB.But if when we check the variant in VK13 for same material it is there.
please anybody have any clue wy pricing is getting deleted from condition TAB for one material only.
Thanks and Regards
