Actually, in the above screenshot which i have shared..if the MAT_NUM = "SCHEME" or "VAS", doesnt have DeliveryOrderNo.. Here DeliveryOrderNo is a primary key.
Could any one plz suggest me that the When if the MAT_NUM = "SCHEME" or "VAS", there will not be any DeliveryOrderNo.
So, what changes could be made that values should pass as "X" in DeliveryOrderNo when the values coming for MAT_NUM = "SCHEME" or "VAS".
