I have one problem in using the virtual attribute of the object type BUS2009 in Purchase Requisition(PR) Workflow . I have created a Virtual Attibute for getting Value of PR item . In the object type BUS2009 I have field for Quantity and Price but there is no field in the transparent table EBAN for Value of PR item . I can derive the value of PR item by multiplying the quantity and Price of an item which is already available in BUS2009.
So I have created virtual Attribute for Value of PR item and in the program of Object type Bus2009 I just made multiplication of quantity and rate of an item .
When I tried to display the virtual attribute value of PR item in the task I am getting only null value not the derived value from quantity and rate .
Can anyone help me out how to use the Virtual attribute in the object type BUS2009 and what are the steps to be followed in the program of Object type to get the calculated values other than database field values.
