Have a clarification on whether scenario can be achieved using FP:

 

If yes, can we have the details of how to go about same.

 

 

1.       Need to have User item description defaulted as Item description from item master based on item number at the SO line level. This is achieved by When_Validate_Record.

 

2.       Need to have the ability given to user to change the User item description after above default. This is achieved by When_Validate_Record and also giving the condition as apply the FP on null value only.

 

3.       Now with the above, when the item is changed to a new item (By substitution or when copy the order and changing item), the default does not happen again. How to achieve the same?
