Hi,
I happen to support one client that when I simply create SO line and input item number, the system defaults value in 'Return cost price' field.

But when I check in application of another client by creating SO line and inputting item number, it doesn't have the value default to this field.
Can anyone tell me what is 'Return cost price' field in SO lines for, where is the value from and how to have the value defaulted?
The only time I have seen this field defaulted is when using create credit note function then system will input 'Return lot ID' and 'Return cost price' fields. Apart from this I haven't seen this field with value.
Thank you so much,
Kullarat
