what the change reason can be when calling oe_order_pub.Process_Line?

hi,

I am calling oe_order_pub.Process_Line to make a line cancel or ordered_quantity:=0.

l_rec.change_reason := 'Late Delivery'; --'Administrative Reason';

I have tried both of values 'Late Delivery' and 'Administrative Reason'.

but I have the following errors:

"message(2) = The reason for this change is either not provided or invalid. (OBJECT=ORDER LINE)

Error message: ORA-0000: normal, successful completion

Error code: 0

Stack:

"

"message(1) = Validation failed for the field - Change Reason

Error message: ORA-0000: normal, successful completion

Error code: 0

Stack:
