Following is the business scenario
Created STO intra company (Plant to Plant)
Created Outbound delivery, created Transfer orders and confirmed.
Created PGI by mistake.
Reversed PGI VL09, manually (LT01) transferred stock from 916 to 001 storage type for each material.
Reversed Outbound delivery
Now, I need to enter header condition but I am getting this error," You cannot enter new delivery costs."
Not sure it has something to do WM side or IM side.
