THe parameter "MAX enforced' on the Agreement line is by default 'NO" I do not know any customers who want to let the remaining quantity on the Agreement line go negative but there could be customers like that. It is much more logical to me to make this parameter say "YES" as a default. Or better still: let the user choose in a new parameter in Procurement. What is your default for MAX enforced? Yes/No. With that it should also be allowed to change it from No to Yes later when you still have plenty of remaining quantity. Right now this is not allowed I wonder why we don't allow that. Of course when we have gone over MAX already, the field should be locked.
