Negative APC control should not be changed (Check your entry)

What causes this issue?

You want to change the control for negative acquisition value.

System Response

This change is possible. It will effect all the assets you create in
this class in the future.
Assets already defined will not be effected by this change. If you want
them to be, you will have to perform a mass change for all the assets.
Instead of changing the control indicator for negative acquisition and
production costs, you should think about creating a new asset class.

How to fix this error?

Instead of changing the control indicator for negative APC, you
should consider creating a new asset class.
