Field & was not copied

What causes this issue?

The field &v1& was not copied to the open hub destination. This field
has a fixed unit or currency in the template.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

You can manually copy the field to the open hub destination. Enter it in
the field list with the correct field properties. In the field list,
also enter the unit or currency field to which the field refers. This
field must be filled by the transformation.
The structure of the open hub destination assumes that all the unit
fields are also in the structure and are filled at runtime to ensure a
consistent external view on the data.
