How to fix this error?

If you still want to define hierarchy field &V1& as a characteristic,
proceed as follows:
Display the where-used list for data element &V2& in database fields
using transaction SE12. <ZH>For hierarchy field &V1& to be adapted, a
data conversion must be carried out for all the tables listed!</>
First change the number of characters in the domain &V3& to match the
new definition of the product hierarchy, following the example below.
You can do this using transaction SE11.

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