A database field with the same name but different data type
specification was already enabled for use in the app <ZK>Custom Fields
and Logic</> as custom field <(>&<)>1.

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?

If you want to enable the current database field as well, it needs to be
attached to the already existing custom field <(>&<)>1, thus making the
custom field available in another business context.
This requires that the data element of the already enabled field can
also be used for your current database field without data loss. Please
refer to the ABAP Dictionary documentation in order to check whether
this requirement can be fulfilled.
If so, press <ZK>Prepare</> and follow the step-by-step instructions
given there.
