What causes this issue?

At a later stage within this enhancement workbench, you might have to
enhance an SAP object. Technically speaking you might have to create a
DDIC object, such as an append structure. This DDIC object has to be
within the customer namespace and can therefore only be created as part
of a local, private, or customer package.
The selected package &1 does not belong to the local, private, or
customer namespace.

System Response

The system does not accept the package.

How to fix this error?

If you do not have to create DDIC objects, you can leave this field
empty.
If you are unsure, you can keep the local package $TMP and check what
happens in the later steps.
If you know that you have to create new DDIC objects, choose an
appropriate package as follows:
Type,,First character
Local,,$
Private,,T
Customer,,Y or Z
