Message text: At least one table for object &1 has no cust. delivery class
At least one table in the logical transport object (type 'L') &V1& has
an inappropriate delivery class for customizing data, or is a system
object (e.g. table T000, TADIR, CVERS, ....).
The tables must not be system objects, and must have one of the
following delivery classes (transaction SE11) to be able to be used in
BC Sets:
'C': customizing table, maintained by customer, not an SAP import
'G': customizing table, protected against SAP UPD, only INS allowed
'E': control table, SAP and customer have their own key areas
SPACE: is also accepted as customizing delivery class
<ZK>System objects:</> System objects are tables which are either in the
ABAP Dictionary, or are internal SAP system tables, and cannot be
transported or used in BC Sets.
You can use the object &V1&, except for the invalid table(s), in BC
Sets.
The delivery class of the non-customizing object tables must be changed,
for you to be able to use the object in BC Sets. Contact the SAP
developer responsible for the object.
If a table is a system object, it cannot be used in BC Sets, regardless
if its delivery class.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
