Was verursacht dieses Problem?

When you save or change a derivation structure, the system creates a
table that stores the corresponding derivation rules.
The name of this table consists of the prefix 'K9' and a 3-digit number
('nnn'). You can assign this number manually or have the system do it
automatically. In either case, the system checks whether the name
'K9nnn' is still available.

Wie behebe ich diesen Fehler?

Decide whether you want to assign the table numbers manually or have the
system do it automatically. If your entire ERP configuration consists of
only one <LS>SAP ERP Central Component system</> (ECC system), you can
choose automatic number assignment. If you have several ECC systems, you
should assign them manually.
Note the following when assigning these numbers:
The tables are stored under the name 'K9nnn' in the ABAP/4 Dictionary
and are valid for all clients. If you customize in more than one ECC
system at the same time, you need to make sure that the table names are
unique in all systems. Otherwise, it will not be possible to transport
them to the same system later due to a naming conflict.

Das System gibt eine Fehlermeldung aus und erlaubt Ihnen nicht, mit dieser Transaktion fortzufahren, bis der Fehler behoben ist.

Example: You create a table 'K9100' for derivation structure AB1 during
customizing in your test system. At the same time, you also customize in
your productive system, which previously had the same status as the test
system, and the system creates a table 'K9100' for derivation structure
AB2 (with a different meaning). This is possible because the number 100
has not been taken yet in the productive system. Once this has happened,
it is no longer possible to transport derivation structure AB1 from the
test system to the productive system.
SAP recommendation:
Assign the table numbers manually, making sure that you do not assign
the same number in two different systems. For example, you could
assign different number ranges for your test system and your productive
system to avoid naming conflicts when you transport. Or
you can only authorize your users to create or change derivation
structures in the test system, and to transport these then to the
productive system.
