How To Fix KX457 - Generation of check tables; Assignment of numbers

KX457 - Overview

• Message type: E = Error

• Message class: KX - EC-EIS/EC-BP: Data basis, data collection

• Message number: 457

• Message text: Generation of check tables; Assignment of numbers

What causes this issue?

When you edit characteristics, check tables are created for newly
defined characteristics. A check table contains the permitted values of
a characteristic; during data entry a data record and its
characteristic values are verified with the relevant check tables.
New check tables must be created for some of the characteristics
currently being edited. The name of the check table is formed
synthetically using a prefix (for example, 'T27' ,'T25' or
'/1SAP1/FC_TFG2') and a two-digit number as a suffix. This number can
be allocated
manually or automatically.
In both cases the system will verify that the resulting name is still
free for use.

How to fix this error?

Decide whether you will manually assign the check table numbers or if
they are to be allocated automatically (consecutively) by the system.
If your R/3 entire configuration consists of just one system, you can
choose automatic allocation. In the case of several R/3 Systems, you
should choose manual allocation.
For the allocation note the following general points.:
The check tables are created cross-client in the ABAP Dictionary and in
the database, this means that they are valid system-wide. If
Customizing is carried out in parallel in different R/3 Systems, for
example in the test system and the production system, you must ensure
that the check tables are also unique system-wide. Otherwise a
subsequent merging by transport would no longer be possible (name
conflict).

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

Example: in a test system a check table 'T2724' is created in
Customizing for a characteristic C2. In the production system, that up
to now has had the same status as the test system, post-Customizing is
carried out. A check table 'T2724' (with a different meaning) is also
created here for a characteristic C3 since the number 24 is not yet
taken in this system. From this point onwards it is not possible to
transport from the test system to the production system.
SAP recommendation:
Allocate the check table numbers manually and take organizational steps
to ensure that the same numbers are not allocated in two separate
systems.
Example of organizational steps:
Assign disjuct 10 number areas for the test and production systems so
that you can carry out transports later and avoid name conflicts (test
system - low numbers, production system - high numbers).
Allocate appropriate authorizations so that users can only generate in
the test system and so that the production system is supplied
exclusively by transports from the test system.
