How To Fix KE458 - Saving/changing of derivation structures; number assignment

KE458 - Overview

• Message type: E = Error

• Message class: KE -

• Message number: 458

• Message text: Saving/changing of derivation structures; number assignment

What causes this issue?

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.

How to fix this error?

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.

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

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.

• What is the cause and solution for SAP error message KE458 - Saving/changing of derivation structures; number assignment ?

  The SAP error message KE458 typically occurs in the context of the Controlling (CO) module, specifically when dealing with derivation structures in Profitability Analysis (CO-PA). This error indicates that there is an issue with saving or changing derivation structures, particularly related to number assignment.
  
  Cause:
  The error can be caused by several factors, including:
  
  
  Number Range Issues: The number range for the derivation structure may not be defined or may be exhausted. Each derivation structure requires a unique identifier, and if the system cannot assign a new number, it will trigger this error.
  
  
  Authorization Issues: The user may not have the necessary authorizations to create or modify derivation structures.
  
  
  Configuration Errors: There may be issues in the configuration of the CO-PA module or the derivation structure itself, such as missing or incorrect settings.
  
  
  Data Consistency Issues: There may be inconsistencies in the data that prevent the system from saving changes.
  
  
  
  Solution:
