How To Fix GLT1409 - Making subsequent changes to characteristics can lead to inconsistencies

SAP Error Message - Details

• Message type: E = Error

• Message class: GLT1 - Split processor: Maintain control tables

• Message number: 409

• Message text: Making subsequent changes to characteristics can lead to inconsistencies

What causes this issue?

In a <ZH>production system</>, the <ZH>subsequent </>inclusion of
document splitting characteristics for Controlling or the
post-capitalization of cash discounts to assets can cause
inconsistencies in document processing. Note that the changes to the
Customizing settings do not make corresponding adjustments to any
transaction data already posted.
&DEPENDENCIES&
If you subsequently add a new document splitting characteristic for
Controlling or subsequently capitalize cash discounts to assets, these
changes only apply to <ZH>new documents to be posted</>. If there is
transaction data in the current system or in the target system for this
change to the Customizing settings, note that there may be a delay
before the new setting takes effect.

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

Since there has not been a projection corresponding to the new document
splitting characteristics for the documents posted previously, account
assignments cannot be made completely for the documents already entered
in the system. The actual changes to the Customizing settings do not
make corresponding adjustments to any transaction data already present.
Consequently, the follow-on processes for documents that already exist
do not have complete account assignments either.
<ZH>Example:</>
The post-capitalization of cash discounts to assets does not occur if
the related invoices have not been posted with the changed settings.
When new document splitting characteristics are defined for Controlling,
postings cannot be made to the affected accounts that are defined as
cost elements if no default derivation relevant to Controlling has been
entered or if the existing data has not been migrated.

System Response

<ZH>If production data has already been entered in the system, we
recommend not making subsequent changes to the Customizing settings if
possible</>. However, if the change is required, you need to perform a
check on the data posted previously to ensure that subsequent problems
do not occur in production systems.
Ensure that there is a Controlling-relevant default derivation for the
affected accounts.
In cases involving the post-capitalization of cash discounts to assets,
you can manually adjust cash discounts to assets.

How to fix this error?

Check whether the desired changes to the Customizing settings are
<ZH>essential</>. Ensure that the changes you make to the Customizing
settings do not have any critical consequences. For detailed information
on this subject, see <ZH>SAP Note 891144</>.
Any transaction data present must also be converted accordingly. Note
that there are currently no standardized migration tools available for
converting transaction data that has already been posted. For detailed
and up-to-date information on this subject, see <ZH>SAP Note 812919.</>
