How To Fix CNV_40301050 - The value of &1 is different in &3

CNV_40301050 - Overview

• Message type: E = Error

• Message class: CNV_40301 - Message class for package 40301 (KTOGR)

• Message number: 050

• Message text: The value of &1 is different in &3

What causes this issue?

Asset account determinations &V3& are to be merged. In Customizing for
these asset account determinations, the G/L account specified in the
title of this text (&V2&) is different. This G/L account is used when
posting asset values from FI-AA to the general ledger.
The values of the G/L account (&V4&) are different for the chart of
accounts and deprecation area specified in the associated message in the
hierarchy that contains the context information.
If the asset account determination conversion also includes a chart of
accounts conversion, it is possible that the G/L accounts of the asset
account determination Customizing (which are specified for each chart of
accounts) are affected by the chart of accounts conversion. Note that in
this case, the two account values already reflect the account values as
they will be <ZH>after</> the conversion (based on mapping specified in
the chart of accounts conversion).
In the new account determination of this merge only one value (dependent
on the priority indicator settings) is taken for this G/L account.

System Response

After the conversion, assets that are created will automatically use the
G/L accounts that are specified in the relevant asset account
determination Customizing.

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

For assets that existed prior to the conversion, and which will receive
a new asset account determination during the conversion, amounts posted
to the old G/L account are <ZH>not</> transferred to the new G/L account
(the new account after the conversion).

How to fix this error?

Check your mapping for correctness.

Procedure for System Administrators

If required, transfer the corresponding value manually from the old to
the new G/L account.

  Data Type Mismatch: The data types of the fields being compared may not be compatible, leading to discrepancies in the values.
