How To Fix CNV_40301055 - The value of &1 is different in &3

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 055

• 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 balance sheet account specified
in the title of this text (&V2&) is different. This balance sheet
account is used when posting asset values from FI-AA to the general
ledger.
The values of the balance sheet 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 balance sheet 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 show
the account values as they will be <ZH>after </>the conversion (based on
mapping specified in the chart of accounts conversion).
In the new asset account determination of this merge only one value
(dependent on the priority indicator settings) is taken for this balance
sheet account.

System Response

After the conversion, assets that are created will automatically use the
balance sheet accounts that are specified in the relevant asset account
determination Customizing.
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 balance sheet account are transferred to the new balance
sheet account (the new account after the conversion).

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

How to fix this error?

Check your mapping for correctness.

account) is determined by the activity <ZK>Determine Amounts to be

This error indicates that there is a discrepancy in the value of a field between the source and target systems or between different records in the same system.
  Cause:
  The error message CNV_40301055 is triggered when:
  
  The value of a specific field (denoted by &1) in the source data does not match the expected value in the target system or in another related field (denoted by &3).
