How To Fix CNV_40301071 - The value of &1 will be initial after conversion of &3

CNV_40301071 - Overview

• Message type: E = Error

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

• Message number: 071

• Message text: The value of &1 will be initial after conversion of &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 table field (&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.
<ZH>Because of the merge, the value of the balance sheet account for the
new asset account determination will be initial.</>
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 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.
&ADDITIONAL_HINTS&
The amount which is to be transferred (for each asset and balance sheet
account) is determined by the activity <ZK>Determine Amounts to be
Transferred in phase Preprocessing programs DURING system lock.</>
The actual transfer is done by activity <ZK>Transfer Amounts for Assets
in phase Postprocessing programs DURING system lock.</>

CNV_40301071 - Details

• The SAP error message CNV_40301071 indicates that during a data conversion process, a specific value (represented by &1) will be set to an initial (or empty) state after the conversion of a particular field (represented by &3). This typically occurs in the context of data migration or conversion projects, often when using SAP's tools for data migration, such as the SAP S/4HANA Migration Cockpit or other data conversion tools.
  
  Cause:
  The error can occur due to several reasons:
  
  Data Mapping Issues: The source data may not have a corresponding value in the target system, leading to the value being set to initial.
  Data Type Mismatch: The data type of the source field may not be compatible with the target field, resulting in the loss of data.
  Business Logic Constraints: Certain business rules or constraints in the target system may prevent the value from being retained.
  Missing Configuration: The target system may not be properly configured to
