How To Fix CNV_10020336 - Direct determination by &2 has failed: &3 is initial

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 336

• Message text: Direct determination by &2 has failed: &3 is initial

What causes this issue?

Direct determination by &V2& has been specified for conversion of table
field &V1&. <ZH>Delimitation takes place.</>
The related source field or object &V3& is not filled for the current
data record. Consequently, it is not possible to assign the field to be
converted to &V2&.

System Response

<ZH> Field &V1& of the current data record does not participate in the
conversion.</>

How to fix this error?

Check if field &V1& really contains relevant data for the records for
which source field or object &V3& is empty. If this is the case, you
need to find a different path for determination of &V2& using another
source field or object and store it in table CNV_10020_DTFLD.
&HINTS&

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

If the determination path is the same for a multitude of table fields
to be converted, determination is carried out only once for this group
of fields. Consequently, the problem described above occurs with all
fields of a group, and all instances must be analyzed separately.
If package parameter PROTOCOL_ENHANCED is set, the system outputs the
value of the relevant fields (if they are filled) after this message has
been output. If <zh>all</> relevant fields are empty, no message is
output.
If tables are delimited by means of a cluster table, output of the
relevant fields for conversion is not possible.

• What is the cause and solution for SAP error message CNV_10020336 - Direct determination by &2 has failed: &3 is initial ?

  The SAP error message CNV_10020336 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. The message indicates that a direct determination process has failed because a required field (denoted as &3) is empty or uninitialized (i.e., "initial").
  Cause:
  The error is caused by the system attempting to derive or determine a value for a specific field based on another field (&2), but it fails because the value it needs to work with is not available (it is "initial" or empty). This can happen for several reasons, including:
  
  Missing Data: The source data may not contain the necessary information for the conversion.
  Incorrect Mapping: The mapping configuration may not be set up correctly, leading to the inability to derive the required value.
  Data Quality Issues: There may be issues with the quality of the data being migrated, such as missing mandatory fields.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Source Data: Review the source data to ensure that all required fields are populated. Look specifically at the field that is indicated as &3 in the error message.
  
  
  Review Mapping Configuration: Verify the mapping settings in the migration tool. Ensure that the mappings are correctly defined and that the source fields are correctly linked to the target fields.
  
  
  Data Validation: Perform data validation checks to identify any records that may be missing required information. You may need to clean or enrich the data before attempting the migration again.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using. There may be additional guidelines or prerequisites that need to be met.
  
  
  Error Logs: Check the detailed error logs for more context on the failure. This can provide insights into which specific records are causing the issue.
  
  
  Testing: If possible, run a test migration with a smaller dataset to isolate the problem and ensure that the mappings and data are correct.
