How To Fix CNV_10020334 - Path determination for &2 has failed: Source value for &3 is initial

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 334

• Message text: Path determination for &2 has failed: Source value for &3 is initial

What causes this issue?

Determination by path &V2& has been specified for conversion of table
field &V1&. <ZH>No 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 &V4&.

System Response

<ZH> Field &V1& of the current data record participates in the
conversion.</>
However the conversion routine is supplied with an empty value for
&V4&.

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 &V4& 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
related fields for conversion is not possible.

• What is the cause and solution for SAP error message CNV_10020334 - Path determination for &2 has failed: Source value for &3 is initial ?

  The SAP error message CNV_10020334 indicates that there is an issue with path determination in a conversion or migration process, specifically related to the source value being initial (or empty) for a certain field. This error typically arises during data migration or conversion processes, often when using SAP's Data Migration tools or during system conversions.
  Cause:
  
  Initial Source Value: The error suggests that the source value for a specific field (denoted as &3 in the message) is empty or not populated. This can happen if the data being migrated does not have a corresponding value in the source system.
  Configuration Issues: There may be issues with the configuration of the path determination logic, which could be expecting a non-empty value to determine the correct path.
  Data Mapping Errors: The mapping between the source and target systems may not be correctly defined, leading to situations where the expected values are not available.
  
  Solution:
  
  Check Source Data: Review the source data to ensure that the field in question (&3) is populated. If it is empty, you may need to correct the data in the source system or provide a default value.
  Review Path Determination Logic: Examine the configuration for path determination to ensure that it is set up correctly. This may involve checking the rules or conditions that dictate how paths are determined based on source values.
  Data Mapping Review: Ensure that the mapping between the source and target systems is correctly defined. If necessary, update the mapping to ensure that all required fields are populated.
  Debugging: If the issue persists, consider enabling debugging or logging to get more detailed information about the path determination process and identify where it is failing.
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration or conversion process you are using, as there may be known issues or additional configuration steps required.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on data migration issues.
  Transaction Codes: Familiarize yourself with transaction codes related to data migration, such as LSMW (Legacy System Migration Workbench) or other tools you may be using.
  Community Forums: Consider searching or posting in SAP community forums or support channels for additional insights from other users who may have encountered similar issues.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to resolve it.
