How To Fix CNV_10020338 - Path determination for &2 has failed: there is no target value for &3

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 338

• Message text: Path determination for &2 has failed: there is no target value for &3

What causes this issue?

Determination by path &V2& has been specified for conversion of table
field &V1&. <ZH>Delimitation takes place.</>
No target value for &V4& can be determined for the current data record
using the assigned source field or object &V3& and path &V2&.
Consequently, it is not possible to assign the field to be converted to
&V4&.

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 with
source field or object &V3&. If this is the case, you need to find a
different path for determination of &V4& 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_10020338 - Path determination for &2 has failed: there is no target value for &3 ?

  The SAP error message CNV_10020338 indicates that there is an issue with path determination in a conversion or migration process, specifically that there is no target value defined for a certain field or parameter. This error typically arises during data migration or conversion activities, often when using SAP's Data Migration tools or during system upgrades.
  Cause:
  The error message suggests that the system is trying to determine a path for a specific object (indicated by &2), but it cannot find a corresponding target value for a specific field (indicated by &3). This can happen due to several reasons:
  
  Missing Configuration: The target value for the specified field may not be configured in the system.
  Data Mapping Issues: There may be a problem with the mapping of source data to target data, where the expected target value is not defined.
  Incomplete Migration Settings: The migration settings may not have been fully defined or may be missing necessary entries.
  Custom Development: If there are custom developments or enhancements, they may not be correctly set up to handle the path determination.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Configuration: Verify that the target values for the specified field are correctly configured in the system. This may involve checking the relevant customizing settings in the SAP system.
  
  
  Review Data Mapping: Ensure that the data mapping between the source and target systems is correctly defined. You may need to adjust the mapping to include the missing target value.
  
  
  Examine Migration Settings: Review the migration settings to ensure that all necessary parameters and values are defined. This may involve checking the migration cockpit or the specific migration tool being used.
  
  
  Debugging: If you have access to the development environment, you can debug the process to identify where the path determination is failing. This may provide insights into why the target value is missing.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration or conversion process you are using. There may be known issues or additional configuration steps required.
  
  
  Contact SAP Support: If the issue persists and you cannot identify the cause, consider reaching out to SAP support for assistance. They may have additional insights or patches available for your specific situation.
