How To Fix TG463 - Table & does not meet target structure for incremental conversion

SAP Error Message - Details

• Message type: E = Error

• Message class: TG - Messages for Upgrade Repository Switch

• Message number: 463

• Message text: Table & does not meet target structure for incremental conversion

What causes this issue?

This table has already been converted incrementally. A further check has
shown that the structure of the table differs from that displayed in the
ABAP Dictionary (SE11). This means that after the incremental conversion
there is an inconsistency between the definition in the ABAP Dictionary
and in the database. This may prevent the system from accessing the
table, causing application programs to terminate.

System Response

The upgrade phase PCON stops.

How to fix this error?

You have two options:
Use the transaction ICNV to reset the incremental conversion. Phase PCON
then adjusts the complete table again in the database. This may take a
long time. To do this, select the table and choose <ZH>Edit</> ->
<ZH>Reset conversion</>.
The definition of the table in the ABAP Dictionary is adjusted to the
existing target structure. This retains the result of the incremental
conversion. In this case, contact SAP Support (component BC-DWB-DIC-AC)
before taking any further action.
Never ignore this problem by continuing with the phase PCON and making
no corrections. Otherwise you will encounter problems in later upgrade
phases and during productive operation.

• What is the cause and solution for SAP error message TG463 - Table & does not meet target structure for incremental conversion ?

  The SAP error message TG463, which states "Table & does not meet target structure for incremental conversion," typically occurs during data migration or conversion processes, particularly when using tools like SAP S/4HANA Migration Cockpit or similar data transfer methods. This error indicates that the structure of the source table does not match the expected structure of the target table in the context of an incremental conversion.
  Cause:
  
  Schema Mismatch: The source table may have columns that are not present in the target table or may have different data types or constraints.
  Missing Fields: Required fields in the target structure may be missing from the source data.
  Data Type Incompatibility: The data types of the fields in the source table may not be compatible with those in the target table.
  Incorrect Mapping: The mapping configuration between the source and target tables may be incorrect or incomplete.
  Version Differences: If you are migrating from an older version of SAP to a newer one, there may be structural changes in the database tables.
  
  Solution:
  
  Check Table Structures: Compare the source and target table structures to identify discrepancies. You can use transaction codes like SE11 (Data Dictionary) to view the structures.
  Adjust Mapping: If you are using a migration tool, review the mapping configuration to ensure that all necessary fields are correctly mapped.
  Modify Source Data: If the source data is missing required fields or has incompatible data types, you may need to modify the source data to meet the target structure requirements.
  Update Data Types: Ensure that the data types in the source table match those in the target table. You may need to convert data types or adjust the data format.
  Consult Documentation: Refer to the SAP documentation for the specific migration or conversion process you are using. There may be specific guidelines or requirements for the tables involved.
  Use SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance.
  
  Related Information:
  
  SAP Migration Cockpit: If you are using the SAP Migration Cockpit, familiarize yourself with its features and capabilities, as well as the specific requirements for the data you are migrating.
  Data Dictionary (SE11): Use the Data Dictionary to analyze the structure of both the source and target tables.
  SAP Community: Engage with the SAP Community forums for insights from other users who may have encountered similar issues.
