How To Fix IV055 - Table & missing target structure for incremental conversion

SAP Error Message - Details

• Message type: E = Error

• Message class: IV - Elementary Steps of Incremental Conversion (ICNV)

• Message number: 055

• Message text: Table & missing target structure for incremental conversion

What causes this issue?

The given table was already converted incrementally prior to the
upgrade. A check showed that the target structure of the table used
differs from that provided by the upgrade. This means that the
definition of the table in the ABAP Dictionary would not be consistent
with its definition in the database after the incremental conversion.
This could for example be caused by Hot Packages or add-on solutions
being applied after starting the incremental conversion.

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

System Response

If the incremental conversion of the table took less than 2 hours prior
to the upgrade, the result of the ICNV for this table is simply
rejected and there is another standard conversion in phase PCON. In
this case you do not need to take any special steps.
However, if the conversion time prior to the upgrade was already longer
than 2 hours, phase PCON stops and you have to make a decision.

How to fix this error?

If phase PCON stops, you have two alternatives:
You can reject the result of the incremental conversion with
Transaction ICNV. Execute the function 'Edit->Reset conversion' and
then repeat phase PCON. The table is completely converted again in
phase PCON. If you have very large tables, this could have a negative
effect on the upgrade schedule and the system might not be productive
again in time.
If you want to use the results of ICNV and definitely do not want to
convert the table again, please contact R/3 Support immediately
(component BC-DWB-DIC-AC). It might be able to correct the problem,
avoiding another conversion of the table.
DO NOT IGNORE this message as it will cause problems in later upgrade
phasees and in production after the upgrade.

• What is the cause and solution for SAP error message IV055 - Table & missing target structure for incremental conversion ?

  The SAP error message IV055, which states "Table & missing target structure for incremental conversion," typically occurs during the data migration or conversion process, particularly when using the SAP Information Lifecycle Management (ILM) or similar data management tools. This error indicates that the system is unable to find the target structure for a specific table that is required for the incremental conversion process.
  Cause:
  
  Missing Target Structure: The target structure for the specified table is not defined in the system. This could happen if the table was not properly configured for the conversion process.
  Incorrect Configuration: The configuration settings for the data migration or conversion process may be incorrect or incomplete.
  Version Mismatch: There may be a version mismatch between the source and target systems, leading to discrepancies in the expected structures.
  Transport Issues: If the target structure was supposed to be transported from another system and the transport did not occur successfully, this error may arise.
  
  Solution:
  
  Check Target Structure: Verify that the target structure for the specified table is defined in the system. You can do this by checking the relevant configuration settings in the SAP system.
  Configuration Review: Review the configuration settings for the data migration or conversion process to ensure that all necessary tables and structures are correctly defined.
  Transport Check: If the target structure was supposed to be transported from another system, check the transport logs to ensure that the transport was successful and that the target structure exists in the target system.
  Consult Documentation: Refer to the SAP documentation for the specific data migration or conversion tool you are using to ensure that all prerequisites and configurations are met.
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error message or provide additional guidance.
  Testing: If possible, perform a test run of the conversion process to identify any other potential issues that may arise.
  
  Related Information:
  
  SAP Help Portal: The SAP Help Portal contains documentation on data migration and conversion processes, including best practices and troubleshooting steps.
