How To Fix CNV_IUUC_TCR_MAIN009 - Alias table &1 for table &2 of cluster &3 could not be created (RC &4)

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_IUUC_TCR_MAIN - transactional consistent replication main package

• Message number: 009

• Message text: Alias table &1 for table &2 of cluster &3 could not be created (RC &4)

What causes this issue?

In order to read data from the logging table for a cluster table, a so
called alias table is needed. It represents the structure of the logical
cluster tables of the original cluster. However, the creation of the
alias table failed in the source system. The return codes help to
identify the source of the issue:
21X: It was not possible to retrieve the fields of the original logical
cluster table.
220: A table with the same name as the alias table already exists and
has a different structure.
23X: The creation or activation of the table in the source failed.

System Response

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

How to fix this error?

For return code 220, check the source system for the already existing
table. If the table exists, it was most likely created with different
settings. You need to verify whether the table in the source is correct.
If not, you can try to delete the table in the source and start the
creation process for the logging table again in the central system. It
is also possible that an inconsistency in the central system exists
where the wrong logging table / alias table name is associated with the
table and the table in the source is used for another application table.
In this case check the values in tables IUUC_TABLES<(>,<)>
IUUC_TCR_TABLES2 and IUUC_TCR_CLUS_ID for the respective tables and IDs.
For all other return codes, there is either a general issue in the
source system, or the logging table needs to be checked by an expert
(specifically how the logging table was created). Consult your SAP
contact in the project team.

  The SAP error message CNV_IUUC_TCR_MAIN009 indicates that there was an issue creating an alias table for a specific table in a cluster during a data migration or conversion process. This error is typically associated with the SAP Landscape Transformation (SLT) or the SAP Data Migration process.
  Cause:
  The error can occur due to several reasons, including:
  
  Database Issues: There may be issues with the underlying database, such as insufficient permissions, lack of space, or database locks.
  Configuration Problems: The configuration settings for the data migration or transformation process may not be set up correctly.
  Existing Objects: An alias table with the same name may already exist, causing a conflict.
  Cluster Table Issues: The cluster table itself may have issues, such as being locked or not being accessible.
  Transport Issues: If the system is in a transport environment, there may be issues with the transport layer.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  Check Database Permissions: Ensure that the user executing the migration has the necessary permissions to create tables in the database.
  Check for Existing Tables: Verify if an alias table with the same name already exists. If it does, you may need to drop it or rename it before retrying the operation.
  Review Configuration: Double-check the configuration settings for the data migration process to ensure they are correct.
  Database Space: Ensure that there is enough space in the database to create new tables.
  Check for Locks: Investigate if there are any locks on the cluster table or the database that might be preventing the creation of the alias table.
  Review Logs: Check the logs for more detailed error messages that might provide additional context on the failure.
  Retry the Operation: After addressing the above issues, retry the operation to see if the error persists.
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like SE11 (Data Dictionary) to check the structure of the tables involved or SE38 to run any relevant reports.
