What causes this issue?

The table to be logged &V1& is larger than the log table.

System Response

Logging is not possible.

How to fix this error?

Increase the size of field LOGDATA in log table DBTABLOG to at least
&V2& bytes. To do this, you have to increase the size of the LOGDATA
domain to at least &V2& bytes. Activate the settings and restart the
system. You can then set up the log for table &V1&.
Adhere to this sequence when you are transporting the changes to other
systems. First transport the changed domain and then restart the
destination system. Then transport the log settings for table &V1&.
Check whether logging is relevant for these tables. Note that logging a
large table can lead to large data volumes.

• What is the cause and solution for SAP error message AUT066 - Table larger than log table; log not possible ?

  The SAP error message AUT066: Table larger than log table; log not possible typically occurs in the context of change document logging in SAP. This error indicates that the size of the table you are trying to log changes for exceeds the maximum size allowed for the change log table. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Table Size Exceeds Limit: The primary reason for this error is that the table you are trying to log changes for has grown larger than the predefined limit for the change log table. SAP has certain limits on the size of tables that can be logged for changes, and if the table exceeds this limit, logging cannot be performed.
  Configuration Settings: The configuration settings for change document logging may not be properly set, leading to this error.
  Database Constraints: The underlying database may have constraints or limitations that affect the ability to log changes for large tables.
  
  Solutions:
  
  Review Table Size: Check the size of the table in question. If it is indeed larger than the allowed limit, consider whether logging is necessary for this table.
  Disable Change Logging: If logging is not essential for the table, you can disable change logging for that table. This can be done in the Data Dictionary (SE11) by modifying the table's logging settings.
  Partitioning: If the table is too large, consider partitioning the table if your database supports it. This can help manage the size and potentially allow for logging.
  Archiving: Implement an archiving strategy for the data in the table to reduce its size. This can help bring the table size within acceptable limits.
  Database Configuration: Review the database configuration and settings to ensure that they are optimized for handling large tables and logging.
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or patches related to this error.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like SE11 (Data Dictionary) to check the table definitions and logging settings.
  Change Document Objects: Review the change document objects associated with the table to understand how logging is configured.
  SAP Documentation: Refer to SAP documentation for guidelines on change document logging and limitations regarding table sizes.
  Performance Considerations: Keep in mind that enabling logging for very large tables can have performance implications, so it’s essential to evaluate the necessity of logging based on business requirements.
