• What is the cause and solution for SAP error message COM_ALTER_IDENT207 - Automatic generation is only possible for one table ?

  The SAP error message COM_ALTER_IDENT207 indicates that there is an issue with the automatic generation of identifiers (like primary keys or unique constraints) in a database context, specifically when trying to alter multiple tables at once. This error typically arises in scenarios involving database operations where the system expects to handle only one table at a time for automatic identifier generation.
  Cause:
  The primary cause of this error is that the operation you are attempting to perform is trying to alter or generate identifiers for more than one table simultaneously. SAP's database management system is designed to handle identifier generation for a single table at a time, and when it detects an attempt to process multiple tables, it raises this error.
  Solution:
  To resolve the COM_ALTER_IDENT207 error, you can follow these steps:
  
  
  Check Your Operation: Review the operation you are trying to perform. Ensure that you are only attempting to alter or generate identifiers for one table at a time.
  
  
  Separate Operations: If you need to perform operations on multiple tables, break them down into individual operations. Execute the identifier generation or alteration for each table separately.
  
  
  Review Code or Configuration: If this error is occurring in a custom program or during a specific transaction, review the code or configuration to ensure that it adheres to the requirement of handling one table at a time.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on identifier generation and table alterations to ensure compliance with best practices.
  
  
  Check for Locks or Transactions: Ensure that there are no locks or ongoing transactions that might be affecting the ability to alter the table. Sometimes, concurrent operations can lead to unexpected behavior.
  
  
  Database Consistency: Ensure that the database is in a consistent state. If there are any inconsistencies, resolve them before attempting the operation again.
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error. SAP frequently updates its knowledge base with solutions to common problems.
  Transaction Codes: Familiarize yourself with relevant transaction codes that might be involved in the operation you are performing (e.g., SE11 for Data Dictionary, SE14 for database utility).
  Database Management: Understanding how SAP interacts with the underlying database (like HANA, Oracle, etc.) can provide insights into how to manage tables and identifiers effectively.
  
  If the problem persists after following these steps, consider reaching out to SAP support or consulting with a technical expert who specializes in SAP database management.
