• What is the cause and solution for SAP error message /AIF/PERS_TBL_GEN013 - Resulting db-schema contains an existing table; change prefix ?

  The SAP error message /AIF/PERS_TBL_GEN013 indicates that there is an issue with the generation of a database schema for a table in the Application Interface Framework (AIF). Specifically, the error states that the resulting database schema contains a table that already exists, and it suggests changing the prefix to resolve the conflict.
  Cause:
  
  
  Existing Table Conflict: The error typically occurs when you attempt to create a new table in the database, but a table with the same name (or prefix) already exists. This can happen if:
  
  The table was previously created and not properly deleted.
  There is a naming conflict with another application or component that uses the same prefix.
  
  
  
  Incorrect Configuration: The configuration settings for the AIF might be set in such a way that they lead to the generation of a table name that conflicts with existing tables.
  
  
  Solution:
  
  
  Change the Prefix:
  
  Go to the AIF configuration settings where you define the table prefix.
  Change the prefix to something unique that does not conflict with existing tables.
  After changing the prefix, regenerate the database schema.
  
  
  
  Check Existing Tables:
  
  Use transaction codes like SE11 (Data Dictionary) or SE14 (Database Utility) to check if the table already exists.
  If the table is no longer needed, you can delete it (ensure you have backups and that it is safe to do so).
  
  
  
  Regenerate the Schema:
  
  After making the necessary changes, regenerate the database schema for the AIF interface.
  This can usually be done through the AIF configuration transaction.
  
  
  
  Review Documentation:
  
  Check the SAP documentation for AIF to ensure that you are following the correct procedures for table generation and naming conventions.
  
  
  
  Related Information:
  
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  SE11: Data Dictionary for checking existing tables.
  SE14: Database Utility for managing database objects.
  SICF: For checking service configurations if applicable.
  
  
  
  SAP Notes: Look for SAP Notes related to AIF and database schema generation. These notes may provide additional insights or patches that could resolve the issue.
  
  
  Community Forums: Consider checking SAP Community forums or other user groups for similar issues and solutions shared by other users.
  
  
  Backup: Always ensure that you have a backup of your database and configurations before making changes, especially when deleting tables or modifying prefixes.
  
  
  By following these steps, you should be able to resolve the error and successfully generate the required database schema for your AIF implementation.
