• What is the cause and solution for SAP error message CNV_PE_SEL025 - Preselection table &1 already available ?

  The SAP error message CNV_PE_SEL025 indicates that a preselection table (identified by &1) is already available in the system. This error typically occurs during data migration or conversion processes, particularly when using SAP's tools for data migration, such as the SAP S/4HANA Migration Cockpit or other data conversion tools.
  Cause:
  The error is caused by an attempt to create or load a preselection table that already exists in the database. This can happen if:
  
  The migration process was run multiple times without clearing the previous data.
  There was an interruption in the previous migration process, leaving the preselection table in an incomplete state.
  The same migration scenario is being executed again without proper cleanup.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Preselection Tables:
  
  Use transaction codes like SE11 (Data Dictionary) or SE16 (Data Browser) to check if the preselection table already exists in the database.
  Identify the records in the preselection table that may need to be cleared or updated.
  
  
  
  Delete or Clear the Preselection Table:
  
  If the preselection table is no longer needed, you can delete it. This can typically be done through the migration tool or directly in the database (if you have the necessary authorizations).
  If you want to keep the data for reference, consider archiving it instead of deleting.
  
  
  
  Re-run the Migration Process:
  
  After clearing the preselection table, re-run the migration process to create a new preselection table.
  
  
  
  Check for Errors in Previous Runs:
  
  Review logs or error messages from previous migration attempts to ensure that there are no underlying issues that need to be addressed.
  
  
  
  Consult Documentation:
  
  Refer to the official SAP documentation for the specific migration tool you are using. There may be specific instructions or best practices for handling preselection tables.
