• What is the cause and solution for SAP error message DA653 - &: Pooled tables and cluster tables are no longer supported ?

  The SAP error message DA653 indicates that you are trying to use pooled tables or cluster tables in a context where they are no longer supported. This typically occurs in newer versions of SAP systems, particularly with the introduction of the SAP HANA database, which does not support these types of tables.
  Cause:
  
  Pooled Tables and Cluster Tables: These are special types of database tables used in older versions of SAP. Pooled tables are used to store data from multiple logical tables in a single physical table, while cluster tables store related data in a single table.
  Database Compatibility: With the shift to SAP HANA, which is a columnar database, the architecture has changed, and pooled and cluster tables are not compatible with this new database structure.
  Legacy Code: If you have custom code or legacy programs that reference these types of tables, they may trigger this error when executed in an environment that does not support them.
  
  Solution:
  
  Identify Usage: Determine where pooled or cluster tables are being used in your code or data model. This can include custom programs, reports, or data extraction processes.
  Replace with Transparent Tables: Convert the logic that relies on pooled or cluster tables to use transparent tables instead. Transparent tables are the standard table type in SAP and are fully supported in SAP HANA.
  Data Migration: If you have data stored in pooled or cluster tables, you may need to migrate this data to transparent tables. This can involve creating new transparent tables and writing data migration scripts to transfer the data.
  Update ABAP Code: Modify any ABAP code that references the old table types to use the new transparent tables. This may involve changing SELECT statements, data processing logic, and any other references to the old tables.
  Testing: After making changes, thoroughly test the affected programs and processes to ensure they work correctly with the new table structures.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any specific guidance or updates related to this error. SAP frequently publishes notes that provide solutions or workarounds for common issues.
  Documentation: Review SAP documentation regarding database changes, especially if you are migrating from an older version of SAP to a newer version that uses HANA.
  Consult SAP Community: Engage with the SAP Community or forums for additional insights and experiences from other users who may have encountered similar issues.
  
  By addressing the use of pooled and cluster tables and transitioning to supported table types, you can resolve the DA653 error and ensure compatibility with your SAP environment.
