• What is the cause and solution for SAP error message RSDA_SYB191 - Table "&1": Partition "&2" must never be dropped ?

  The SAP error message RSDA_SYB191 indicates that there is an issue related to the handling of partitions in a Sybase database. Specifically, the message states that a certain partition of a table must never be dropped, which can occur in scenarios involving data extraction or data management processes.
  Cause:
  This error typically arises in the following situations:
  
  Partition Management: The system is attempting to drop a partition of a table that is configured to be non-droppable. This can happen if the partition is still in use or if it is part of a configuration that prevents it from being removed.
  Data Extraction: If you are using SAP Data Services or SAP BW (Business Warehouse) to extract data from a Sybase database, the extraction process may be trying to drop a partition that is not allowed to be dropped.
  Configuration Issues: There may be a misconfiguration in the way the partitions are set up in the database or in the SAP system.
  
  Solution:
  To resolve the RSDA_SYB191 error, consider the following steps:
  
  
  Check Partition Configuration: Review the partitioning strategy for the table in question. Ensure that the partitions are configured correctly and that the one being referenced is indeed meant to be non-droppable.
  
  
  Review Data Extraction Logic: If this error occurs during a data extraction process, check the logic in your data flow or extraction process. Ensure that it does not attempt to drop partitions that are not meant to be dropped.
  
  
  Database Administration: Consult with your database administrator to understand the partitioning rules and constraints applied to the table. They may need to adjust the partitioning strategy or provide insights into why the partition cannot be dropped.
  
  
  SAP Notes and Documentation: Look for relevant SAP Notes or documentation that may provide additional context or solutions for this specific error. SAP's support portal can be a valuable resource.
