• What is the cause and solution for SAP error message RSSDA029 - Direct read access on single SPO partition not supported with SDA: &1 ?

  The SAP error message RSSDA029 indicates that there is an attempt to perform direct read access on a single partition of a SAP HANA Smart Data Access (SDA) source, which is not supported. This typically occurs when you are trying to access data from a remote source that is partitioned, and the system does not allow direct reads from individual partitions.
  Cause:
  The error is caused by the following:
  
  The query is attempting to access a specific partition of a remote data source using SDA.
  SAP HANA does not support direct read access on individual partitions of a remote source.
  The data source may be a database that is partitioned, and the query is not structured to handle the partitioning correctly.
  
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Modify the Query: Instead of trying to access a specific partition, modify your query to access the entire table or view without specifying a partition. This way, the query will not attempt to perform direct read access on a single partition.
  
  
  Use a Virtual Table: If you need to work with specific partitions, consider creating a virtual table that combines the data from the partitions you need. This can be done by creating a view in the remote database that unifies the data across partitions.
  
  
  Check Data Source Configuration: Ensure that the SDA data source is configured correctly. Sometimes, issues with the configuration can lead to unexpected behavior.
  
  
  Consult Documentation: Review the SAP HANA documentation for Smart Data Access to understand the limitations and best practices for accessing remote data sources.
  
  
  Contact SAP Support: If the issue persists and you cannot find a suitable workaround, consider reaching out to SAP support for assistance. They may provide insights specific to your environment or version.
  
  
  Related Information:
  
  SAP HANA Smart Data Access (SDA): This feature allows you to access data from remote sources as if it were local to the SAP HANA database. However, there are limitations regarding how data can be accessed, especially with partitioned sources.
  Partitioning in Databases: Understanding how partitioning works in the underlying database can help you design queries that avoid direct access issues.
  Performance Considerations: When working with SDA, be aware of performance implications, especially when accessing large datasets or complex queries.
  
  By following these steps, you should be able to address the RSSDA029 error and successfully access the data you need.
