• What is the cause and solution for SAP error message RSDS348 - A SAP HANA DataSource cannot have multiple segments ?

  The SAP error message RSDS348 indicates that a SAP HANA DataSource is incorrectly configured to have multiple segments, which is not allowed. This error typically arises when you are trying to create or modify a DataSource in SAP BW (Business Warehouse) that is based on a HANA view or table.
  Cause:
  The primary cause of this error is that the DataSource definition is attempting to include multiple segments (or multiple data sources) when only a single segment is allowed for a HANA DataSource. In SAP BW, a segment refers to a part of the data structure that can be used to define how data is extracted and loaded.
  Solution:
  To resolve the RSDS348 error, you can follow these steps:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource in the SAP BW system and check its configuration.
  Ensure that the DataSource is defined correctly and does not reference multiple segments.
  
  
  
  Modify the DataSource:
  
  If you find that the DataSource is incorrectly set up with multiple segments, you will need to modify it to ensure that it only has one segment.
  This may involve removing any additional segments or ensuring that the DataSource is pointing to a single HANA view or table.
  
  
  
  Recreate the DataSource:
  
  If modifying the existing DataSource does not resolve the issue, consider deleting the DataSource and recreating it from scratch, ensuring that you only define a single segment.
  
  
  
  Check HANA View:
  
  If the DataSource is based on a HANA view, check the view definition in HANA Studio to ensure that it is correctly set up and does not inadvertently create multiple segments.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to DataSource configuration for SAP HANA to ensure compliance with best practices.
