• What is the cause and solution for SAP error message RSDS058 - Access method &1 is not compatible with multi-segment sources ?

  The SAP error message RSDS058 indicates that there is an issue with the access method being used for a multi-segment source in SAP BW (Business Warehouse). This error typically arises when you are trying to use an access method that is not compatible with the data source you are working with, particularly when dealing with multi-segment sources.
  Cause:
  The error occurs when:
  
  You are trying to use an access method that is not suitable for multi-segment data sources. Multi-segment sources are typically used for InfoObjects that have a hierarchical structure or are based on multiple characteristics.
  The data source configuration is not set up correctly, or the access method does not support the structure of the data being accessed.
  
  Solution:
  To resolve the RSDS058 error, you can take the following steps:
  
  
  Check the Access Method: 
  
  Ensure that the access method you are using is compatible with multi-segment sources. Common access methods include:
  
  Direct Access: Suitable for standard data sources.
  Generic Data Source: Can be used for multi-segment sources but may require specific configurations.
  
  
  If you are using a custom access method, verify that it supports multi-segment data.
  
  
  
  Modify the Data Source:
  
  If the data source is incorrectly configured, you may need to adjust its settings. Check the data source definition in the Data Warehousing Workbench (transaction RSA1) and ensure that it is set up correctly for multi-segment access.
  
  
  
  Use a Compatible Data Source:
  
  If the current data source cannot be modified to support the required access method, consider using a different data source that is compatible with the access method you intend to use.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific access method and multi-segment sources to ensure you are following best practices.
  
  
  
  Check for Updates:
  
  Ensure that your SAP system is up to date with the latest patches and updates, as there may be fixes or enhancements related to data source handling.
