• What is the cause and solution for SAP error message RSRMON018 - Read during navigation/hierarchy drilldown ?

  The SAP error message RSRMON018 typically occurs in the context of SAP BW (Business Warehouse) when users attempt to navigate or drill down into a hierarchy in a report or query, and the system encounters an issue while trying to read the data. This error can be caused by several factors, and understanding the root cause is essential for finding a solution.
  Causes of RSRMON018
  
  
  Data Inconsistency: There may be inconsistencies in the data stored in the InfoObjects or InfoProviders that are being queried. This can happen if the data was not loaded correctly or if there are issues with the data model.
  
  
  Hierarchy Issues: The hierarchy being used may not be properly defined or may have been changed after the data was loaded. This can lead to problems when the system tries to read the hierarchy structure.
  
  
  Authorization Issues: The user may not have the necessary authorizations to access certain data or hierarchies, leading to read errors.
  
  
  Performance Issues: If the system is under heavy load or if there are performance bottlenecks, it may lead to timeouts or read errors during navigation.
  
  
  Technical Issues: There may be technical issues with the BW system itself, such as problems with the database or the underlying data structures.
  
  
  Solutions to RSRMON018
  
  
  Check Data Consistency:
  
  Verify that the data in the InfoObjects and InfoProviders is consistent and correctly loaded. You can use transaction codes like RSA1 to check the data loading process and ensure there are no errors.
  
  
  
  Review Hierarchy Definitions:
  
  Check the hierarchy definitions in the BW system. Ensure that the hierarchy is correctly defined and that all nodes are properly linked. You can do this in the hierarchy maintenance area.

  Technical Support:
  
  If the issue persists, consider reaching out to your SAP Basis team or technical support for further investigation. They can check for any underlying technical issues that may be causing the error.
