  The SAP error message RSDD_LM157 indicates that a navigational attribute specified in a query or report does not exist in the context of the data model being used. This typically occurs in SAP BW (Business Warehouse) or SAP BW/4HANA environments when a query is trying to access a navigational attribute that has not been defined or is not available in the InfoObject or InfoProvider being queried.
  Cause:
  
  Missing Navigational Attribute: The navigational attribute specified in the query is not defined in the InfoObject.
  Incorrect Query Definition: The query may be incorrectly defined, referencing attributes that are not part of the InfoObject.
  Changes in Data Model: If there have been recent changes to the data model (e.g., InfoObject modifications, deletions, or changes in the InfoProvider), the query may reference attributes that no longer exist.
  Transport Issues: If the query was transported from one system to another, the navigational attributes may not have been included in the transport.
  
  Solution:
  
  Check InfoObject Definition: Verify that the navigational attribute exists in the InfoObject. You can do this by navigating to the InfoObject in the SAP BW modeling tools and checking its attributes.
  Update Query: If the navigational attribute does not exist, you may need to update the query to remove the reference to the non-existent attribute or replace it with a valid one.
  Rebuild Query: If the query is complex, consider rebuilding it to ensure that all navigational attributes are correctly referenced.
  Transport Check: If the issue arose after a transport, ensure that all necessary objects, including InfoObjects and their attributes, were included in the transport request.
  Check for Changes: If there have been recent changes to the data model, ensure that the query is updated accordingly to reflect those changes.
