  The SAP error message SADL_EXPOSURE059 indicates that there is a structural issue with the way entities are defined in your SAP system, particularly in the context of the SAP Data Access Layer (SADL). This error typically arises when there is a mismatch in the hierarchy of entities, specifically when an entity is expected to be a subnode of another entity but is not defined as such.
  Cause:
  The error occurs when:
  
  You have defined a base view (entity) that is a subnode, but the related entity (subnode) is not correctly defined as a subnode of that base view.
  The data model is not aligned correctly, leading to inconsistencies in the expected hierarchy of entities.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Entity Definitions:
  
  Review the definitions of both the base view (&1) and the entity (&2) in your data model.
  Ensure that the entity (&2) is correctly defined as a subnode of the base view (&1).
  
  
  
  Adjust the Data Model:
  
  If the entity is not correctly defined, you may need to adjust the data model to reflect the correct hierarchy.
  This may involve modifying the metadata or the configuration of the entities in the SAP system.
  
  
  
  Rebuild the Data Model:
  
  If necessary, you may need to rebuild or regenerate the data model to ensure that all entities are correctly aligned.
  Use transaction codes like SE11 (Data Dictionary) or SE80 (Object Navigator) to make the necessary changes.
  
  
  
  Check for Dependencies:
  
  Ensure that there are no other dependencies or references that might be causing the issue.
  Look for any related views or entities that might also need to be adjusted.
  
  
  
  Test the Changes:
