This error typically arises in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when dealing with hierarchies in InfoObjects or other data structures.
  Cause:
  The error can occur due to several reasons:
  
  Invalid Child ID: The child ID referenced in the hierarchy does not exist or is not valid. This could be due to data inconsistencies or corruption.
  Hierarchy Structure Issues: The hierarchy may not be properly defined, or there may be issues with the parent-child relationships.
  Data Load Issues: If data is being loaded into the system, there may be problems with the data source or transformation processes that lead to invalid entries.
  Configuration Errors: Incorrect configuration settings in the hierarchy definition or in the InfoObject settings can lead to this error.
  
  Solution:
  To resolve the UJA_EXCEPTION104 error, you can take the following steps:
  
  
  Check Hierarchy Definition:
  
  Go to the hierarchy definition in the SAP BW system and verify that the child ID exists and is correctly defined.

  Validate Data:

  Use transaction codes like RSA1 (Data Warehousing Workbench) to analyze the InfoObject and its hierarchy.
  
  
  
  Rebuild Hierarchy:
  
  If the hierarchy is corrupted, consider rebuilding it. You can delete the existing hierarchy and recreate it from scratch, ensuring that all IDs are valid.
  
  
  
  Check for Data Load Errors:
