IL816 - Details

• The SAP error message IL816 indicates that there is an issue with the configuration of a hierarchical structure, typically in the context of a bill of materials (BOM) or a similar structure where levels are defined. The message states that the second level must be greater than the first level, which suggests that there is a problem with the way the levels are defined in the hierarchy.
  
  Cause:
  The error usually occurs when:
  
  The levels defined in the hierarchy are incorrectly set up, meaning that the second level is not greater than the first level.
  There may be a misconfiguration in the master data or the BOM structure.
  The system is trying to process a hierarchy where the relationships between levels are not correctly defined.
  
  
  Solution:
  To resolve the IL816 error, you can take the following steps:
  
  
  Check the Hierarchical Structure:
  
  Review the hierarchical structure you are working with (e.g., BOM, routing, etc.).
  Ensure that the levels are defined correctly,
