• What is the cause and solution for SAP error message IL816 - The second level &1 must be greater than the first level &2 ?

  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.

  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, and that the second level is indeed greater than the first level.
  
  
  
  Adjust Level Definitions:
  
  If you find that the levels are incorrectly defined, adjust them accordingly in the configuration settings.
  Make sure that the relationships between the levels are logical and follow the required hierarchy.
