EM001 - Details

• The SAP error message EM001, which states "Delete all the substructures first," typically occurs when you are trying to delete a structure or an object that has dependent substructures or components. This is common in various SAP modules, especially in areas like customizing, data modeling, or configuration where hierarchical relationships exist.
  
  Cause:
  The error arises because the system enforces referential integrity. If a structure has substructures or components that depend on it, you cannot delete the parent structure until all dependent substructures are removed. This is to prevent orphaned records or inconsistencies in the data model.
  
  Solution:
  To resolve this error, follow these steps:
  
  
  Identify Substructures: Determine which substructures or components are linked to the structure you are trying to delete. This can often be done by checking the hierarchy or dependencies in the relevant transaction or configuration screen.
  
  
  Delete Substructures: Before you can delete the main structure, you need to delete all the substructures. Navigate
