• What is the cause and solution for SAP error message COM_DML_ENGINE013 - Object type & only allows a strict hierarchy ?

  The SAP error message COM_DML_ENGINE013 indicates that there is an issue with the hierarchy of objects in the context of the SAP Configuration Management (COM) module. Specifically, the error message states that the object type specified only allows a strict hierarchy, meaning that the structure of the objects does not conform to the expected hierarchical relationships.
  Cause:
  The error typically arises due to one of the following reasons:
  
  Incorrect Hierarchical Structure: The object you are trying to create or modify does not fit into the defined hierarchy. For example, you may be trying to assign a child object to a parent that is not allowed by the hierarchy rules.
  Data Integrity Issues: There may be inconsistencies in the data that violate the strict hierarchy rules.
  Configuration Errors: The configuration settings for the object types may not be set up correctly, leading to violations of the hierarchy.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Hierarchical Structure:
  
  Review the hierarchy of the objects involved. Ensure that the parent-child relationships conform to the defined structure.
  Use transaction codes like COM_HIERARCHY or COM_OBJECT to visualize and analyze the hierarchy.
  
  
  
  Validate Object Types:
  
  Ensure that the object types you are working with are compatible and that you are not trying to create a relationship that is not allowed.
  Check the configuration settings for the object types in the relevant customizing transactions.
  
  
  
  Data Consistency Check:
  
  Run consistency checks to identify any data integrity issues. You can use transaction codes like COM_DML_CHECK to perform these checks.
  Correct any inconsistencies found in the data.
  
  
  
  Review Configuration Settings:
  
  If you have access to the configuration settings, review the settings for the object types to ensure they are correctly defined.
  Make adjustments as necessary to allow for the correct hierarchy.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidelines on the object types and their hierarchical relationships.
