• What is the cause and solution for SAP error message SDDL_PARSER_MSG353 - ORPHANS cannot be combined with temporal hierarchies ?

  The SAP error message SDDL_PARSER_MSG353 indicates that there is an issue with the configuration of your data model, specifically regarding the use of "orphan" nodes in combination with temporal hierarchies. This error typically arises in the context of SAP's data modeling tools, such as SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  The error occurs because:
  
  Orphan Nodes: These are nodes in a hierarchy that do not have a parent node. In a typical hierarchy, every node (except the root) should have a parent.
  Temporal Hierarchies: These are hierarchies that are time-dependent, meaning they change over time based on certain conditions or attributes.
  
  The combination of orphan nodes and temporal hierarchies is not allowed because the system cannot determine the correct relationships and time-based changes for nodes that do not have a defined parent.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Hierarchy Structure:
  
  Check the hierarchy structure in your data model. Ensure that all nodes have the appropriate parent-child relationships.
  If you have orphan nodes, determine if they should be linked to a parent node.
  
  
  
  Modify Orphan Nodes:
  
  If orphan nodes are necessary for your model, consider restructuring your hierarchy to include them as children of a valid parent node.
  Alternatively, if the orphan nodes are not needed, you can remove them from the hierarchy.
  
  
  
  Check Temporal Hierarchy Settings:
  
  Ensure that the settings for your temporal hierarchy are correctly configured. If you are using temporal attributes, make sure that all nodes comply with the temporal hierarchy rules.
  
  
  
  Testing:
  
  After making the necessary changes, test the hierarchy to ensure that it functions correctly without generating the error.
  
  
  
  Documentation and Support:
  
  Refer to SAP documentation for more details on hierarchy configurations and temporal hierarchies.
  If the issue persists, consider reaching out to SAP support for further assistance.
