• What is the cause and solution for SAP error message SDDL_PARSER_MSG264 - Siblings Order By expression is mandatory ?

  The SAP error message SDDL_PARSER_MSG264 indicates that there is an issue with the "Order By" expression in a query related to siblings in a hierarchical structure. This typically occurs in the context of SAP applications that utilize the SAP Data Dictionary or similar data structures where hierarchical data is being processed.
  Cause:
  The error arises when a query or data retrieval operation involving sibling nodes in a hierarchy does not specify an "Order By" clause. In hierarchical data structures, siblings are nodes that share the same parent. To ensure that the data is returned in a consistent and predictable order, an "Order By" clause is required.
  Solution:
  To resolve this error, you need to modify the query or data retrieval operation to include an "Order By" expression. Here are the steps you can take:
  
  
  Identify the Query: Locate the query or data retrieval operation that is causing the error. This could be in a custom report, a data extraction process, or a configuration setting.
  
  
  Add Order By Clause: Modify the query to include an "Order By" clause that specifies how the sibling nodes should be ordered. For example, if you are querying a table of organizational units, you might want to order by the name or ID of the units.
  Example SQL-like syntax:
  SELECT * FROM your_table
  WHERE parent_id = :parent_id
  ORDER BY sibling_column;
  
  
  Test the Changes: After making the changes, test the query to ensure that it executes without errors and returns the expected results.
  
  
  Review Documentation: If you are unsure about the correct syntax or the fields to use in the "Order By" clause, refer to the SAP documentation or the data model documentation for guidance.
