• What is the cause and solution for SAP error message SDDL_PARSER_MSG058 - An alias name must be assigned for the expression (& ...) ?

  The SAP error message SDDL_PARSER_MSG058 indicates that there is an issue with an expression in your SAP system where an alias name has not been assigned. This typically occurs in the context of SAP Query or when working with ABAP code that involves data selection or manipulation.
  Cause:
  The error arises when you are trying to use an expression in a query or a report without providing an alias for that expression. In SQL and similar query languages, an alias is a temporary name that you can assign to a table or a column for the duration of a query. This is often necessary for clarity, especially when dealing with complex expressions or when the same column is used multiple times.
  Solution:
  To resolve this error, you need to ensure that every expression in your query or report has an alias assigned to it. Here are the steps you can take:
  
  
  Identify the Expression: Look at the part of your query or code that is causing the error. The error message should indicate which expression is problematic.
  
  
  Assign an Alias: Modify the expression to include an alias. For example, if your expression is something like SUM(sales_amount), you should change it to SUM(sales_amount) AS total_sales.
  
  
  Check for Multiple Uses: If the same expression is used multiple times, ensure that each instance has a unique alias to avoid confusion.
  
  
  Test the Query: After making the changes, run the query or report again to see if the error is resolved.
  
  
  Related Information:
  
  SAP Documentation: Refer to the SAP Help Portal or the specific documentation for the module you are working with for more details on query syntax and best practices.
  ABAP Development: If you are working in ABAP, familiarize yourself with the syntax for defining aliases in SELECT statements and other data manipulation commands.
  Community Forums: If you continue to face issues, consider checking SAP community forums or reaching out to SAP support for additional assistance.
  
  By ensuring that all expressions in your queries have appropriate aliases, you should be able to resolve the SDDL_PARSER_MSG058 error effectively.
