• What is the cause and solution for SAP error message 42794 - Select structures only ?

  The SAP error message "42794 Select structures only" typically occurs when you are trying to use a data structure in a context where only structures are allowed. This error is often encountered in ABAP programming or when working with data dictionary objects.
  Cause:
  The error is triggered when:
  
  You attempt to select a table or view instead of a structure in a context that requires a structure.
  You are using a SELECT statement or a similar operation that expects a structure but receives a different type of data object (like a table or a view).
  
  Solution:
  To resolve this error, you should:
  
  
  Check the Data Object: Ensure that the data object you are trying to use is indeed a structure. If you are using a table or view, you need to change your approach to use a structure instead.
  
  
  Use the Correct Data Type: If you need to work with a table, consider defining a structure that matches the fields you need and use that structure in your SELECT statement.
  
  
  Modify the Code: If you are writing ABAP code, ensure that your SELECT statement is correctly referencing a structure. For example:
  DATA: ls_structure TYPE your_structure_type.
  SELECT SINGLE * FROM your_table INTO ls_structure.
  In this case, your_structure_type should be a defined structure type.
  
  
  Review the Context: If you are using a function module or method that requires a structure, ensure that you are passing the correct type of parameter.
  
  
  Related Information:
  
  Data Dictionary: Familiarize yourself with the SAP Data Dictionary (SE11) to understand how to define and work with structures, tables, and views.
  ABAP Documentation: Review the ABAP programming guidelines and documentation for more information on data types and structures.
  Debugging: Use the ABAP debugger to trace the execution of your program and identify where the incorrect data type is being used.
  
  By ensuring that you are using structures in the appropriate contexts and modifying your code accordingly, you should be able to resolve the error message 42794.
