• What is the cause and solution for SAP error message W8098 - Syntax '()' is only possible for elements of the container ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  W8098 Syntax '()' is only possible for elements of the container
  
  Cause:
  This warning occurs when you use parentheses () to access an element in an internal table or structure, but the syntax is incorrect because:
  
  You are trying to use () on a data object that is not a table or a container type.
  The parentheses () syntax is only valid for table elements or container elements (like internal tables or certain container types).
  For example, using wa() where wa is a work area (structure) instead of an internal table will trigger this warning.
  Or using () on a simple variable or structure field that is not a table.
  
  
  Explanation:
  In ABAP, the parentheses () are used to specify an index or key when accessing an element of an internal table or container. For example:
  itab(1)   " Access first row of internal table itab
  If you try to use () on a non-table variable, the syntax is invalid and SAP issues this warning.
  
  Example that causes W8098:
  DATA: wa TYPE mara.
  
  wa(1) = 'X'.  " Invalid: wa is a structure, not a table
  
  Correct usage:
  DATA: itab TYPE TABLE OF mara,
        wa   TYPE mara.
  
  wa = itab(1).  " Correct: accessing first row of internal table itab
  Or if you want to assign a value to a field in a structure, you do not use ():
  wa-matnr = '123456'.  " Correct
  
  Solution:
  
  Check the variable on which you are using ().
  Ensure that () is only used on internal tables or container types.
  If you want to access a field of a structure, use the - operator (component selector), not ().
  If you want to access an element of an internal table, use () with the correct index or key.

  Difference between structures and internal tables:
  
  Structures are single records with fields accessed by -. Internal tables are collections of records accessed by ().
