• What is the cause and solution for SAP error message AQ720 - A symbol can only be assigned to a symbol field ?

  The SAP error message AQ720, which states "A symbol can only be assigned to a symbol field," typically occurs in the context of SAP's ABAP programming environment, particularly when dealing with symbolic fields in your code.
  Cause:
  This error arises when there is an attempt to assign a value that is not a symbol to a field that is defined to hold a symbol. In ABAP, a symbol field is expected to contain a symbolic representation (like a variable or a constant) rather than a literal value or a different data type.
  Solution:
  To resolve this error, you should check the following:
  
  
  Data Type Compatibility: Ensure that the value you are trying to assign to the symbol field is indeed a symbol. If you are trying to assign a literal or a different data type, you will need to convert it to a symbol or change the field definition to accept the data type you are trying to assign.
  
  
  Field Definition: Review the definition of the field where the assignment is being made. Make sure that it is defined as a symbol field if you intend to assign a symbol to it.
  
  
  Code Review: Look at the specific line of code that is causing the error. Check for any typos or logical errors that might lead to an incorrect assignment.
  
  
  Use of Constants: If you are trying to assign a constant value, ensure that it is defined correctly as a constant symbol.
  
  
  Debugging: If the error is not immediately clear, use debugging tools to step through the code and inspect the values being assigned to the symbol field.
