• What is the cause and solution for SAP error message ISSR_TP623 - Data object &1 cannot be assigned to field symbol &2 ?

  The SAP error message ISSR_TP623 indicates that there is an issue with assigning a data object to a field symbol in ABAP. This typically occurs when the data type of the object being assigned does not match the expected type of the field symbol.
  Cause:
  The error can arise due to several reasons:
  
  Type Mismatch: The data object you are trying to assign to the field symbol has a different data type than what the field symbol is defined to accept.
  Field Symbol Declaration: The field symbol may not be declared correctly or may not be compatible with the data object.
  Scope Issues: The data object may not be in the correct scope or may not be accessible at the point of assignment.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Data Types: Ensure that the data type of the object you are trying to assign matches the type expected by the field symbol. You can use the DESCRIBE FIELD statement to check the data type of both the data object and the field symbol.
  
  
  Field Symbol Declaration: Make sure that the field symbol is declared correctly. For example:
  FIELD-SYMBOLS: <fs_object> TYPE any.
  
  
  Use TYPE Reference: If you are dealing with complex data types or structures, consider using a type reference for the field symbol:
  FIELD-SYMBOLS: <fs_object> TYPE REF TO your_type.
  
  
  Check Assignment Logic: Review the logic where the assignment is made. Ensure that the data object is initialized and accessible at the point of assignment.
  
  
  Debugging: Use the debugger to step through the code and inspect the values and types of the variables involved in the assignment. This can help identify where the mismatch occurs.
