• What is the cause and solution for SAP error message ISSR_TP784 - Data object & cannot be assigned to field symbol & ?

  The SAP error message ISSR_TP784 indicates that there is an issue with data type assignment in your ABAP program. Specifically, it means that a data object cannot be assigned to a field symbol due to a mismatch in data types or structures.
  Cause:
  
  Data 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 hold.
  Structure Differences: If the data object is a structure, it may not match the structure expected by the field symbol.
  Uninitialized Field Symbol: The field symbol may not have been properly initialized or defined before the assignment.
  Scope Issues: The data object may not be in the correct scope or may not be accessible at the point of assignment.
  
  Solution:
  
  
  Check Data Types: Ensure that the data type of the object you are trying to assign matches the data type of the field symbol. You can use the DESCRIBE FIELD statement to check the data type of both.
  DATA: lv_value TYPE your_type.
  FIELD-SYMBOLS: <fs_value> TYPE your_type.
  ASSIGN lv_value TO <fs_value>.
  
  
  Define Field Symbol Correctly: Make sure that the field symbol is defined with the correct type. If you are using a structure, ensure that the field symbol is defined to point to the same structure type.
  
  
  Initialization: Ensure that the field symbol is initialized before the assignment. You can use the ASSIGN statement to initialize it properly.
  
  
  Check Scope: Verify that the data object is accessible in the scope where you are trying to assign it to the field symbol.
  
  
  Use Generic Types: If you are unsure about the data type, you can define the field symbol with a generic type (e.g., TYPE ANY), but be cautious as this may lead to runtime errors if the types are incompatible.
  
  
  Example:
  Here’s a simple example to illustrate the correct assignment:
  DATA: lv_value TYPE i.
  FIELD-SYMBOLS: <fs_value> TYPE i.
  
  lv_value = 10.
  ASSIGN lv_value TO <fs_value>.
  
  IF sy-subrc = 0.
    WRITE: / 'Value assigned:', <fs_value>.
  ELSE.
    WRITE: / 'Assignment failed'.
  ENDIF.
  Related Information:
  
  ABAP Documentation: Refer to the official SAP ABAP documentation for more details on field symbols and data types.
  Debugging: Use the debugger to inspect the types of the variables involved in the assignment to identify mismatches.
  SAP Community: Engage with the SAP Community forums for additional insights and solutions from other developers who may have encountered similar issues.
  
  By following these steps, you should be able to resolve the ISSR_TP784 error in your SAP ABAP program.
