UPF086
- Variable &1 must have the type of a field to be changed ?The SAP error message UPF086 indicates that a variable in your ABAP program or report is being used in a context where it is expected to be a field that can be changed, but it is not defined as such. This typically occurs when you are trying to modify a variable that is not declared as a field or is not of a compatible type.
Cause:
- Variable Declaration: The variable in question is declared in a way that does not allow it to be changed. For example, it might be declared as a constant or as a type that does not support modification.
- Data Type Mismatch: The variable may be of a type that is not compatible with the operation you are trying to perform. For instance, if you are trying to assign a value to a variable that is not a field or is a read-only type.
- Context of Use: The variable is being used in a context (like a loop or a function) where it is expected to be a field that can be modified, but it is not.
Solution:
- Check Variable Declaration: Ensure that the variable is declared correctly. If it needs to be changed, it should be declared as a data type that allows modification (e.g., a standard data type or a reference to a field).
DATA: lv_variable TYPE your_data_type.
- Change Data Type: If the variable is declared as a constant or a type that does not allow changes, consider changing its declaration to a mutable type.
- Review Context: Look at where and how the variable is being used. Ensure that it is being used in a context that allows for modification. For example, if you are trying to modify a field in a structure, ensure that the structure is defined correctly and that you are referencing the field properly.
- Use Field Symbols: If you need to work with dynamic fields, consider using field symbols or references that can point to fields that can be modified.
FIELD-SYMBOLS: <fs_variable> TYPE any. ASSIGN your_field TO <fs_variable>.
