What causes this issue?

For characteristic &V1&, you used a variable, which however, was
defined with reference to other characteristics. As a result of this, a
type incompatibility occurred, which the system cannot resolve. You can
only replace the value of a characteristic with such a variable, that
was created with reference to this characteristic.

• What is the cause and solution for SAP error message UPF130 - Variable must be of type &1 ?

  The SAP error message UPF130, which states "Variable must be of type &1," typically occurs in the context of SAP's User Parameter Framework (UPF) or when dealing with user-defined variables in ABAP programs. This error indicates that there is a type mismatch between the variable being used and the expected type defined in the system.
  Cause:
  The error is usually caused by one of the following reasons:
  
  Type Mismatch: The variable you are trying to use is not of the expected data type. For example, if the system expects a character type but you are passing a numeric type, this error will occur.
  Incorrect Variable Declaration: The variable may not be declared correctly in the ABAP program or user parameter settings.
  Data Type Changes: If the data type of a variable has been changed in the underlying data structure or table, and the program has not been updated accordingly, this error can arise.
  
  Solution:
  To resolve the UPF130 error, you can take the following steps:
  
  
  Check Variable Declaration: Ensure that the variable is declared with the correct data type. You can do this by reviewing the ABAP code or the user parameter settings where the variable is defined.
  
  
  Review Data Types: Verify the expected data type (indicated by &1 in the error message) and ensure that the variable you are using matches this type. You can check the data dictionary (SE11) for the expected type.
  
  
  Update ABAP Code: If you have identified a type mismatch, update the ABAP code to ensure that the variable is of the correct type. This may involve changing the variable declaration or converting the data type appropriately.
  
  
  Test Changes: After making the necessary changes, test the program or transaction again to ensure that the error is resolved.
  
  
  Consult Documentation: If you are unsure about the expected data types or how to declare variables correctly, refer to SAP documentation or the ABAP programming guidelines.
  
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like SE80 (Object Navigator) or SE38 (ABAP Editor) to locate and modify the relevant ABAP programs.
  SAP Notes: Check SAP Notes for any known issues or patches related to the UPF130 error.
  Debugging: If the error persists, consider using the ABAP debugger to step through the code and identify where the type mismatch is occurring.
  
  By following these steps, you should be able to identify and resolve the UPF130 error in your SAP environment.
