What causes this issue?

Through the pushbutton "Constant", you have inserted a constant of a
suitable type into the formula. However, at this position in the
formula, no type-suitable constant can be used because either no type
is defined or a type with a <DS:DE.CONVEXIT>conversion exit</> is
expected.

How to fix this error?

Instead of the constant, enter a character string or a number.

• What is the cause and solution for SAP error message SFB528 - No constant can be used here ?

  The SAP error message SFB528 "No constant can be used here" typically occurs in ABAP programming when you are trying to use a constant in a context where it is not allowed. This can happen in various scenarios, such as when defining a variable, using a constant in a place where a variable is expected, or in certain expressions.
  Cause:
  
  Incorrect Context: You may be trying to use a constant in a place where a variable is expected, such as in a loop or a conditional statement.
  Data Type Mismatch: The constant may not match the expected data type in the context where it is being used.
  Scope Issues: The constant may not be defined in the scope where you are trying to use it.
  
  Solution:
  
  Check Context: Review the line of code where the error occurs and ensure that you are using the constant in an appropriate context. If a variable is expected, consider using a variable instead of a constant.
  Data Type Verification: Ensure that the constant you are using matches the expected data type. If necessary, convert the constant to the appropriate type.
  Scope Check: Make sure that the constant is defined in the correct scope. If it is defined in a different program or function module, ensure that it is accessible in the current context.
  Use of Constants: If you need to use a constant, ensure that it is declared properly using the CONSTANTS statement and that it is being used in a valid context.
