How To Fix FDT_EXPRESSIONS526 - &1 with &2 and &3 is data-dependent, runtime exception may occur

SAP Error Message - Details

• Message type: E = Error

• Message class: FDT_EXPRESSIONS - Formula & Derivation Tool: Expressions

• Message number: 526

• Message text: &1 with &2 and &3 is data-dependent, runtime exception may occur

What causes this issue?

During the check, the system has determined that the current object or
one of its referenced objects contains a mathematical operation of type
&v1&. The operands of this operation do not have the same data type, but
can be converted to a numerical data type so that the operation can be
performed.
However, the necessary type conversion is only possible for a restricted
set of values, which can only be evaluated at runtime. Therefore, at
design time, it is not possible to decide whether the operation will be
successfull at runtime or not.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Make sure that at runtime, only values that can be converted into
numerical values are passed to the object.

• What is the cause and solution for SAP error message FDT_EXPRESSIONS526 - &1 with &2 and &3 is data-dependent, runtime exception may occur ?

  The SAP error message FDT_EXPRESSIONS526 typically indicates that there is an issue with data-dependent expressions in your SAP system, particularly when using the FDT (Form Data Tool) or similar functionalities. This error suggests that the expression you are trying to evaluate is dependent on the data being processed, and there may be a runtime exception due to the nature of the data.
  Cause:
  
  Data Dependency: The expression you are using may rely on specific data that is not available or is in an unexpected format. This can lead to runtime exceptions when the system tries to evaluate the expression.
  Invalid Data Types: The data types of the fields being used in the expression may not match, leading to evaluation issues.
  Null or Empty Values: If the expression is trying to access fields that are null or empty, it can cause exceptions.
  Complex Expressions: If the expression is too complex or involves multiple conditions, it may not be handled correctly by the system.
  
  Solution:
  
  Check Data: Review the data being processed to ensure that it meets the expected criteria for the expression. Look for null or empty values and ensure that all required fields are populated.
  Validate Expression: Simplify the expression if possible. Break it down into smaller parts to identify which part is causing the issue.
  Data Types: Ensure that the data types of the fields used in the expression are compatible. You may need to cast or convert data types appropriately.
  Error Handling: Implement error handling in your expressions to manage cases where data may not be as expected. This can help prevent runtime exceptions.
  Debugging: Use debugging tools available in SAP to trace the execution of the expression and identify where it fails.
