How To Fix FDT_EXPRESSIONS109 - Check if result type of leaf node &1 is compatible with tree result type


FDT_EXPRESSIONS109 - Overview

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

  • Message number: 109

  • Message text: Check if result type of leaf node &1 is compatible with tree result type

  • Show details Hide details
  • What causes this issue?

    The result data object assigned to leaf node &v1& is bound to another
    data object. The system check cannot determine if the other object from
    which leaf node &v1& inherits its properties is compatible with the
    result data object of the tree expression.
    Such compatibility is, however, a prerequisite for proper operation of
    the search tree if multiple match mode has been turned on.

    System Response

    If the structure of the data objects assigned to the leaf node and to
    the expression do not match, a runtime error will occur when the
    expression is evaluated.

    How to fix this error?

    If multiple match mode is active for the search tree expression, make
    sure that the data object which is bound to leaf node &v1& is compatible
    with the structure of the table result data object assigned to the
    expression.

    Procedure for System Administrators

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

    Cause: Type Mismatch: The most common cause of this error is that the data type of the leaf node (e.g., a field or variable) does not match the expected data type defined for the expression tree. For example, if the expression tree expects a numeric type but the leaf node is a string, this error will occur. Incorrect Configuration: The configuration of the expression tree may be incorrect, leading to mismatched types.
