FDT_CORE449 - Overview

• Message type: E = Error

• Message class: FDT_CORE - Formula & Derivation Tool: Core

• Message number: 449

• Message text: Data dictionary (DDIC) type &1 is controlled by switch &2 (&3)

What causes this issue?

The system has detected that the availability of data dictionary type
&v1& to which the current data object is bound is controlled by switch
&v2&. The switch is currently turned on, so the bound dictionary type is
available.
The purpose of this message is to make you aware that although the data
object binding is OK in the current system, it is possible that problems
arise when the containing application is transported into a system where
switch &v2& is turned off. In that case, any attempt to use the data
object will lead to an exception because the underlying data dictionary
type &v1& is not available in such a system.

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 all BRFplus functions using structure &v1& can be called
only if switch &v3& is on.
