  • What causes this issue?

    You have tried to associate the result data object field &v3& (type &V4&
    ) with field &V1& (type &V2&) that has been passed as expression
    context. However, the type of the result data object field (&V4&) is not
    compatible with the type of the underlying database field (&V2&).

    System Response

    The expression can be activated, but you must make sure that the type
    mismatch that has been detected does not cause any problems at runtime.

    How to fix this error?

    Assign the result data object to a database field of the same data type.
    The types do not have to be identical, but it must be possible for the
    system to carry out a type conversion so that the types can be matched.
    &example&
    In the expression context, you use a table with a text type field. At
    runtime, this field is mapped to a number field in another table that is
    used as result data object. In this constellation, the system makes you
    aware of the type mismatch. However, you can still decide that this is
    OK as long as you can guarantee that the text field in the context data
    object always contains a number.
