• Message class: CNV_10020 - Message class for package 10020

• Message number: 280

• Message text: Elementary relationship &1: Spec. function module &2 has wrong interface

What causes this issue?

Specific function module &V2& has been stored for single determination
for single path &V1&. However the interface is not defined correctly.

How to fix this error?

Correct the interface definition of function module &V2&. <ZH>Note that
it must be EXACTLY the same as for sample function module &V3&</>,
because internally the call is explicitly included in the coding.
<ZH>Note:</> The program for checking the interface definition compares
the definition for function module &V2& with the one for sample
function module &V3&. This is also why the interface parameters have to
have exactly the same names.
The best solution is to copy function module &V3& to the function
module you want to use.
