How to restart processed IDoc in PI/XI

Hi, scenario is simple IDoc2IDoc.

On receiver site the Idocs are not processed and because of this they want to have the IDoc's send again from XI.

Here they are well processed.

I already tried ZRSXMB_SUPPORT_RESTART like given in one blog but with no success.

I also tried test-message in RWB 😉 but also no success.

Can anyone help please?!
