Call a rri with two infoobjects as senders to one infoobject as reciever

Hi Gurues.

I really need your help. I´m trying to do a rri but I have the following issue.

I have to pass two infoobjects as senders (0PLANT and ZWRK02) to one infoobject as reciever (ZINFMM11___F21 => it's 0PLANT infoobject in Infoset) and I couldn't do it.

I tried with most of the possible combinations on "Selection Type".

Now I have the following setting (please check the picture)

With this setting, I only get the detail of 0PLANT but not ZWRK02.

I thought of trying with a variable, but I didn't find how to implement it. Any tutotail about it, please?

I already read the links, but none explains what I need.

One mentions the Badi SMOD_RSR00004 but does not explain its operation.

Thanks
