Run MDM_CLNT_EXTR in background

Hello,

I want to run MDM_CLNT_EXTR in night batch with a delta variant but I don't know how to call it in background.

The aim :

- run MDM_CLNT_EXTR to generate CREMDM04 idoc (outbound)

- send the CREMDM04 idoc to SAP PI

Any idea will be very helpful.

Thanks a lot.
