MPL_ALLREDUCE within OpenIFS: CALL

CALL MPL_ALLREDUCE(shortwave_local,'SUM',ldreprod=.FALSE.,CDSTRING='AWICOUPLING:') |
I use the function as it is used in many other places within OpenIFS. Does it work only for 1-d variables and returns in the input variable? Did I missunderstand misunderstand something here? I'll be using normal MPI_ALLREDUCE for now but I'd still like to learn.
Cheers,
