How to suppress / hide warning messages in SUBMIT statement

Dear forumers,

With a SUBMIT statement below, how may I suppress / hide warning messages that are issued from the program, RM07MLBD?

SUBMIT rm07mlbd USING SELECTION-SCREEN 1000

     WITH matnr    IN s_matnr

     WITH werks    IN s_werks

     WITH bwart    IN s_bwart

     WITH datum    IN s_datum

     WITH lgbst    EQ c_true

     WITH bwbst    EQ ''

     WITH sbbst    EQ ''

     WITH pa_sumfl EQ c_true

     AND RETURN.

Appreciate any inputs or help here at all. Much thanks.

P/S:

Example of the warning message issued: message M7391
