Ok.
Best practice is BR pulls the MIR batches from the backroom (stated in workbench under Logistics). Sales floor pulls the sales floor batches (stated sales floor TM core roles).
HOWEVER...... A.S.A.N.T.S
Way back in the day, the reverse logistics specialist would pull the backroom MIR's (and SWEEPS and on occasion help pull the M&M scan). The RL specialist had to know how to do pulls and other backroom processes. This was part of their learning plan, now it is not. The specialists for Electronics were responsible for pulling the sales floor MIR's. There was a specialist for books, movies and music (entertainment) and another for printers, software, TV's, DVD players, etc. (electronics). There was also a jewelry specialist that was given sales floor MIR's for jewelry and watches. Other MIR's for different depts. were given to the TL of that area, including QA's (recalls).
At the store I am at now the BR pulls from the back and the sales floor will pull the sales floor. I pull QA's before the store opens and any other MIR's that are not in electronics. If there are a lot of MIR's for electronics or if they need help and I can step away from my area I will help the sales floor pull.
