Order Related Replenishment Issue in EWM

In EWM Order related replenishment. I have open order quantity as 100 KG.

I have 3 Fixed Bin assigned as

Bin      Max Qty    Min Qty  

B01      30          10

B02      40          10 

B03      50          10

In EWM , OBD is determining Rough bin as Bin B01

On executing Replenishment in /SCWM/REPL, system is determining only B01 and creating task only for

30 Kg (Max defined for B01) .

But it should create 3 warehouse task 40 Kg from B02 and 30 Kg from B03 which is not happening.

Also if I run /SCWM/REPL again , It gives error saying No replenishment to execute but we have still 70 KG left to be replenished.

Please suggest if I am missing any setting.

Can rough bin determination  be for multiple Bins?

If yes then how?

Thanks,

Abhishek
