MD61 backward-forward consumption

Hello experts,

In MD61, my client created a planned independent requirement for a material with a planning period of month.

The requirement now is that they want to implement a backward-forward consumption. Example is that in the last week (W4) of month 1 (M1), an order is created, then it should consume first all the previous weeks in M1 (backwards). Then if all planned quantity are consumed in the past, it will consume from M1-W4 to the future (forwards).

Please advice on what to do. Points will surely be awarded. Thanks in advance!

Br,
