Equal splitting of PIRs

Hi Experts,

We are using flexible planning in our project to plan the sales. The plan will be for monthly quantity for each material in a plant. Once the plan is finalized, we will transfer to demand management.

The requirement is when I transfer the monthly quantities, system should split this quantity equally to weekly buckets. For example, if the monthly quantity for a mateial is 100MT, when I transfer, system should show this quantity equally split into four weeks. i.e W1: 25. W2: 25, W3: 25 & W4: 25.

I did the standard configs for automatic split in SPRO but still its not getting splitted.

Request your expert advice here.

Regards
