Forecast Reduction in IBP after PGI delivery

Hi IBP Expert,

We are wondering if we have a forecast reduction concept after PGI delivery in IBP Time Series Optimisation.

For example, we run TS optimisation everyday in calendar week time bucket.

On the beginning of the current week (Monday), the forecast for the current week is 100, there is no actual PGI delivery, so the forecast is 100 for supply planning, stock inventory is 500.

Then, on Tuesday, we have actual PGI delivery of 30, inventory also reduce to 470.

So on Wednesday, when we run TS optimisation, the expected net forecast would need to be reduced to 70 that is 100 - 30 that has been PGI.

I was wondering if this calculation is automatically done in IBP out of the box, or we would need to do this kind of calculation in IBP as pre optimisation as part of Key Figure calculation configuration.

If this is done automatically, would there be any backward/forward forecast reduction of the actual PGI deliveries similar with forecast consumption for open SO?

Thank you very much for your advice.
