consumption according to forecast date

Hi,

We are on ERP R12.2.4 .

the normal behavior of consumption process in ASCP is that consumption first moves backwards according to sales order line schedule date looking for a forecast quantity to consume.

If that search is unsuccessful, consumption moves forward .

the problem is our sales order schedule date are not stable and it is hard to control backwards and forwards days in consumption options

so is there a way to make consumption according to forecast date instead , or how can we control it ?
