Just In Time Scheduling
If you install this module, you will not have to run the regular procurement scheduler anymore (but you still need to run the minimum order point rule scheduler, or for example let it run daily). All procurement orders will be processed immediately, which could in some cases entail a small performance impact.
It may also increase your stock size because products are reserved as soon as possible and the scheduler time range is not taken into account anymore. In that case, you can not use priorities any more on the different picking.
