ATP quickies

Some quick notes, all regarding the ATP process. First some tables that I had to dig for recently: //SCHEDLIN and //OBREF. In the first one we can find the first confirmed date of an order item. The second has the link between orders and deliveries.

Then OSS note 987299 that includes some major enhancements to report //SDRQCR21, namely the possibility of running in iteration mode (like the delta report), running just for a specific sales order, do the PAL check just for the open orders (no more major shift of orders between PAL buckets) and some other things. As this report is a known pain, this is good news.
