i did some preliminary testing, and found that the Planned delivery time on the MRP2 tab of the material master controls the Delivery date on an STO, but nothing updates availability (seen on MD04) when goods issue is done from the origin plant, even though the GI is done in advance of the planned GI date and so arrival will be earlier than planned. I tested setting the Planned delivery time to 10 days and that made the Delivery date on my STO become 2/1. I checked in MD04 and the available date at the receiving plant was 2/2 (after GR date of 1 day). I then posted goods issue today, but the available date in MD04 stayed at 2/2. I would expect that the system would now estimate arrival on 1/27 (today plus 5) somehow, but dont know if this capability exists and, if it does, what is required to turn it on/make it work.
solutions appreciated.
