for my FG's material master, i have maintained in MRP2 tab, inhouse production time = 19, and GR processing time = 10. when i ran MRP with Scheduling parameter = 1, the system scheduled my planned order as : Order Finish : 10/02/2008
Order Start: 7/18/2008
Planned Opn: 07/18/2008
Avail for Plan.: 10/16/2008
If in-house prod time is 19, shouldn't this be, 9/5/2008? what may have caused this?
