Dear Friends,
I meet a very strange case that when system generate planned order based on forecast and safety stock, some parts are missing in planned order ( in fact they are in BOM).But if I create production order manually , those missing parts are added in production order's part list.
I checked in BOM and MRP setting for those materials, can't see any special setting or lock info.
For those missing parts, we made engineering changes in BOM in Sep. of 2009,but I checked the valid date is correct, from 12.09.2010 to 31.12.9999
Pls. advise why it happened, how to solve it.
Thanks a lot in advance!
Best regards,
Tina
