Still having zero luck achieving the following (for IFS apps 8):

generating purchase requisitions (NOT MS Supply lines, actual requisitions) based on ALL of the following:

MS Unconsumed forecasts

Safety Stock

Min/max/multiple lot sizes

Lead times

As soon as any min/max/multiple are set, requisitions revert to MS Supply lines on MS level 1 run.

MRP will use min/max/multiple and safety stock to generate requisitions but will ignore forecast and only plan on actual demand.
