What program/file triggers a refresh of MPS ?

Does anybody know what function causes a refresh of MPS from Forecast? For
example, if the user maintains a forecast item using option 13 on menu MPF,
(programs MF110 and MF114) the next time the MPS job is run, the change to
the forecast is reflected in the MPS demand. However, if someone was to DFU
the forecast file record for an item (MSP75) any change made to quantities
for the item are not reflected in the MPS demand for the item after an MPS
run.

 

Program MPF114 (F/cast maintenace) makes reference to program DB550 which I
thought set some kind of trigger in the forecast but I don't see it being
called when I maintain an item forecast. So where else does MPS get its
instructions to recalculate demand if a change to the forecast has been
made. 

 

I am trying to force MRP to perform a recalculation of MRP demand after I
have made a mass update to the F/cast file (MSP75) and it is not playing
nice which is forcing me to maintain the f/cast using option 13 on menu MPF.
