MRP Control File
Enter appropriate values in the MRP Control File (23.24).
MRP Planning Horizon. Enter the period of time, in calendar days,
which MRP should plan. MRP calculations ignore data outside this
time period. The horizon should be at least one day longer than the
longest item cumulative lead time in the database.
If you change the MRP planning horizon, impacted items are not
automatically replanned when you run net change MRP. Ensure that
all items are replanned by running MRP in regenerative mode.
MRP/DRP Combined. Enter Yes to indicate that MRP planned items
can be planned using DRP functions. Enter No if they can only be
planned using MRP functions.
Summary Default. Specify the day of the week used by all MRP
summary reports and inquiries when displaying item requirements
summarized by week.
Order Release Horizon. Enter the number of calendar days before a
planned order’s release date that the Release Due For action
message should appear on.
The order release horizon should be based on your normal paperwork
lead time and how often you run MRP. For example, if you run MRP
weekly, you should set the order release horizon to at least seven
days. If you run MRP daily, you can set it to zero.
