Infor LX & BPCS Tip of the Week: MPS vs. MRP

What items should be MPS planned, and what items should be MRP planned…

Master Scheduled Items are those items that are finished goods, or service items, that receive their requirements either specifically from Independent demand, or both Dependent and Independent demand.

  • Independent Demand is demand that cannot be calculated from higher level demand in the product structure, and therefore must be either a forecast or an actual customer order (Finished Goods or Service parts sold to customers).
  • Dependent demand is derived from higher level demand in the product structure. Dependent demand includes components, raw materials, and sub-assemblies. (these are not normally Master Scheduled Items).
  • Service Parts may have both independent demand from forecast and/or customer orders, as well as dependent demand from higher level demand if that item is also used in other sub-assemblies or products.
  • Cumulative Lead Time is a concept used in Master Production Scheduling (MPS) that combines the “fixed” lead time, and the “variable” lead time needed to produce the product. It is the longest path through a given Bill-of-material. Based on the MPS setup options, Infor/ERP LX will calculate cumulative lead time (also called “the Critical Path”) for you (use the “indented BOM” display in BOM300 and find the item with the longest lead time “L/T”). Note: You may have to use Action 21, Line Detail, to see the “L/T” lead time for each item.

Tips:  LX | BPCS | M3

Two big sources of inefficiencies in manufacturing are paper and spreadsheets. I know that you love ‘em, but they are the cause of more problems than you probably realize. Think of how long it takes you to get paper based data into the hands of those who can do something valuable with the data. Are you capturing all of the information correctly? Timely? What about those spreadsheets? Can everyone access that information across your organization? Is that data married with all of the related data regarding your operations to give your executive and middle management the information they need when they need it?

Make your shop floor paperless and put in place systems that talk to one another and automatically pull and push data to and from your ERP so that you can look in one place for all the information you need to run your business effectively.

If you’re not doing this today, you might as well be burning money.

Ok… so you want to know the status of a specific shop order that was released two days ago.

What do you do?

It’s a sure bet that you have a manager, supervisor, or planner who can walk the floor and find the order at whatever work center it happens to be at. He/she can then answer “what operations have been completed and how many were completed?” All this requires leg work, and of course, a fair amount of time.

Now, if you have setup your BPCS master files properly, and you report transaction activity, you should be able to get those shop order statuses much faster using the SFC300 Shop Order Inquiry Screen.

At your fingertips you can see:

  • Release date & due date
  • How many hours remain in total and at each operation
  • The quantity required, what was finished and the remaining quantity
  • What components (materials) have been issued

Pretty basic information, right? Are you getting what you need to know? If not, then you may want to reexamine how your BPCS files are setup and what transactions along with their frequency are captured.
