Hi all,

A question on Master schedule and demand/supply behavior of customer orders with supply code shop order and shop orders related to these orders.

We are running cloud 24.2.7. 

 

I have the problem that IFS generates supply from shop orders that are created via customer orders with supply code: shop order, but the connected customer orders don't create demand in the master schedule.

This means that we have a forecast for a next month, but the supply created by the shop order connected to the customer order makes that the system tells us to create less for this month, see screenshot:

 

We drop the forecast at the start of the month. 

 

Can someone explain this logic or am I missing settings?

 

Kind regards,

 

Evert

Hi Evert,

Can you see the Customer Order Line demand in the Supply and Demand tab of the page you are highlighting? Can you see it in Inventory Part Availability page?

MS Level 1 calculation should read pegged customer order demands as well as the corresponding pegged Shop Order supplies… So I think it is a little bit strange. You need to Calculate MS Level 1 for the part so that values from Customer Order and Shop Order side are refreshed.

The customer order line, it is not marked as an abnormal demand? There is a column for that in Customer Order Line (normally it is hidden by default).

When you say: “we drop the forecast at the start of the month” - what do you mean by that?

Best Regards,

Mats


Hi Matts,

Thanks for the reply. 

No the customer order line does not display demand in the tab Supply and Demand:

Tab Supply and Demand

See below for the settings on the CO:

CO with supply code Shop order

I can see it on the Inventory Part Availability Planning:

Inventory Part Availability Planning

 

I did calculate the MS Lvl 1 part (multiple times: the Run MS - One Part as well as the Calculate  Project MS Level 1) .

It is not Abnormal Demand , see screenshot of Master Schedule by Part and Customer order lines.

Master Schedule by Part
Customer order lines

 

The dropping is a setting on the Master Schedule Level 1 Part for Forecast Consumption (Unconsumed Forecast Disposition):

Setting on Master Schedule Level 1 Part (Drop forecast crossing Demand Time Fence)

So in my initial post the forecast of september is dropped, because IFS does not recognise consumed forecast for September. But the Shop order is shown as supply. This makes that Master Schedule is skewed (it takes the supply but not the demand).

 

Kind regards,

Ooops we are talking Project Master Scheduling here… I need to dive into this a little bit more. I’ll be back. Might be a problem with the code….

Hi Mats,

 

You are right; it has to do with the project master schedule. I could reproduce this in our config environment:

 

When I have a master schedule without project it displays your suggested behaviour (CO and SO both in the plan):

Standard Inventory Master schedule
Standard Inventory Supply and Demand tab

 

When we have a project connected to the Master schedule part (and the Customer order line) it lacks the demand of that order:

Project Master Schedule

 

Project Supply and Demand tab

 

Customer order used for the test:

Customer order

This looks like a problem with the code a suggested by you :-/. What are the next steps to get this resolved? 

 

At the moment, we run the risk that not all future material requirements are covered, because currently only the supply is included in our project master schedule and not the demand.

 

Hope to hear from you.

 

Kind regards,


Evert


Hi Evert,

You should report this as a defect. You need to create a suppor case Please make sure you are mentioning that this is about Project Master Scheduling. 

The good news is that the defect is easy to correct.

***

Another thing… These master scheduled parts - are you almost always using supply code Shop Order for them? Coz in the screenshots I can see the Project MS is also generating Shop Order Requisitions.

If you really want to do make to order/assemble to order, then please consider setting the flag Create S/P Req to: Do Not Create S/P Req

If the strategy for your part is always 1-1 relation between customer order, you can also consider if you should create a fixed MS Receipt within PTF and then define a PTF of let say 5 days. Not tooo long. Well… establishing PTF is an art of its own. It is a balancing act between stability at the shop floor, or being very responsive to customer order demand changes.

Always interesting with master scheduling discussions on Friday afternoon.
