Master Schedule Item - Action Proposals

We have turnkey finished good items that are MS items with MS Demand since they are directly forecasted.  The issue is when these items are purchased, they do not get action messages like MRP items do - MRP Action Proposals.

For example - we will order the MS item based off demand.  When the demand changes and the delivery date may need to be advanced, pushed out or if there is no more demand it would need to be canceled, we do not see these messages.

We see Early Order, Late Order or Remove order in MRP Action Proposals and would like to see the same messages for MS items.  Maybe there is a different way to set up these items so they are not MS and we can forecast them and see the MRP Action Proposals?  We are in IFS Cloud

Hi ​@ztaayoung,

 

Did you check the below page after the MS run?

This shows the messages that are quire similar to the the MRP generated messages

 

The detailed descriptions about these messages could be found here.

https://docs.ifs.com/ifsclouddocs/24r1//default.htm?searchpage=page/MsActionProposals/List

 

I believe you can still keep your parts are MS handled parts and refer to this place to get the messages you are expecting to see.

Hi ​@Tharindu Illangasinghe  Thank you for your response.  Yes, I have looked into the MS Action Proposals, however these messages do not give me what I am looking for.  When I have MS items on a purchase order I need to have specifically the same messages telling me if an item has a message of Early Order, Late Order or Remove order, along with the MRP Due Date like in MRP Action Proposals.  Does a forecasted item have to be a master schedule item?

Hi ​@ztaayoung,

 

If you wish MRP to plan for the MS parts then you need to use the below value in the setting. This means MS proposals do not create supplies. For actual demands of MS-handled parts, supplies will be generated by MRP/PMRP. 

 

As a result, when you run the MRP it will plan for this part, and yes the messages too will be there.

 

However, I suggest you to re-look at your planning and make this decision. In this change, just to get the MRP Messages you are making a change in the planning method (MRP over MS) applicable to this part.

@Tharindu Illangasinghe - I have tried this adjustment as well.  When I make the adjustment to the Create S/P Req field to set it as Create S/P from MRP then all my demand disappears from the IPAP screen.  It leaves only the Purchase Orders which MRP Action Proposals tells me to Remove Orders since it shows no demand.  One difference I see from your screenshot is that we forecast by Customer and your screenshot shows Forecast By Part - I do not believe this would impact what we are looking at though.  I am not sure what other settings on the MS Level 1 Part you have that I may not have which is causing the demand to disappear.

Hi ​@ztaayoung,

 

What are the demands you are not seeing ?

I actually didn’t enable any other special settings.  Apart from what was given by default (refer the image below).

@Tharindu Illangasinghe - all of the unconsumed future forecast is not taken into account in the IPAP screen.  All that is shown on the IPAP screen is the supply, no demand.  Further below is a screenshot of the forecast from the Master Schedule by Part screen.

@ztaayoung when using the setting “Create S/P from MRP” the Unconsumed Forecasts are not shown as demands in IPAP. The only explanation I could find was;

  • Create S/P from MRP: MS proposals do not create supplies. For actual demands of MS-handled parts, supplies will be generated by MRP/PMRP. However, the component demands will not be exploded for these parent MRP/PMRP requisitions. Instead, the component demands are generated from the parent MS proposals.

@Tharindu Illangasinghe - the MS handled parts are turnkey parts for us.  They do not have a Product Structure/BOM with components to generate demands against.  Since the demand/forecast is in the MS part - I think this is the issue that MRP does not generate supply against the MS demand, therefore it also does not create the MRP Action Proposals either and this is what I am trying to find a solution to.

Hi,

Let us go back to the initial question in this conversation.

MRP is really really supporting the chase strategy. If demand increases tomorrow 5th January, MRP has no problem in saying “move the confirmed Purchase Order supply with due date mid February to today”. MRP does not move the PO Line, but it counts that you do it. It does not create any PO Req with due date today. This is good and bad. If you know MRP mechanics and how to interpret the action messages it is usually not a problem. Someway you handle it, right?

When it comes to MS we also have the forecast, unconsumed forecast, actual demand, demand timefence and planning timefence which complicates the picture for: “just make MS action message work the same way as MRP - how difficult could that be?!?!”

We have said: inside PTF - planner is king, outside PTF - MS Level 1 calculation is king.

And you don’t get new system generated Master Production Schedule Receipts inside PTF (nor Purchase Requisition/Shop Order Requisitions either)

As an example: let say we have a purchase order, with due date somewhere between the time fences perfectly planned for an actual demand. Now that demand is moved later… but new demands may still come in earlier. Should we really create an action message “Early Order”? Considering the time fence policy. I mean we are in the “slushy zone”. One of the benefits with MS is that you can create a less nervous system. On the other hand with MRP you have a super agile system.

Without elaborating too much about technical details I still think it would be good to be able to use:

  • The Late Order message logic from MRP
  • Planning method G  (not as simple to “just do it as it works in MRP” since we have the timefences in MS)
  • But not Early Order and Remove Order messages

Cheers,

Mats
