shifting from Daily to Weekly bucket capacity for a Resource for CTM planning

Hi All,

At the moment CTM run generates a lot of Planned Orders on daily basis, which is based on daily bucket capacity of the Resource.

Is it possible to make the resource capacity to be considered as weekly and accordingly CTM run would generate Planned Orders based on Weekly availability of the Resource capacity ?

Avinash,

Assuming you are planning your resources finitely, CTM will in general not overload any single bucket's capacity.

Is it possible to make the resource capacity to be considered as weekly and accordingly CTM run would generate Planned Orders based on Weekly availability of the Resource capacity ?

Yes.   Assuming SNP:

Hi DB,

This did not changed anything. System still considers capacity for daily bucket, and hence Planned Orders divided based daily availability for the capacity.

System still considers capacity for daily bucket, 

No, this is not true.  This is how one establishes SNP Bucketed Resources with a period of 'weekly'.

Orders divided based daily availability for the capacity.

That may or may not be true. There are many factors that can influence the size of the supply elements.

Hi DB,

I understand that, but here it seems like Number and quantity of Planned Orders is being governed by Capacity availability.

If I do changes in number of periods within a Bucket, system accordingly adjusts the quantity and number of Planned Orders.

Example, when number of periods is 7 days: we get more number of Planned Orders  and less quantity for daily.

When number of periods is 5 days: we get less number of Planned orders and more quantity daily.

Avinash,

That fact tells me very little.  Well, I guess it does mean that you have probably successfully achieved capacity consumption.

What are the Master data settings in your CTM profile?

What does the resource consumption look like for this resource in your SNP planning book?  Are you fully constrained? 

Are there any other resources in the PDS for this product?

Are there any other consumptions for this resource besides this product?

Do you intend to answer expert Kishor's question?

Hi DB,

Here is a screen shot master data setting in CTM:

PDS has got just one activity having this Resource.
Planning book looks normal for the Resource, Yes Resource is being used for other Products as well.

Either I am missing something, or it is just not supported by CTM without an enhancement.

Avinash,

I asked are there other Resources in the PDS, not are there other activities for this resource.  The bucket settings of ALL resources in the planned order will affect the scheduling of the entire planned order.

What are the lot size settings in the product master?

Are there any components in the BOM?  Scheduling of the bom components can affect the scheduling of your planned orders.

Hi DB49,


PDS has got just one Resource and no components. We are using Lot-For-Lot procedure.

I do not see what is missing in this case.

Oops, I just noticed from your configuration that you are using PPMs and not PDSs.  My bad!

Please describe a bit of detail in your PPM.  How many operations?  How many modes?

Have you defined any min or max intervals in your PPM?

Have you defined any fixed durations?

Hi DB49,

Nope ! your assumption was correct, we are working with PDSs and not PPMs. I guess setting in Global Customizing gets overwritten by setting from Material Master, which in this case is: 5"PDS".

Hi DB49,

However, after performing some tests. I was able to manage the situation by increasing the Mode duration from 1 to 5 days for the activity.

Now Planned Orders span over a week and consume the relevant capacity.

However, this also means that even for 1 quantity of demand, Planned Orders are going to span for a week. Which I think is not a good idea.

Avinash,

It never dawned on me that you were talking about planned orders with a duration of < 1 week.

So, let me understand the business scenario you are trying to support here.

1.  You want to have capacity managed in weekly buckets.

2.  You have planned orders, which you want to actually have a duration of 1 day.

3.  You want the ability of a single planned order to have the ability to consume up to an entire week's capacity.

I am trying to force my brain to conceive of how this would work in real life on a production floor.  I start working on an order on Monday, I complete the order on Tuesday, and I have somehow consumed the entire week's capacity.  Is this what you intend?

Hi DB49,

Requirement is quite simple:

Present situation:

SO is 6000 qty.

Capacity available is: 300 per day.

CTM run generates:

20 Planned Orders for daily.

What we are looking for:

CTM generates: Just 1 Planned Order[ of course  if the capacity is available].

Now my thinking is, because we have daily bucket capacity for the Resource, hence CTM is generating 20 Planned Orders.

Then we made the changes as we saw earlier, to include 5 days in bucket[changes done in Resource bucket capacity]. But this did not changed anything.

After further tests, turns out Mode duration with 5 days allows lesser number of Planned Orders. Which I also mentioned is not good idea as even for 1 demand quantity Planned Orders are scheduled for over the week and capacity is distributed over the week with a daily consumption of let's say 2%.

Bottom line:

Is it possible for CTM to look at capacity constraint and still generate 1 Planned Order for 1 demand. And sensibly utilize the capacity.

Avinash
