Hi Gurus,
I got a CTM planning logic issue which I would like to seek your help/comment.
Scenario: a sales order on 07/15 and there is a production order due on 07/16. Planning current date is 04/15 and lead time is 30 days.
After CTM planning run, system sees that 07/16 supply is too late, so CTM suggests a new planned order on 0715 to fulfill this sale order. Since it is possible to meet the demand due date with new production instead of using existing late supply.
My question is:
1. How CTM can try to use up existing supplies before creating new orders?
2. Or can we set a demand late allowance (say, 7 days) so that CTM can peg existing supply (lateness within 7 days) to demand?
Regards,
Kevin
Hi,
To fulfill your requirement...
1) You can make use of Late Demand Fulfillment either in global setting for CTM or it can be productlocation specific.
2) You can also make use of search strategy to decide the sequence of considering supply categories in CTM profile.

1. We had max lateness allowance setting already. But the issue is that this is a global setting, some of the demands cannot be delayed at all but some can. If you look at i2 SCP, FP, they all provide the function to set demand latesness for each demand.
2. This does not work. CTM will always take due date as 1st priority. When 1st category of supply such as firmed orders cannot meet due date, it will try 2nd category and so on to find the one which can fulfill due date first.
Please also go through the thread
Based on my understanding the location product specific lateness can only be used in PPDS.
Coming to the question your had,
1.)1. How CTM can try to use up existing supplies before creating new orders? --> There are BADIs in CTM like /SAPAPO/CTM_MATLOC or CTM search strategies where you can technically influence the way CTM plans for receipts. IN the former, you can deliberately put long production horizons so that CTM does not create any extra receipt, and in the second pass CTM can run in a net change mode where existing receipts and their pegging relationships are not changed. This way you through two CTM profiles you can achive what you want.
2) 2. Or can we set a demand late allowance (say, 7 days) so that CTM can peg existing supply (lateness within 7 days) to demand?
--> you can only set max earliness to be considered by SNP run of CTM. Max earliness can be potentially picked up by CTM Location Product. Late allowance is a global setting only for CTM. Now I understand different businesses within a CTM scope could potentially have different late allowance. You would want to sell the idea of using days of supply safety stock planning strategy specifically for location products that cannot have late demand fulfilment. This is a gap in SAP functionality that is yet to be filled up.
Hi,
I'm facing a similar issue:
A planned order, PP-firmed, created by previous CTM run but satifying the demand late is getting thrown outside the planning horizon as a new planned order is being created by the next CTM run and can satisfy the demand on time and the old PP-firmed Planned order becomes an excess supply.
I fail to understand why a PP-firmed order is moved in the first place. Secondly, how is the pegging relationship violated for this PP-firmed planned order. And thirdly, why is it not being considered to satisfy a demand which could have been satisfied by it on time.
Please let me know if you have encountered such an issue and suggest any remedial solution.
Thanks,
Viresh.

Hi,
I think the system will try to plan supply so that demand will be fulfilled on time. Therefore, when there is a supply which cannot meet demand on time (in your case, PP firmed order), system will then check if it is possible to start a new order which can meet demand on time. If so, it will suggest this planned order.
To solve this issue, we have to run CTM twice. In this 1st run, we exclude PPM, TL and Ext Procurement, so that only existing supplies to be used and also we hard-peg the demand and supply. In the 2nd run, we include PPM, TL and Ext Proc but plan only unpegged demands.
Hope this helps.
