Dear Experts
We have DP and PPDS iplemented in our project.
We have finate planning for 4 weeks.
Forecast is released from DP to PPDS in First 2 weeks demand in Daily level and Remaining 2 weeks as weekly level.
Our Manufacturing cycle time for Finished product is 4 Seconds.
Currently we are using Following Heuristics:
Step1 Heuristic:
Stage Number Algorthm: SAP_PP_020
Step 2:
SAP_REM_002 (Multi Resource Planning)
Assuming today as Monday, when i release DP Forecast to PPDS today, the demand is released in 14 days +2weeks.
When i run PPDS Heuristics , Planned Orders are getting generated on today for all PIRs in the current week.Planned Orders are getting generated even on next monday for all PIRS of Next week.
Offcourse i accept that enough capacity is available for producing.
But in other way the stock levels are raising and Inventory Cost is increasing.
Our Users want Planned orders need to be generated before 24 hours of the Due Date.
How to make my production plan feasable as per our Users Requirments?
What changes need to be done for my existing Production Planning Model? Please give your suggessions.
Thanks
Hello KcK,
I guess the issue here is that in weekly buckets all the consolidated demand for the week is being released on the Monday of the week. PP/DS sees this as one consolidated demand and plans. You have to ensure that the demand is split in a given prioportion over the week. You can accomplish this in two ways:
1). Use the BADI /SAPAPO/SDP_RELDATA
2). Use a Daily Buckets Profile/ Period Split profile.
Apologies if I haven't understood the requirement correctly.

Hi Abhi
Thanks for your reply.
The demand is not not consolidated on Monday, The demand is available on Tuesday,wed...sunday.We are releasing demand as First 2 weeks broken down to the Daily Level and remaining 2 weeks is consolidated to weekly level.
We are using Time Bucket Profile instead of Period Split profile while releasing the DP Foprecast to the PPDS.
I feel that this issue is not related to DP Demand.
Thanks
Hi Abhishek,
................
When i run PPDS Heuristics , Planned Orders are getting generated on today for all PIRs in the current week.Planned Orders are getting generated even on next monday for all PIRS of Next week.

Do you mean all the planned orders generated on today ( to cover all PIRs in the current week), start on same date and end on the same date ? So you want all these planned orders should have staggered start-end dates, so that just 24 hrs before due date , the planned order starts ?
You are using SAP_REM_002 Heuristics profile and has time buckets profile as Week .
The demand planning is happening correctly here, as you think.

Hi Datta
Do you mean all the planned orders generated on today ( to cover all PIRs in the current week), start on same date and end on the same date ? So you want all these planned orders should have staggered start-end dates, so that just 24 hrs before due date , the planned order starts ?
Yes , All the Planned Orders are generated on Monday (Assuming today is monday and releasing the Demand on Today).hus
Example:
DP Forecast for the Current Week for MAT1:
Mon = 10000
Tues= 5000
Wed=10000
Thus=10000
Fri=5000
Sat= 5000
Output in PPDS:
Planned Orders: 45000 on Monday i(From 2 shifts)
(Our Capacity of Production is 50000 Units per Day for Mat1)
So you want all these planned orders should have staggered start-end dates, so that just 24 hrs before due date , the planned order starts ?
Yes we need it before atleast two days before because our manufacturing lead time is 4 Sec for Fin Mat.
You are using SAP_REM_002 Heuristics profile and has time buckets profile as Week .
Yes we are using SAP_REM_002 Heuristics as of now
.Different Time profiles used in PPDS :
Ours is Daily Demnd Plan and Daily Production Plan.(We have 2 shifts and 12 hrs a shift).
Example:
Production Plan on Monday: 2weeks daily(14 DAYS) + 2weeks (Aggregated to weekly level)
Tuesday: 13 days + 2weeks (Aggregated to weekly level)
Wednesday: Current week(5days)14 days2 weeks((Aggregated to weekly level)
total= 19days+weeks(aggregated weekly level)
Thusday:18days+2weeks
Fri: 17 days+2weeks
Sat: 16 Days+ 2weeks
Sunday: 15 days+2 weeks
Demand Plan:
In DP, forecast is created in Mixed Buckets:
3Weeks in Days + 49 weeks in Weekly Level
In Demand Planning while releasing the Demand to PPDS:
On Monday: 14days+2 weeks(aggregated)
On Tuesday: 13 Days+2 weeks
Wed: 19 days+2weeks
so on.. till sunday.
Awaiting for your reply..
Thanks

Hi Datta
Sorry for the late.
I tried with all options available in Strategy profile but same result.
As we have sufficient capacity, system is creating planned orders for the day1 of the week.
Manufacturing time of Finished Product is 3.5 Secs.
Any other solution for my requirement?
Regards

the problem here is.......Products are produced with 4 weeks shelf life, yet stock becomes unsalable with less then 1 week remaining shelf life. This means, production in week 1 can supply sales during week 1 to week 3, but canu2019t supply sales in week 4.
