Dependent Demand Quantity is to high

Hi All,
This proble is SNP PDS related.
We have an issue on a product in that we have Finished Product which has a component. The Finished product to component ratio is clearly 1:4 (one finished product requires 4 of a certain component). However when we look at the dependent demands it is calculating them way to high in fact 1:8.7. So for the dependent demand its calculating we need 8.7 components for 1 finished product.
Does anyone have any idea what could be causing this?

Hi Sandeep,
Thank you for taking the time to help me with this issue.
I tried this on Friday and made these steps:
1) Use Interactive Supply Network Planning to copy to an external Excel file the production plans
2) Deleted the current plans in Interactive Supply Network Planning
3) Deleted the PDS in APO
4) Used Curto_Create to resend the PDS into APO
5) Opened up the Excel file and pasted the production plans back into Interactive Supply Network Planning
6) Process complete
At the end of this process, it still had the same problem unfortunatly.

Supply Chain Planner Work Bench: Dependent Demand Quantity in Horizontal Pl

Hi,
Does any one have idea on how to calculate 'Dependent Demand Quantity' in Supply Chain Planner's work bench.
(in Horizontal Plan)
This is dependent (component)demand quantity amount for a given item(Finished good or Assembly).
Navigation:
Application: Advanced Supply Chain Planner
Supply Chain: Supply Chain work Bench (select this)
(select org)
Plan--> (select any plan)--->current recommendations-->(select org again)-->select item --> select horizontal plan in right side screen-->then u see Dependent Quantity.
I need the formulate to calculate this.
Any help is appreciated.
Thanks,
Srikanth Ramaraju

Dependendent Demand for a component can represent the Discrete Job Demand and Planned Order demand (from the parent). If the component's final assembly has a discrete that is open and any planned orders against it, all of this demand is summed up in dependent demand at the component level. You can see the detail once you query the supply/demand from the workbench for the item prior to going to the horizontal plan.
hope this helps!

Dependent demand requirements distributed in days

Dear experts,
Planned Orders created by the PPDS planning are usually between 2 to 4 days long, normally longer than one day. For some components we would need to see the requirements distributed proportionally in days instead of receiving the total depend demand quantity just before the beginning of the order. Reason for that is because suppliers are geographically very close so these components are ordered in daily basis and also, these components are actually being continuously issued to the mixing tank.
P.e:
Planned Order = 2000 PC --> Availab.Date = 4th July 12:00 am (starts 2nd July 12:00)
Component Requirements = 2000 PC -- total quantity required at the beginning of the order --> 2nd July 12:00
The business requirement is to have the requirements distributed proportionally by days:
2nd July --> 500 PC (Order is half of the half)
3rd July --> 1000 PC (Order runs the whole day)
4th July --> 500 PC (Order runs half a day)
I have tested with the Distribution Key assigned into the Production Version and also to the components. I have tried distribution with both distribution function: equal distribution and equal portions (alternatives dispatch at the start and end date do not work for my requirement), and then also the distribution type according to discrete points. Nevertheless I only get continual consumption which is not bad but with regard to the components dependent demand dates it is not what I need, the entire quantity is at the start of the operation to which components are assigned.
Any experience with this kind of requirement?
Thanks for your advice
Regards
Carlos

Hi Santosh,
Thanks for the answer. I have been using distribution key GLEI and as you mentioned, I got 3 lines in the Stock/Req List for the finish good (1000 PCs per day) in R/3 and therefore I got 3 dependent requirements in R/3. However, in APO I get only a planned order, 3 days lenght, so there is only one dependent demand for the component which requirement date is just before the beginning of the planned order. Then, material planners see the total demand for the order in one day even though the order takes 3 days and the total quantity is not needed at the beginning.
This is have I did:
-GLEI assigned to the component and to the Production Version
-Transfer the PDS
-I have the C for Continual Consumption assigned to the finish article and also for the components the PDS.
-I ran Planning of Standard Lots considering Continous I/O (however in R/3 I get the 3 lineas even creating the order manually or with the normal planning with standard lots.
In APO, I dont see any distribution of the quantity in the planned order,and neither in the dependent demand. I get a 3000 PC planned with availability day one day (one line) and the same for the dependent demand, one line. What I can see on the DSPB, chart product stock, is that the component is being required continuously and the planned order quantity is growing also gradually.
Am I missing something? It must be possible in APO also!
Thanks again
Carlos

Dependent Demand Distribution

Dear PPDS experts,
I am facing problem with distribution key . I have updated the Distribution key GLEI (Equal distribution) in Production version and the same has been updated in the BOM component. When I run product Heuristics in the PPDS system is creating one planned order in APO and Respective dependent demand. When that Planned order moved to ECC system, because of the Distribution key it is splitting the order quantity in the planned order duration equally, but it is not splitting the dependent demand of the Component.
I would like to know is there any prerequisites/ settings for the component to the dependent demand split. Your suggestions are highly appreciated.

Hi Tiago,
Thanks a lot for your reply ... I tried this but for one componet dependent requirements are not distributed , but it is working fine with the header material . I will check further and update you ..

How to manage different supply parameters for the same item based on demand quantity?

We are using unconstrained ASCP. We have some products that can be produced in a 'small' machine or can be produced in a large tank. If ASCP has created a planned order for a quantity less than 1000 it will be made on the small machine with the supply quantity = demand quantity. For example, we have a demand of 250, we will make exactly 250 on the small machine. But if the demand quantity is greater than 1000 we will make the supply in the tank with a fixed order quantity of 1590. Financially it will cost us less to do this and scrap the difference because the small machine is very expensive to run compared to the tank.
The challenge is, say we need 1200. ASCP generates a planned order for 1200 and all the dependent demands support 1200. Now we want to make 1590 and we are short of materials. This assumes we have set the item with no supply parameters. On the other hand, if we set a fixed order quantity of 1590 but only need 100 then we we have to scrap the materials for the balance due to a short shelf life.
Any ideas how to set a supply quantity using different parameters based on the demand quantity?
Mark Madal

Hi Mark,
I personally don’t see any standard solution for this requirement especially with an unconstrained plan.
However, if it is feasible, you can try below solution with a 'constrained plan with decision rules enabled' and check if it works,
1.   1. Define two different items – Item A and Item B
2.   2. Item A uses small machine in its routing and can have any demand that is below 999. So, Max order quantity = 999.
3.   3. Item B uses Large Tank in its routing and is a substitute of item A. Also, fixed order quantity = 1590.
4.   4. Define component substitution relationship between A and B. A and B will have identical BOM.
In a constrained plan with decision rules enabled, optimization logic will ensure that planned orders are generated for Item A whenever there is demand below 999. And for Item A, supply will always be equal to demand quantity. When the demand is more than 999, optimization engine will select substitute item B and will generated fixed supply of 1590 for it.
Check if this satisfies your requirement.

CTM and Dependent Demand purchase Requisitions

Hello Gurus,
We have a business situation where there are 2 plants which can produce a finished product from a single input product. It is much less expensive for us to transport the finished product than the input product. We want CTM to force the plant with the supply of input product to produce the product and send it if that plant has capacity - only transporting the input product to the demand plant if there is no capacity at the supply plant.
Plant A Demand 100 units of Product X
Plant B Supply of 100 units of Product Y which can be used to create Product O
PPMs for creation of Product at both plants.
Desired outcome:
If Plant B has open capacity to create Product X prior to due date, Plant B creates Supply of Product X from Product Y and transports Product X.
If Plant B does not have open capacity to create Product X prior to due date, Plant B sends Product Y to Plant A which creates Product X.
The supply may be at Plant A or Plant B so the scenario must be able to work in either direction.
Currently, when CTM runs, it see the demand at Plant B and creates a planned order there, creating a purchase Requisition for the dependent demand.
Is there a solution for this?
Many thanks in advance,
Sarah

I have done some further testing of the system and have found that I can further clarify my question.
consider 3 production plants situated roughly in a line with PLANTA located 1000 KM east of PLANTB and PLANTB located 500 KM east of PLANTC. Because PLANTC is nearer to PLANTB, the transportation lane procurement priority for PLANTC to PLANTB is lower than PLANTA to PLANTB (making PLANTC the first to be considered at a procurement source for PLANTB)
We have demand for a finished product at PLANTB. We can create the finished material at PLANTA or PLANTC. PLANTA has the input material in stock for creating the finished material.
When CTM makes its planning run, it looks at the PLANTB demand and determines that PLANTC is the correct procurement source for the finished material. It looks for the finished material at PLANTC and can't find it, so it creates a Planned Order to create the finished material. In order to do that, it pulls dependent demand from PLANTA.
The result is that we are moving input material west 1500 KM to PLANTC and then moving the finished material east 500 KM to PLANTB.
We have set our priority for moving input material very high, so it should be the last resort to move.
It appears that CTM is looking at the priority of the finished material only when determining procurement source. Is there any setting I can make to the system so that it will look at both the dependent demand priority and the finished material priority when determining procurement source?
Alternately, is there a way to mark the ATP group EB as not being available during a specific CTM run (without removing the dependent material from the TLANE)?
Ideallly, we'd like to be able to move the dependent material to another plant if the capacity at the plant it is currently in is too full.
thanks in advance for any advice,
Sarah

Background job not automatically poopulating Dependant Demand

Hi Users,
We've recently set up a POS & PA using the DP-BOM selection and characteristics, manually created PPM's and generated CVC's using the BOMS. All of this is set up fine in our SCM 7.0.
The background job has created the forecasts for the ouptput products but NOT the input product.
Now if I call up the parent material, and then choose to show the input products the dependant demand is generated. If I now return to the material with the dependant demand, it now shows the demand from the parent.
Or, if the forecast is genereated interactively, then the dependant demand is poopulated.
Is there an automated method to populate the dependant demand when using background jobs? I would like to think that we don't have to query every sales BOM parent in DP and drill into the input products to load the dependant demand?
Please let me know if there is an easier way to do this as part of the background processing.
Thanks
Edited by: Paul_111 on Mar 31, 2011 4:20 PM

Hi Andand,
Thanks for your reply and sorry if my post is confusing.
As far as the PPM with imputs A & B, output C - I have this relationship working and calcuclating demand in DP no problems.
If I now add a new PPM combination inpput X, Y and output Z. Create the BOM CVC and TSO so its all set to go. Add to selection profiles and background jobs.
Now, if I run the background job to create the forecast and this runs successfully. Now I check my products.
Z has the forecast generated, X & Z have no dependant demand showing.
The only way I've found that pushes the demand to X & Z is:
- open product Z in demand planning and then choose the option to show input products from the header
OR - from demand planning, select the univariate forecast to run interactively.
My issue:
The background job (if run alone) does not push the forecast on Z to X & Y.
And if I show the input products or create forecast (as bove) the dependat demand is shown on X & Y.
This is going to be a slow process if we have to do this everytime we run the backgound job.
What am I missing when running the background job?

BAPI_MOSRVAPS_SAVEMULTI3 creating unwanted Dependent Demand

We are using the BAPI function BAPI_MOSRVAPS_SAVEMULTI3
to create Production Orders to integrate WIP from a
legacy system. The presence of PDS for the product on which the production order is created, makes the PDS assignment to the production order. But, it is also creating a depenedent demand for the component in PDS, which inturn pegs to the supply on the component. We dont want the dependent demand to be created and peg to the supply, as the supply is already reduced in the external system.
We tried using PLANNING_MODE_USAGE parameter, but was not able to stop the creation of dependent demand.
Any way around this?

Hi,
Do you need the PDS in the planning system (APO) at all in case you don't want to see the dependant demand. The BAPI
BAPI_MOSRVAPS_SAVEMULTI3 documentation says:
For you to be able to create an order, a valid source of supply must exist for in-house production. This can be a production process model (PPM) of the type PP/DS or a production data structure (PDS). The source of supply is then used to generate the order. The order structure (components, operations, durations, capacity requirements, and so on) is determined based on the explosion. If a valid source of supply does not exist, a 'dummy' activity is generated and the order is created without structure and with only a main component.
We create production orders with dummy activities and only the output component using the BAPI without having the PPMs at the supply plant.
Regards
Vinod
NB: Also try 'Deactivate Dynamic Pegging' option in the product-supply location master data in the 'Demands' tab to ensure the dependant demand does not peg to available supplies of the component.

Dependent Demand not genarated

Hi Experts,
My client product structure starts from 1*****, 2***** and so on to 7****** that is we have 6 level BOM. Final FG is 1*** and 7*** is raw material. 1 will be procured from vendor1 by providing component 2 to vendor1. 2 will be procured from vendor 2 by providing component3 to vendor2 and so on. 7*** material is a standard procurement. So we are implementing sub-con scenario in SNP using SCM 7.0. So we created work centers and PPMs at sub-con locations (location type 1011 as only one product from one plant will procure from sub-con locations).
Could any one confirm the following master data settings I made
1) Both FG and Components procurement type will be 'F' (External procurement) at plant. Where as at sub-con locations FG will be 'E' (In-house) and component will be 'F'.
2) Transportation lane with sub-contracting defined for finished good between sub-con location to plant. Transportation lane between plant to the same sub-con location defined for the component with sub-contracting (not sure whether it should sub-contracting or standard procurement in the transportation lane) as we are using PPM
With those settings I ran CTM and no PRs are generated. Where as when I ran SNP01 I got PRs only one 1 series and I didnt seen any dependent demand. I ran low-level code before running SNP01.
Could any one guide me to get the PRs through CTM.
Thanks,
Naveen

Hi Experts,
For the master-data set-up in SNP, I got the following low level codes.
SNP Low Level Code     Material     Location
0          100057     Plant1
1          100057     Sub-Con1

6          306574     Plant1
7          306574     Sub-Con3
8          506083     Sub-Con3

10          506083     Plant2
11          506083     Sub-Con4
12          600004     Sub-Con4
13          600004     Plant2
14          600004     Sub-Con5
15          700002     Sub-Con5
16          700002     Plant2
Still I am not able to genarate the dependent demand. My Integration models for Storage Location stock and vendor stock active and no issues with those material ids.
Could any one give some in-sight.
Thanks,

Dependent demand in CTM

Hi :
I have a problem when i am creating a demand for FG , dependent demand for component is not getting generated .
I checked following :
PPM exist
Master data selection is right
Please suggest what else can be the reason .
Dependent demand is being generated for one other product using same profile

Hi,
Assuming that planned order for finished good is getting created , would liekt o suggest ...
1) Check with heuristic and also with infinite CTM if dependent demand is getting generated.If yes then no major problem with master data set up.
2) Also go for "Check CTM Master Data" in CTM profile. You may get some clue there. Its available in Edit option in CTM profile.

CTM - Forecast Consumption for Dependent Demand

Hi
We have a scenario where the Planning Strategy for a assembly part (say X) is set to a custom copy of 70 so that forecast is consumed by dependent demand. Forecasts are released from DP for such assemblies.
The Parent of this assembly (say A) is defined when sales order is taken (Engineer-To-Order scenario) and BOM defined with X under it. The Finished Good 'A' itself may have any other planning strategy (say Make-To-Stock or Make-To-Order).
The problem we are seeing is that when system plans for X during a CTM run, the system adds the the dependent demand of the parent to the forecast of X itself. There is no forecast consumption, so this leads to doubling up of demand.
I understand that forecast consumption occurs in Livecache and CTM does not store the intermediate results of planning in Livecache as orders, so there is no forecast consumption.
Any suggestions on how forecast consumption of dependent demand can be achieved during the CTM run ?
Thanks
Rishi Menon

Hi,
Request you to go thru the CTM help library under topic sub assembly planning to resolve your issue..
It says you need to carryout two CTM runs.
In the first CTM planning run, you plan the sales orders, and in the second CTM planning run that you then execute immediately afterwards, you plan the planned independent demands of the assembly.

Dependent demand flow from SCM to ECC

Hi ,
Can any one explain, how the scm dependent demand can flow form scm to ECC.
scenerio-
I have 5 level of BOM , i need to plan up to 3 level in SCM and other needs to plan MRP in ECC.
Is it possible to transfer the dependent demand of 4rth level in ECC form SCM and run the MRP?
BOM are PDS explosion not RPM matrix.
Regards
Lav Mishra

Yes it is very much possible. MRP type should be X0 for material planned in APO and PD for not planned in APO.
X0- Means without MRP with BOM explosion so if you are transfering publishing planning results of APO planned material in ECC it will explode bom to plan ECC planned product in MRP.

BAPI- To Pick DEpendent Demand in APO

Hi All,
I am working in APO-ABAP.I Am Using a Bapi to Get The Dependent demand for a Product.Bapi is BAPI_MOSRVAPS_GETLIST2.But this is not picking the same for ATPCAT-AU,AV,AX,EL,AY,AZ.Does anyone know any other BAPI to pick the same.Urgent
regards
Ahasan

Dear Ashok
Your requirement can be met using DP BOM. I am not sure about parent child CVC's , but DP - BOM should work.
You need to first create and activate PPM/ PDS for DP with usage D (BOM Demand Planning).
Assign it to model and create a planning object structure with DP BOM relevant.
Create the master and CVC based on MPOS
Create a PA with 2 different KF( one for finished product, another for dependent BOM). Initilize the PA and version.
Config the forecast settings for PA.
