Forecast reduction in MD04

I am trying to understand exactly what requirements are reducing my Forecast in MD04. We are using VSFB and have consumption Mode 2 (Backwards / Forwards), Mixed MRP = 1, consumption indicator 3 (Consume customer reqmts, reserv., dependent reqmts), and consumption indicator 1 (Consume planning with assembly). We have set Bwd consumption period 20 days, and Fwd consumption period 10 days, but when adjusting these settings and refresh the MD04 screen I cannot see exactly what is included / excluded from the reduction. Please see the screenshots for more detail. If anyone can explain exactly what, and how these numbers are being reduced it would be a great help. I have some offline data that mimics the MD04 screen data, and I need to understand how to reduce the forecast in this data to match the corresponding VSFB lines in MD04.
The VSFB requirements are a weekly forecast split into weekly buckets.
Any help would be greatly appreciated - If you require any more information just let me know. Thanks

Hi Lan,
Are you using the planning strategy 70 Planning at assembly level?
In strategy 70, the forecast for the components is not consumed by sales orders, but is consumed by either dependent requirements from the planned orders from the parent, or the reservations of the production orders from the parent. So, for the consumption to be shown at the component level, you must first run MRP at the parent, and then the component.
Please run the MRP and check the results
Normally whenever we use planning at assembly level strategy Fert or higher level should consume the requirement this is possible if u use mixed indicator 1.
Please refer the SAP help link and OSS note
SAP Library - Demand Management (PP-MP-DEM)
496480 - Planning consumption during subassembly planning

Forecast Reduction

Hello,
We delete old forecast and uploads new forecast weekly.
Forecast consumption logic is from 7 days in the past until 7 days in the future.
As far as I know, forecast reduction on next week's(Wk23) forecast resulting from current week's(Wk22) shipment will still reduce fresh forecast for next week(Wk23).
Is my understanding correct?
If we don't want next weeks' (Wk23) forecast to be reduced after the fresh forecast is uploaded, should foreward forecast consumption period be set zero?
Can you suggest options we can look at and the best one we should consider first?
Thanks a lot in advance!
best regards,
Jun

Just want to share the answer to my query that reduction of new forecast with existing witrhdrawal quantity is standard SAP behavior and below are options that can be taken if we do not want new forecast to be reduced.
- See modification Note 144513.
- If you are using the BAPI_REQUIREMENTS_CHANGE BAPI, the
NO_WITHDR import parameter is available as of ECC 5.0.
Closing this. Thanks!

Forecast quantities in MD04

Hi ,
For finished material i used MRP type, VV - forecast based planning and executed the forecast.
The MRP type has "MRP Ind Forecast = Total requirements.
All the forecast qty's are seen in MD04.
Can we control that only specific period forecast qty's are seen in MD04.
Regards
ShankarR

No. It makes more sense to work with SOP and do forecasting there. Then you can copy to DM only specific periods.

Sale order not consuming sale forecast

Dear Gurus,
I have created a sale forecast using T-code MD81, 'CusReq" is reflected in MD04...I conduct a planning run and planned orders are generated and subsequent process orders and this stock is now credited to WH stock... But the "CusReq" is not disappearing from MD04, as a result of which When I am creating a sale order Using VA01, it is only showing available qty in WH as remainder after the MD81 Requirement...
How can I make the sale order consume the sale forecast (CIR) that was created using MD81.??
Regards
Sri.

Hi,
Customer Indepnedent requirement is a sales order as treated by MRP.
The sales order consumption works with PIR not with Customer requirements.
Further in most cases, consumption means not PIR reduction.
it is consuming the planned orders created for PIR's by allocating to sales orders.
For ex; in a MTS scenario,
PIR ---1000
PLanned order 1000
Sales order 1500
After MRP
PIR--1000
PLanned order 1000
Planned order 500
Sales order 1500
PIR reduction from MD04 happens when GI happens for the sales order or GR for Production order depending the Planning strategy.

How to cancel Forecast in Production Planning

Dear Sappers,
I've a forecast for 100 quantities which is available in MD04.
If I receive delivery order for 80 quantities, in MD04 I get the requirement as 80 against delivery order and 20 against forecast.
My requirement is to cancel forecast quantities in MD04 once I receive the delivery order.
Thanks
PKB

Hi,
I'm not sure what you mean by forecast; is it PIR? or material forecast.
If you say that sales orders consume "forecast", my guess is that you mean PIR, with a planning strategy like 40.
In case of PIR, you can use a standard transaction to delete unconsumed planning -- MD74.

What is "WITHDRAWAL:" and "ALLOCATED" in Forecast tab in RRP3

Hello Gurus,
The quantity and date in withdrawal and allocated in forecast tab of RRP3 does not match with MB51 of ECC,
also pls clarify exactly how it is determined.
Regards.

Hi there! Withdrawal and allocated quantities distinguish between two concepts - forecast consumption and forecast reduction. The withdrawal quantity represents the amount of forecast which has been "reduced" and the allocated quantity represents the amount of forecast which has been "consumed". Consumption becomes reduction when a sales order / delivery is PGI'd. Or, when an SO is canceled, the consumption is simply reversed and no reduction occurs.
Forecast reduction prevents "over-planning" for a given time period, meaning that the system "remembers" how much was shipped out to the customer so that the forecast shows in the system as "fulfilled".
For example, consider a day which has a forecast of 10. There are open sales orders of 5, and another 3 were ordered and shipped today. Assume also that there is no forward/backward consumption. SO's consume forecast for the same day only. In this case, the allocated quantity would be 5 - for the currently open orders. The withdrawal quantity would be 3. And the remaining unconsumed forecast for the day would be 2.
Not sure why there may be inconsistencies with ECC, however. If you give more specifics on the nature of the discrepancy, I will try to respond with some additional input.

FM : For reduction of PIR forecast quantity

Hi.
Is there any FM for reduction of PIR <Forecast> quantity for consumption mode forward/backward>

Dear,
Please note that with stg 70, PIR will get reduced when you get dependent requirementa nd not on issue of material.
I hope you must have changed the std setting.
example
PIR for 100 for assembly
After running MRP
PIR -100
Planned order +100
Now you have run MRP for final product, which gave the dependent requirement to assembly of say 75.
Then in MD04 you will see following entry
PIR -25
Dep req from final assembly -75
Planned order +100
This is nothing to do with consumption with 261/201.
pl simulate the above scenario and come back

Reduction of Forecast in SNP

Hello everyone,
We are facing an issue in handling reduction (Consumption of forecast after PGI of a Sales Order PGI) in APO for a unique business scenario. I would like to check with experts in SDN community about their experience of handling below scenario.
Business scenario and settings:
We use MRP strategy 10, with consumption mode 2 and backward and forward consumption periods. This enables consumption of forecast based on Sales order PGIs.
We release forecast from DP monthly bucket to Weekly buckets in SNP.
STEP 1
DP Monthly CDP     100
                                 W1      W2     W3    W4
SNP weekly FCST      25        25      25       25   -   (If we do PGI of 60, beginning of week 1),
Reduction will be         25       25      10
[Remaining Consensus Demand Plan (CDP) will be 40]
Above Scenario will translate into DP_SCHED table as three entries.
              Reduction       CDP
                 25                  25
                 25                  25
                 25                  10
STEP 2
We have business process of adjusting forecast in current month as well using a KF called "Off cycle adjustments"
Say the new DP Monthly CDP is 80 -> (An off-cycle entry of -20 will reduce initial CDP of 100 to 80)
                                W1 W2    W3    W4
SNP weekly FCST     20    20      20     20   -> (Now if the same PGI of 60 stays),
Reduction will be        25    25     10
Remaining Forecast that APO shows will 30, Where as in reality it is just 20.
Even after above changes, the entries will remain same in DP_SCHED table as three entries (DP head is constant)
              Reduction       CDP
                 25                  25
                 25                  25
                 25                  10
PGI reduction seems to be one time call as soon as PGI happens /Reversals happen based on /SAPAPO/CIF_IRQ_REDUCT_INBOUND.
SAP response is that Forecast changes in SNP for reduction using PGI will create inconsistences and SAP does not support it
Any suggestions on handling such scenarios will be appreciated.
Thanks in anticipation.

Yes, this is a scenario that SAP does not support and unfortunately cannot support I remember that I have provided such reply to my customer ... (Maybe the reply mentioned in this post ... )
I'm interested to hear some ideas from our external consultant

Demand is not getting updated in MD04

Hi Team,
we are facing strange issue for an particular plant.
Issue :-In MD04 forecast is not getting reduced after doing PGI.
For this MTO scenario when we are creating outbound delivery requirement of quantity is getting generated in MD04 but after doing PGI it is not reducing the forecast however overall stock availability is reduced .
Reduction of forecast is necessary otherwise in next MRP run, additional demand would be place on the supplying plant.
Any pointers what could be the reason of forecasting not getting updated.

Dharmesh

hi,
this is to inform you that,
please check STRATEGY group in MRP views in MMR.
explain your process of how requriment will be passed to MRP.
please confirm.

Forecasting Based planning, consider incoming Sales orders, Consume PIR's

Hello Guys:
I am in real Problem about this one: I am implementing forecast-based MRP for our client which is a trading company: buys, keeps in storage and sells goods (R/3 ECC 6). We are using material forecast on a monthly period, and run MRP on a weekly period since POs are to be created weekly (therefore we also use the "Splitting indicator" to split monthly forecast values to weekly requirements)
The way MRP calculates future stocks in this situation (MRP type VV) is like this:
Current stock
+ Open POs to arrive
- Forecast Requirement
= Future stock
The problem with that one is that if there is an SD order or delivery in the future, SAP does not count in that one as well. It is a real problem, just imagine that in two weeks we have a forecast of 10 pieces of a material. SAP will propose Preqs based on this 10 piece consumption, even if we have an SD sales order for that week on 30 pieces. (by the way the SD order is in the list of MD05 but SAP does not count in that one for future stock reductions).
If I modify the MRP type in customizing OMDQ, I can make SAP to count in real consumptions (sales orders) in the future stocks: I set "MRP procedure" to PD (MRP) or "R1" (Time-phased materials planning). In this case MRP calculates like this:
Current stock
+ Open POs to arrive
- Forecast Requirement
- Real future requirements (sales orders)
= Future stock
So in this case SAP will recommend double quantities to purchase: once for the forecast reqs and on the other hand for the real sales orders.
It is a trap, SAP should reduce the forecast requirements with the real requirements. The really bad news is that there is a switch for this in OMDQ for the MRP types called "Reduce forecast" but it is not working: I have tried all the combinations of codes in the frame "Use forecast for MRP" but it can only decrease req for the current month and only on a timely basis code "2" for MRP procedure "PD" or "R1".
Thanks for Help.

Hi Mario:
I am using MRP type PD , Running the forecast using MP30 which generate the forecast requirement.
I go to MD61 , I Slected Material Forecast option and Copied the forecast requirements as planned independent requirement,
AFter that when i run MD02 and go to MD04 Screen.
System Displays MRP Element: UnPlrq----Forecast quantity --1000
MRP Element VSF for Planned Independent requirement -1000.
Based upon historical consumption data , if there ia requirement of 1000pc , system is proposing 2000 pcs to buy.
Is there any config setting i need to change so that system won't double the requirement quanitities?
Please clarify
Sweth.

Forecast delivery schedules incorrect cumulative release quantity.

Hi Gurus,
We implemented the standard LZM - Scheduling agreement with delivery orders solution for component suppliers.
The entire SAP standard configuration activated and the functionality is working correct.
u2022     Scheduling agreement type LZM / Item category LZMA / Schedule line category L2
u2022     Order Type TAM / / Item category TAMA / Schedule line category CP
Example:
Scheduling agreement forecast delivery schedule for 1000 units./ Md04 show SchAgr of 1000 units
Delivery order for 250 units (MD04 Shows Order for 250 units and SchAgr for 750 Units)
Created delivery for the order (MD04 shows Deliv. For 250 units SchAgr for 750 Units)
Goods issue the delivery / MD04 shows the SchAgr for 750 units.
*Issue:*
When we update the Cumulative quantity received by the customer it is summing up with the forecast quantity (double counting the shipped quantity).
When the Cumulative quantity received by the customer updated to remove the in-transit quantity, the forecast is adding by 250 units and   MD04 shows SchAgr for 1000 units.
Thanks & Regards
Suresh

Hi Suresh
The *** issued qty gets updated when the PGI for the delivery happens. There is a field called *** received by customer and it gets updated when customer sends the *** back in the 830 or 862 as the case may be.
The difference between the *** issued and the *** recieved is always shown in transit.
If you do not want the schedule line to be opened up, then in *** recd change it to the *** issued or ideal option is populate the last delivery PGI'd on the delivery number field next to *** recd field. Hope this helps and let me know if you need any more informataion
Regards

Forecast delivery schedules and JIT deliveries

Hi Gurus,
Got a question on sales scheduling agreements schedule lines. Our customer sends 10 weeks of forecast delivery schedules and 2 weeks of JIT deliveries. which one of these two are passed to MD04?
Assuming only forecast delivery schedules are seen in MD04:
Assuming customer sends forecast delivery schedule for week2 as 50. but in JIT deliveries he only sent 40 for that week. if only forecast deliveries are see in md04, then my forecast and planning quantity is 50 , but actually my JIT delivery is only 40. AM I producing 10 extra? that means my planning is wrong?

925,
so in system it will show on 3/21 monday
I guess this means that you are entering using a Day format rather than Week format.
You have answered you own question already. If the online SAP help, which you have read and reasonably paraphrased, is not clear enough to make you understand this, I cannot help you.
JIT horizon is 3/23, Forecast is for 3/21.
As I stated before, even though it may in your mind represent a week's demand, it is still for one day. There is no bucketing, nor time-based disaggregation, nor consumption. It is just a scheduling agreement.
You wrote
am using MRP indicator D. that means within jit horizon, consider my jit quanity for requirements. and after jit horizon consider my forecast delivery schedules as requirements.
. This is a reasonable paraphrase of the SAP online help. Do you believe this?
Forecast schedule is for 3/21. NOT for W 12/2011. This is before the JIT horizon, isn't it? What do you think will happen to the forecast schedule, looking at the last 'rules' you just wrote? and as stated in the SAP help that you read?
Now you want to enter JIT schedules. 21/22/23/24/25/26. JIT horizon is 23. 24/25/26 are after JIT horizon. What do you think will happen, based on the 'rules' you just wrote?
I feel my time is being wasted when you keep asking me these questions, already having the answers explicitly stated in SAP oinline help. Since you do not have access to a system, this cannot be a support issue, it is a evidently a matter of idle curiosity for you. I therefore believe I will will move onto other forum questions, where there is a possibility that the questioners will get some business benefit from my answers.

Forecast delivery schdule and JIT delivery schedule difference

Hi All,
What isthe difference between Forecast delivery schdule and JIT delivery schedule in JIT scheduling agreement (LZJ)??
I am doing JIT Inbound process now. Is it necesary to update both the schedule lines(Forecast delivery schedule&JIT delivery schedule)??
Thanks,
Anbazhagan E

Hello,
Forecast Schedule updates your planning , i.e. in MD04 you could see system is planning for quantities updated in forecast schedule.
