Defining planning time fence and creation indicator with out oppr settings

Hi, we dont use mrp groups and accordingly i did not set oppr settings. i observed that planning time fence and the creation indicator (omdz & oppr) are defined thru mrp goups. please advise how to define those w/o oppr settings? is there any seperate settings or oppq settings for them? please advise.

Hi,
Maintain it directly in the Material Master.

Planning time fence and planning cycle

Dear Experts,
Please provide me the clarity on planning time fence and planning cycle in MRP 1 view with example as i am not able to understand the SAP definition
Regards,
Phalgun Patel

Phalgun,
Planning time fence is a standard planning concept. Here is SAP's version
http://help.sap.com/saphelp_erp60_sp/helpdata/en/92/bf029544bd11d182b40000e829fbfe/frameset.htm
Also, from SAP help
Outside of the planning time fence, procurement proposals are created as usual in the planning run. When these procurement proposals move into the planning time fence, they are firmed automatically depending on the setting of the firming type.
I don't think I explain it any more clearly.
'Planning Cycle' can refer to several different concepts. Can you quote the difinition you are finding difficult to understand?

Planning Time Fence and Rescheduling Purchase Req

How to Process the MD04 exception u201C30 Plan Process According to Scheduleu201D for Purchase Req.
Please provide me a Step by step procedure with example to Reschedule the Purchase Req with given rescheduling date.
*Really I am confused with PLANNING TIME FENCE.
What it does with Planned Order and Purchase Req ?
Based on the some of threads in SDN, I couldnu2019t come to the conclusion of the terminology behind PTF.
So could you please provide me an explanation with example will make clear idea on PTF.
Thanks in Advance.

dear friend,
as far as i know, all planned orders that lie in the planning time fence are firmed. that means that they can no longer be changed automatically by the system in the planning run in long-term planning.
outside the planning time fence, the system creates order proposals as usual according to the shortage quantity and the lot-sizing procedure. once these planned orders move into the planning time fence, they are automatically firmed depending on the how you have set the firming type.
the planning time fence can be defined per material in the material master record or via the MRP group.

Planning time fence and Lot size

Hi,
MRP type=P3, Planning time fence=28 days, lot sizs=EX and all 28 days are working days.
so today =05/112009 and i check the MD04 End of planning time fence is 03/12/2009
But when i change the lot size to =ZC(3 Months lot size) keeping the rest all same as above.
and when i check MD04 The planning time fence moved to 01/01/2010
What should be done to keep the planning time fence as 03/12/2009 and i don not want to change either MRP Type or lot size

Praveen,
I think your Lotsize Indicator is based on Planning Calendar. Please check the period definations of the planning calendar assigned to the material in the MRP2 view.

Internal Transfer, BOD, Planning Time Fence and ASCP Reschedule suggestion

Hi,
we've an ASCP plan with 5 ORG. We've many items with BOD like this one:
BOD of ITEM X:
ORG 1 BUY
ORG 2 TRANSFER FROM ORG 1
ORG 3 TRANSFER FROM ORG 1
Using this rule, we set PLANNING TIME FENCE for Buy items, at about 0,7 * LEAD TIME (from the approved supplier list) in BUY ORG (S01 in this example)
and PLANNING TIME FENCE = 0 in TRANSFER ORGANIZATION.
Sometimes, we release Internal Requisition to transfer item in excess from other organization to organization S01 to avoid Purchase Order not needed. In this case, the plan will suggest to reschedule OUT the internal requisition and if the planning time fence is large, people at the internal shipping department, will not see this Internal Req because they work in short range date.
Furthermore the ASCP plan will reschedule out all the Discrete job and planned order pegged to this suply.
This problem originate because we implement the reschedule out suggestion from ASCP over internal req ( we've a custom for this). How can ve avoid the Plan suggest to reschedule out this Internal Req? Maybe we can use the Profile "FIRM INTERNAL REQ INSIDE PLANNING TIME FENCE?".
Someone know if there are other ways?
Thanks in Adnvance.
Giacomo

Giacomo,
Usually, clients use "MRP: Firm Internal Req Transferred to OE" to keep internal requisitions from being rescheduled by ASCP. This would mean that any IR that has created an ISO would be treated as frim by ASCP. The intent is that since standard ASCP cannot reachedule ISO/IR orders, that you prevent these reschedule recommendations.
Since you have intentionally implemented a customization to cancel/reschedule these orders, this may not work for you.
The other profile option that you suggested; "MSO: Firm Requisitions Within Time Fence" was intended for purchase requisitions. It may work for internal requisitions, but you'll have to test. If it did, it would only work for the organization that is recieving the IR. You had set the PTF to zero (0) in that organization.
I suggest you try the combination of this last profile option with a PTF value that you do not want to see any reschedules.

Kevin

Planning time Fence and Firmed Planned Orders

Hi,
Withing our 30 days planning time Fence, MD04 is showing * mark against the planned order, but when we drill inside the planned order, Firming indicator is missing.
Using M1/ P1 MRP type.
1) Is this a correct oservation?
2) How does it affect the availability check, if we are considering Firmed Planned order to be included in the Av Chk. Will this planned order be considered with the Availability check?
Thnx!
Abhi.

Dear,
Let us understand with an example
MRP type = P1
Time fence = 30 days
Let say you have created 3 requirements
01.12.2007 - 100 TO
01.01.2008 - 100 TO
01.02.2008 - 100 TO
Let me know what are you expecting the syatme to do if you run MRP today?

PLANNING TIME FENCE and RELEASE TIME FENCE

Hi, I am on ver 11.5.10.5. We are using MDS and MRP here.
Trying to understand the right meaning of planning and release time fences , so that I can define the right time fences in the item attributes.
My cumulative manufacturing lead time for top assembly is 12 days. Should this be the planning time fence.(12) ?
Time taken to run MRP (1 hr) and manually release all planned orders to PO or WIP is 4 days. So should 4 days be the release time fence. Auto relase feature is not being used.
Am I on the right track here , or is the track totally missing?

James,
The Planning Time Fence is the point that you want no new planned orders to be created prior to. In MRP this was based on the suggested dock date for (buy) orders and suggested due date for (make orders). Whatever you set the value to, no new planned orders will get created earlier than date.. even in an unconstrained plan
So as a practical point, how far ahead do you want to create your WIP jobs? If you are creating WIP jobs now for next week and your build LT is 5 days, you may want to be a user define value of at least 5 days. This would put the suggested due date of the planned order on day 6 (5days + today), the suggested start date would be today. You can also add a pre-processing lead time to make the suggested order date earlier and monitor that value. I would test these, understand the attributes and the resulting dates and determine the right value.
The Oracle ASCP User Guide has a good description of lead times that you should review on page 6-90. Most of this information is the same as old MRP, but some has changed. You can also review the inventory user guide to get a description of these attributes.
If auto release is not used, the auto-release item attribute is not used.
Regards,
Kevin

Planning time fence and MRP question

Good morning,
We have the following requirement:-

2. If we have a schedule line at the end of the Planning time fence, we want this to move inside the planning time fence (as per step 1)
3. Put a fixing indicator on anything that falls into the Planning time fence (as per step 1).
Thanks in advance

Planning Time Fence Use with MRP

Hi,
I was wondering if planning time fence has use with an MRP type without a firming type. Basically, SAP says it is only used with the MRP contains a firming type. However, i thought the planning time fence is also used with SAP. For example, i can tell MRP to only plan materials outside of the planning time fence. Anyway, just looking for further insight or clarification.
Thanks, Erik

for automatic firming ,
you need to maintain a MRP type related to firming , while running MRP , system will firm the order with in the planning time fence, & based on the firming type, any new requirement system will plan according to the MRP type
Firming type 1- P1 or M1. The date of new order proposals that are actually created in the planning time fence are rescheduled out to the end of the planning time fence. Therefore, these new order proposals are not firmed.
Firming type 2- P2 or M2: The system does not create any new order proposals within the planning time fence. That is, the shortage situation is not adjusted within the planning time fence.
Firming type 3- P3 or M3: Order proposals that lie within the planning time fence are not firmed automatically. The order proposals required to cover the requirements are moved to the end of the planning time fence.
Firming type 4- P4 or M4: Within the planning time fence, the system creates no order proposals automatically. That is, the shortage situation is not adjusted within the planning time fence.
Manual firming
you can firm the planned order in MD12

Firmed planning time fence

Hi gurus,
My business scenario is to firm my planning shop flloor during 60 days.
To do it I used the planning Type P1. So If there is a requirement during these 60 days the planned orders is proposed at the end of this time fence. But this is the requirement date that is defined out the time fence. I have to begin the production (and so change the shop floor planning) during my firmed time fence of 60 days to respect the planning proposed by MRP.
Is it possible to achieve my scenario ?
Thanks.

Hello Laurent,
If I've well understood what you want :
you would keep normal run of P1 for any planned orders which cover a requirement inside the planning time fence, and in the same time, you would get new proposals from the MRP in the planning time fence if the requirement date is outside the planning time fence.
In this case, it seems me to be a bit difficult.
The planning time fence is done to take in account the procurement proposal and not the requirement level. Basically, it's firmed the production plan in a defined horizon whatever the requirements could be.
In anyway, we could imagine a specific program which runs after the MRP with these internal steps:
. selection of the planned orders which have been rejected outside the planning fence,
. filtering the selection against the requirement date (keep the date outside the planning time fence),
. changing the start date of each good planned order and firming it ( & setting an opération code ).
In my opinion, technically speaking, the bolt-on is very simple but the impacts on the MRP process has to be evaluate for the final users (understanding and maintenance). Moreover, there is the difficulty to determine the requirement origin in some context.
I hope to be helpfull,
With regards,
François-Robert NICLOT

Scheduling Agreement & Planning Time Fence

Hello,
I read a lot of articles on Planning Time Fence and the MRP Types P1 to P4 that goes with it. And I have tested it out in a Testing Environment.
But I can't get it to do what I need.
This is a normal planning with no PTF and MRP Type PD.
Sometimes we have false requirements that show up in the past due to human error. When this happens, MRP rolls during the night and adds a bunch of deliveries in the past to cover the requirement.
I wanted to use the PTF to prevent this. Meaning that extra deliveries would get added by MRP but after a PTF and not Firm deliveries. So that once the error is corrected, MRP rolls again and deleted all the extra deliveries it added.
** Only P2 and P4 adds deliveries after the PTF, but I need it to act normal on a day to day basis aswell and have MRP create deliveries like the print screen above. To add non-Firm deliveries after the PTF is just in rare cases of human error.
Not sure if my explanation is clear.
Patricia

Hi Patricia,
The planning time fence is there to stop MRP from making changes to requirements that fall within the planning time fence.
Your planning time fence is a rolling period which shifts by 1 day each day and is calculated as of the current date. Yesterdays date is passed so it would not make sense for a planning time fence to use a date in the past to start it's calculation.
Everything that falls before the end of the planning time fence will not be changed by MRP and you will see that all these schedule lines in MD04 will have an * assigned meaning they are firmed for MRP.
If you manually add schedule lines in the past, the planning time fence will not stop you from doing this. The planning time fence will only stop MRP from making changes.
By the way:
If you manually add requirements to the scheduling agreement then MRP will never change these requirements as these are fixed requirements.
If your customer would add requirements in the past or you add independent requirements in the past and your current stock does not cover the requirements the system will generate schedule lines and will put these directly after the planning time fence with an exception message assigned to them.
As a side note:
I always wonder why such questions arrive in the forum as this is something that can be very easily tested in the test environment.

Planning time fence- MRP

Hi Guys:
Can I use Planning time fence if i am using MRP type PD?
what are the settings i need to maintain for planning time fence and how it defined generally , is it a function of leadtime?
Thanks
Kodali

Hi Padmasri :
How to freeze the order proposals if i am using MRP Type PD.
Because , I might run MRP Yesteraday it might have created Planned orders or Purchase requistions and Buyer might have issued purchase order to the vendor.
today i got some more sales order and additional requirements , So when i run MRP today System propose Purchase requistions asking to change the previously created requistions on Previous Run?
Could you explain how to manage this scenarious without timing fence and still using MRP type PD?
Thanks
Kodali

Planning horizon and planning time fence

What is the meaning of terms
- planning horizon.
- planning time fence.
Where and how we can use these terms?
Kindly explain with a example.

Hi,
1. planning horizon
Net change planning in the system only plans materials that have undergone a change that is relevant to the planning run within the period which you defined as the planning horizon. The system sets the net change planning horizon indicator automatically for these materials.
In net change planning in the planning horizon, the system only plans those materials provided with the net change planning horizon indicator.
2. planning time fence
The planning time fence dictates a firm period for planning purposes. Subsequent MRP runs will not create planned orders within the time fence but will place them just outside it. Orders must be manually moved forward if desired. The idea is to create a short term period of plan stability.Check the MRP tabs on the Material Master for the planning time fence
period for the material.

Sankaran

Link Planning time fence with planning calendar

Hello,
In MD04 transaction, we can see the planning time fence lign. In my system, the planning time fence lign is calculated based on the plant calendar (SCAL transaction).
But, we will like to calculate the planning time fence based on the planning calendar (MD26 transaction) and not on the plant calendar.
I mean, when I close a period in the planning calendar (MD26), I want that the system establish the new planning time fence lign based on the planning calendar.
Does anyone know if it's possible? If yes, how should I do ?
Best regards,
Gwen

Hello Gwen
The planning time fence is always calculated according to the factory calendar defined at plant level.
If you are using a periodic lot-sizing procedure with a time fence, system may generate replenishment proposals outside the planning calendar dates, especially if you are using a goods receipt processing time. If you want to make sure that the dates will be always according to the planning calendar, you may check the following modification note:
397870
MOD:Procurmt propsls on non-dely date due to plng time fence
If you want to create your own logic to calculate the time fence, you may use the BAdI MD_MRP_PARAMETERS.

Managing planning time fence ( P1 MRP type ) and firm zone in ME32L

Hello,
I want to know if there is or are some documents to know how to manage planning time fence in MM02 and firm zone in ME32L ?
For me, in ME32L the firm zone is the firmed quantities sent to suppliers but not firmed for MRP so how to manage this easily ?
Thanks.
Romeo.

Dear,
Firm ZOne in SA, says that that much qty will be procured from that vendor with in that date specified, if not taken the production cost and cost related to that will be paid.
Now the planing time fence, is the time with in which no change is allowed. Hence if there is any new requirement to that RM, then it will be pushed to outside the time fence.
Hence if there is a schedule line which is already there and requirement is coved with in that, then your requirement is met, if not system will create a new schedule line in the trade off zone/planning zone.
I hope you got the point.
