MRP type & planning time fence

Hello.
When I enter MRP type at MM01, error message comes up;
"The MRP type requires you to specify a planning time fence."
This check is not necessary for us.
Please teach me how to deactive this check.
Thank you in advance.
Emma S

Thank you for your reply.
To Vijay
I can't use PD because we run MRP on this material.
I want to know how to prevent these MRP type from requiring Time fence.
To Maria Nunez
Firming type of the MRP type is set "0(Planning results not firmed)".
Both ex-R/3 (Enterprise) and new R/3 (ECC 6.0) are set same.
But only ECC 6.0 requiring Time fence.
Any other customise affects??
To R.Brahmankar
This errror message (M3/097) is not set at transaction code OCHS, OMT4 and OMCQ.
If it was set, I would change the message type...
Thank you and regard.

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?

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.

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 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

Planning time fence and MRP question

Good morning,
We have the following requirement:-
1. We want the Planning time fence to move once a week (by 1 week)
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

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 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.

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,

MD04 - Planning time fence for materials that are planned externally

Hi,
I have to develop a report in R/3 which will pick up values from MD04 (for a particular material/plant combination) and show the output in ALV grid of materials which are not planned in R/3 but APO.
It should also show the planning time fence.
For example, if i goto MD04 in R/3 and enter a material-plant combination which has MRP type X0 (external planning), it doesnt show me the planning time fence.
This value/row has to be picked up from APO.
Any idea how to go about it and what are the Function Modules I should use or is there any alternative for this ?
Regards,
Anand.

Hello Anand,
Try looking at user exit in MD04 that can change the values in MD04. Then, check for material-plant type of the order. If it is X0, call RFC to APO function module to read the information you want.
I have develop before a report in R/3 that read the correct time of an order in APO to be displayed in R/3.

MF50 : Planning table and planning time fence

HI,
I use the transaction MF50 as planning table ( in order to do my MPS planning), I use "set firming date" to fix a firming date.
Now, I want o know if it should possible to reveal a message when we create a planned order within the firming date??
Thanks for your answer.

Hi,
For clarity , I am describing below the functionlity of Set Firming date is explained as below:
By setting Manual Firming date , we extend the planning time fence.
If a planning time fence has been created for a material then the following applies:
If the manual firming date lies before the end of the planning time fence, the planning time fence is still valid.
If the manual firming date lies after the end of the planning time fence, the planning time fence is extended until this date.
All order proposals with availability dates that lie before the end of the planning time fence of the manually extended planning fence are firmed for the planning run, if the materials have an MRP type which contains firming type or firming type 1 or 2
The system does not automatically firm order proposals for materials that have an MRP type with firming type 3 or 4, even if their availability dates lie before the end of the planning time fence or manually extended planning time fence.
Please check if this helps you.
Regards
Datta

Firmimg the orders and planning time fence

Hi, Pls explain about firming and non-firming and planning time fence while running mrp or mps?what is meant by firming the orders? i do not know how it work and how can we interpret the reults? pls explain with one example.

Firming: When an order is firmed , indicates that the Order no longer needs to be planned in MRP.
Order gets firmed, when we change plannde order manually and save .
Planning time fence: the time period during which if any Order comes it gets firmed subject the Compatible MRP type.
Depedning on whether they need to be firmed or not and when a new requirement is creatd in the planning horizon, How the receipt needs to be planned within the Planning time fence or out side is controlled in the MRP type.

Ratan

Planning time fence vs total lead time

Hi Gurus,
we have a scenario like the below in the unconstrained plan. Trying to understand various dates on the PWB. could you please explain.
1. Item is a Make item and it's planning time fence attribute is set as Total Lead time.
2. Processing lead time of the item is 25 and fixed lead time is 2
3. ASCP is suggesting a planned order on PTF date which is exactly 25 days from now.
4. But the suggested start date of the order is only 2 days less than the suggested due date. This is the point we are not able to understand. We have set the processing lead time as 25 so, isn't the planned order not supposed to have the start date as today?
Thanks
Mahesh

Dear,
Please refer this link,
[Planning time Fence|Planning time fence]
For sales order will convert to a specific production order use CO08 here define order type as ZP04.
OPKP ( Production Scheduling Profile) whether ZP04 is assigned under Order Type or not.If not maintain the same and then assign the same Production Scheduling Profile in Material Master in Work Scheduling view.
Also in In OPPQ or OPPR you have to define order type as ZP04 under conversation indicator use when in MRP run MD50.
Please try and come back

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

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.

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?
Best Regards,
