Lot size key HB with a planning calendar

I would like to be able to continue to use lot size key HB (replenish to maximum stock level), but with a planning calendar in order to specify Friday deliveries. However, the system does not appear to be capable of doing this. Does anyone know a way around the system limitation?
Thanks in advance!

I appreciate the suggestions. I would very much like to use a "Friday" planning calendar, however, if I changed the lot size key to PK - I can no longer replenish to a maximum stock level (unless someone knows of a way to get MRP behavior like lot size key HB but with something like PK).
I also tried using the "Planning cycle" field on the MRP 1 screen, but it appears to require time-phased planning - which again seems to rule out use of Lot size key HB.
Any other ideas?
Thanks again,
Ed

Lot size Key without splitting Quota

Hi,
Can any one explain me what is the use of Lot size Key without splitting Quota.
We had created a lot size Key - XY with following seting:-
1) Lotsize Proceed = P
2) Lotsize indicator -K
3) Scheduling =2
4) No of periods = 1
5) Splitting Quota = Not checked(blank)
If we had configured this lot size key, what is the benefits of the above setting, What testing need to be done to know whether this lot size key is working perfectly after configuration?.
Thanks in advance

Hi,
If splitting quota indicator not set, then qouta arrangement is not used during planning wrt to selected lot size.
Lot size procedure you selected, it is a periodic lot sizing procedure. Here the system groups several requirements within a time interval together to form a lot.
Lot size indicator Determines how the lot size is calculated for a certain lot-sizing procedure during material requirements planning. For your selection system creates lot size by refereing to planning calender defined in the system
Scheduling -
This indicator defines the time in the period the system is to create the availability date or the start date for the lot for period
lot-sizing procedures.
The availability date is the date on which the material, including the goods receipt processing time, is available again. In the MRP list, the availability date is equal to the MRP date.
In in-house production, the start date is the order start date, in external procurement the start date is the release date.
according to your selection - Availability date at period end
No of periods - 1
Run a complete MRP cycel to check whether it is working properly or not.
Post the results what you get.

Pavan

Fixed lot size key has no effect on planned orders generated for VC PIRu2019s

Hello gurus,
does anyone have an idea why the fixed lot size key is not having an effect on the planned orders that are generated for the Planned Independent Requirements (PIR) for MTO configurable materials. My client is using planning strategy 56.
I have copied & customized the Fixed lot size key FX to suit the MTO production (u201CLot size as in short-term periodu201D activated) that works nicely even with configurable materials when a planned order is generated for a sales order. But the planned orders in the preplanning segment, i.e. that were generated for PIR's, are still created equally to the PIR quantity.
Is this behavior an error or an SAP feature? Though, I have reviewed the OSS Note 437098 that might be related to this. Can anyone tell me if it is related to this issue?
Regards,
Mikko

Got the answer fro SAP:
Please consider the following note, which provides the explanation about this behavior of the lot-size, when VSE requirements are used:
125498 - MRP/Docu: Planning segment and lot-for-lot order quantity
The following section of the note describes your scenario in detail:
"The planned independent requirements for a material are in a separate
planning segment (planning strategy planning without final assembly,
requirements type VSE, VSEV).
You enter a rounding value or a rounding profile or an lot size that is
not exact in the material master.
Material Requirements Planning:
In Material Requirements Planning, planned orders are generated for the
planned independent requirements. The lot size settings (such as fixed
lot size or minimum lot size) are also not taken into account."

Lot size key

Hi ,
In one scenario , it is required that planned prders will be created where the req for 5- 8 days is clubed together and order date is not created on some specific day .
Will lot ize key help in this regard .
Regards
ShankarR

Hi,
Connect the planning calendar to your lot size key
First, you will need to set up the planning calendar.
Menu path: Production -> MRP -> Master Data -> Planning Calendar (MD25)
You will then need to use this planning calendar (the one you created) in the material master when planning your raw materials (MRP2 View in 4.6C - Field name : Planning Calendar).
1. When you maintain the planning calendar you will need to enter a valid from date and valid to date.
2. Your periods will also need to be set up and they will be weekly, for example:
    From Date : 11/23/2001    To Date : 11/29/2001   (11/23 is a Friday, this is your from date).
    Do this for as may weeks as you wish (say weekly for 2 years).
3. When you have set up the planning calendar, you will then need to make some changes to the weekly lot size configuration
    (WB), or you may need to create a new lot size key if you do not want to change 'WB'. Essentially, you will need to use the
    following in the lot size configuration (OMI4) :
    No. of Periods : 1
    LotSizeProced.: P
    LotSize ind : K
    Scheduling : 1

Lot Sizes Used for Fore cast planning

Dear all,
<b>For fore cast planing and Automatic reorder point planning what are the lot sizes are use full and what are the advantages and effects for each lot size procedure.</b>
I am expecting answer for this question from all of you.
Regards,
Krishna

Hi
These fore cast planing and Automatic reorder point types are consumption based planning.
Hence for these MRP types normally, lot for lot ( EX ) will be used.
You can go through the following link for further info on lot sizing procedures.

PLANNING CALENDER IN LOT SIZE

Hi
What is the function of Planning Calender in Lot Sizing procedure in SNP.

Hi
You can define the planning calendar to define the periodicity of lot size.
For example in our case we want to SNP to create requirement only in alternate month based on lot size.
So we create planning calendar which consist only alternate month and attach to lot size.
Now when we execute the SNP planning, it will create supply element only in alternate month.
I hope this will give insight of it. Please let us know , if it helps you.
Thanks

Help on Planning Calender and lot size procedure settings

Hi Gurus,
We have 2 different schedule at the moment for our PO Placing to our supplier :
1. Planning Calendar D01 --> For Seafreight shipment, PO Placing on bi-weekly basis, every Monday and RDD (Request Delivery Date) is on Thursday (11 days after PO Placing)
2. Planning Calendar D02 --> For Airfreight shipment, PO Placing on weekly basis, every Friday and RDD (Request Delivery Date) is on Wednesday (5 days after PO Placing)
Now we have required to change the SEAFREIGHT process by having the PO Placing on weekly basis, every Monday and RDD (Request Delivery Date) is on Wednesday (9 days after PO Placing).
Please let me know the step by step procedure to create a new Planning Calendar and Lot Size Procedure to accomodate this requirement?
Thanks for your help.
Regards
Brijesh

Dear Brijesh:
1. I think you are planning to change the Planning calendare D01.
2. For this go to MD26- GIVE THE plant / palnning calendar id.
3. Then in the CAlc rule for spec peroid - change the day from wednesday to Monday.
4. SAve this and generate periods.
5. Now in the maeterial master- check if you have the lot size as PK and also planning calendar as d01.
6. In the planned dleiveyr times you enter 9 days.
Kindly check this and revert back.

Planning time fence with Lot size MB

Hi Friends,
I am facing one issue as below,
I am using MRP type P3 , Planning time fence is 20 days , Lot size is MB (Monthly). I am not using MRP group.
Planning time fence should be calculated as Todays date+Planning time fence on MRP1 but if the calculated date with this formula is going in next month system takes first date of next following month as Planning time fence (effect of lot size MB).
WIth lot size EX , it works fine.
Can we avoid shifting of Planning time fence to first date of following month with lot size MB?
Thanks.
Sandeep

I got a workaround , I have used 2 lot sizing procedure in a sigle lot size. Daily lot size (for Short term) and Monthly lot size for Long term. For short term requirements are grouped for 28 days. Closing the thread. Thanks.

Lot size exclusion from planning run

Hi Gurus
My scenario is some materials are maintained with lot sizes as EX , VB, HB , when planning run executed , the system should not consider the VB and HB lot sizes ( these are not bom components) and no procurement proposal should exist , we are not following storage location MRP ,
Pl come back in full thanks in advance
Regards
Ram

Hi ramki
VB is MRP type not lot size. VB consumption based planning with manual reorder point. The planning proposal will be created based on your reorder level.
HB is lot size of " Replinishment to maximum lot size "
Normally oils and others are procured where the storage tank capacity is restricted. The max replish level will be your max tank capacity. You can define them as cosumable materials or bulk materials.

Lot for lot(EX) with minimum lot size

Hi Experts,
Is it possible to have Ex with minimum lot size. I have a situation where an FG cannot be produced over a certain qty but can be produced in any numbers beyond that. Please explain.
Regards,
Sachin

Hi,
You can use Lot size key EX- lot for Lot order and Minimum lot size as per the requirement. If the lot size is smaller than the Minimum lot size qty procurement proposals will be created for the minimum lot size quantity.
Hope it resolve your issue. Kindly revert for further clarification.
thanks and regards

Lot size EX with Minimum lot size

Hi all,
I have a query like how will the material behave if the following settings are made
MRP type:M0
Lot size:EX
Minimum lot size:100
Rounding value:100
Maximum lot size:300
My main question is is it right to use lot size EX along with mimium lot size value,rounding value,Maximum lot size defined.

Hi Anshul
Ex is lot for lot order quqntity. It will put lot size exactly what is required from MRP run. During MRP run after net requirement calculation the system will look for Lot size,Rounding value and Rounding profile before making procurement proposal.
You can use EX with Rounding value
If you requirement is 180 Nos and the rounding vaule is 100 the lot size for this will be 200.
Hope this will clear your doubt.

Rounding Value is not considered for MB lot size

Hi
I have a scenario where MB (Monthly Lot size) lot size is used with rounding value. Example as below:
Lot size: MB
Min Lot size: 15000
Rounding Value: 20000
DEMAND: 16000
When MRP run, System is creating the 16000 as P Req instead of 20000 which is the rounding value.
Pl let me know, if I need to apply OSS note / any other solution for this.
Thanks,
JK

Dear ,
Are you using any Rouding Profile in MRP1 view ?
What is the Setup in OMI4 for MB-Lot Size .Remove the tick mark in Last Lot Exat if it is marked .By specifing the rounding value, the system will determine during lot size calculation that lot size qty is a multiple of of an order unit(eg : pallet size if mtrl is delivered in entire pallets...).
Please check what is the Lot Size Indicator or Lot size procedure assinged to it ?
2.you can use rounding profiles...its used to define the setting of rounding up or rounding down the order proposal qty into deliverable quantities...rounding profile maintenance the t-code is OWD1. Here for static rounding profile
Rounding profiles are defined under:
spro-> purchasing->consumption based planning->planning->lot size calculation ->maintain rounding profiles...
it consist of threshold value and rounding value...
the threshold val is the value from which the system rounds the value of the next deliverable units upto...
the rounding value is from which the systemshd round up to as soon as threshold value is exceeded...
Otherwise , Check FM MD_ROUNDING_VALUE

'Start of Lot Size Grouping' and 'Lot Size Strategy' parameters

Hello,
For "by period" lot sizing procedure, could anyone explain the difference between:
- "Start of Lot Size Grouping" flagged with "Lot Size Strategy": 1
- "Start of Lot Size Grouping" flagged with "Lot Size Strategy": blank ?
I have played around with both options and both produced the same result. If anyone could provide some insight , I would appreciate it.
Many thanks in advance.

Hi Datta,
Thank you for your help.
You indicated that the "The first period of the grouping horizon can be different than the period in which demand exists".
How would the first period be different? What other elements could be considered for the start of the horizon?
For example,   Periodic Lot of 4 weeks, Lot Size Strategy 1 or blank and Start of Lot Sizing Group Flagged produced the exactly same result. What is interesting about it, is that with Lot Size Strategy "blank" the group production quantity is placed in a bucket where there is no demand. The results with Lot Size Strategy "1" makes sense as I have the grouped quantity placed in a bucket where I have shortage due to Safety Days requirement and not necessarily demand.
                             w1     w2     w3     w4     w5     w6         w7            w8
Total Demand     125     42     42     41          110     37     73
Production (Planned)     223                    244
Days´ Supply     58     53     48     43     58     53     48     43
Safety Days´ Supply     43     43     43     43     43     43     43     43
Any thoughts? Many thanks in advance.

Rounding value and Minimum lot size

Hi all,
Finish material is X and Raw material is Y.
Bom- For Preparing Xu2019s 1 Qty, 1 Qty of Y is required
In Material Master of Y - Rounding value and minimum lot size is 10,
Project needs 5Qty of X.
When MD51 for Project execute u2026 PR of Y must be of 10 as per rounding value and minimum lot size, but it is creating PR of 5 qty.
Above scenario working properly if I take MRP run with MD02 for material X for 10qty, after MRP PR of Y will be created for 10qty.
With Regards,
Ashish

Dear,
By default, the lot size works as lot-for-lot quantity in the make-to-order and project scenario.
Go to OMI4 select your Lot size and define Lot Size: SOP 1 or 2Lot-for-lot with rounding. Better create new Lot size as ZX with these setting.
If you always want lots to be created for the multiple of the rounding value, you must specify a minimum a multiple of the rounding value.
Example: minimum lot size: 10 and rounding 10.
Please try and come back.
