Lot Size OMI4

Hi Team,
Can anyone guide me to understand the importance of the below highlighted fields in OMI4 with some exmaple? I am reading the F4 help but i can not understand it.
Thanks

Hi Sugan,
If the help is not enough, I recommend to make an individual test in your sandbox to understand what is the meaning of each parameter.
For example, you ask about the meaning of Last lot exact. This is what the help says:
Controls whether the last lot is planned exactly in the whole plannning
horizon, and not according to the settings for the lot-sizing procedure or for
the rounding value/rounding profile.
When you select this field, the quantity available is zero at the end of the
net requirements segment and the gross requirements planning segment in the MRP
list and the stock/requirements list.
This means that you only procure what is needed. This avoids remaining stocks
and, when applicable, high scrapping costs, but the remaining requirements are
covered by the last lot. This is useful for discontinued materials.
So this what you can do if you want to understand the help. Imagine that you have a code with minimum lot size and rounding equal to 500 CS.
This is the MRP result using lot size MB:
As you can see at the end of the product life (once there is no more demand, you will see that you have a remaining quantity.. cause because you had monthly lot size and rounding qty = 500 CS.
Imagine that you copy lot size MB in a new lot size Z2, but you flag the parameter: "Last lot exact". So the only difference between MB and Z2 will be the Last lot exact flag. You run the MRP and this is the result using Z2:
Note that there is no remaining qty. So as is mentioned in the help, this helps to avoid remaining quantities at the end of the product life.
You can follow the same approach to understand each of the other fields if the help is not enough.
Thanks and Regards,
Mariano

Lot size creation in PP

Hi gurus,
I have 2 scenarios,
1. PIR of a product X is 56 & lot size is 10. After running MRP, SAP should create 6 plan orders of qty 10.
2. PIR of a product X is 54 & lot size is 10. After running MRP, SAP should create 5 plan orders of qty 10.
Means,
Balance qty after lot size calculation, should be round off to the next lot size if it is greater than 50% of lot size.
Similarly Qtyshould be round off to the previous lot size if it is less than 50% of lot size.
Pls help
Regards,
SamieR

Dear Samie,
Case1: As explained by our other forum member you use a fixed lot size and mention the lot size quantity as 10 and the system
will create 6 different planned orders.
Now for case2: the only possible solution will be create a copy of fixed lot size and include the check box for last lot exact in
OMI4 for this particular lot size,so that the system create 5 planned orders for 10 quantity each by mentioning the fixed lot size
quantity as 10 and the last planned order alone will be for 4 quantity.
Check and revert back.

Lot size in MTO

Hi Experts,
I am using strategy 20, my FG batch size is 100 and i have a sale order of 120. I want the system to create 2 planned orders of 100 and 20. I tried with lot size EX and maximum lot size 20, but system made a single planned order of 120. Have i made any mistake, how can i address my requirement ? Please advise.
Best regards
Sm.

Dear ,
In MTO process , sales order qty can't not be spillited beacause , MRP system will not generate planned order detail scheduling to match the Schedule Delivery Date in Sales Order line item .
If you maintain lot size as EX and max lot size is 100 for the quantity of 120,system will create total 2 planned orders.Out of 2 numbers 1 will be with qty 100 and second one will be 20.In OMI4 open the details screen of the lot size which u are using
in the details screen there is a indicator LAST LOT EXACT now if u tick this indicator then the system will create the last lot exact
Basically , your requirement can be done through MTS which will possible .
Hope it is clear

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

MRP Lot Size Difference

Hi All
In OMI4 ie. MRP lot size procedure i see several MRP lot sizes i.e. EX, WB etc....
But only major difference i find is in terms of scheduling i.e.
Blank (Requirement date = delivery date), 1 (period start = delivery date), & so on i.e. 2, 3, 4
Can anyone tell how it works?????? What is its significance
Example would be very good for me
Please suggest
Rgds

Hi Vicky,
Requirement date = delivery date
Planning or procurement proposal will create on req date
Period start = Delivery date
Planning or procurement proposal will create on period start.
ie, if you use period lot size WB,MB.
WB means weekly lot size ie, on Monday cumulated requirement will create for that week. Same for MB, month end planning proposal will create.
Period End = Delivery date
ie, if you use period lot size WB,MB.
On Saturday cumulated requirement will create for that week if you use WB. Same for MB.
This concept will not work if you use planning time fence.

Function of lot size PB,FS.

Hello SAP Gurus,
   Can you help in understanding the function of lot size PB(period lot size=posting period) and FS (Fixing and Splitting).
     I mean i what to know how these lot sizes works.With this also share that where can i get study material on it.
                        Thanking You.

Hi,
Lot Size FS :-
When entering the lot size "FS" and in field the qty as fixed the system is splitting up the planned order qty.
For ex qty is 100 the fixed lot size is 25 the sys creates 5 planned orders of 25 each. The total qty now comes to 25
Lot Size PB :-
In period lot-sizing procedures, the system groups several requirements within a time interval together to form a lot
In PB periods of flexible length equal to posting periods.
Determines how the lot size is calculated for a certain lot-sizing procedure during material requirements planning.
Please go SAP help for details and system configuration in OMI4.

MRP1 Lot Size customizing bundle fullfillment of demands

Hi SAP PP/MM Gurus,
does anybody know a smart way to built up MRP planning parameter, which split the raw material demands into 2 Purchase Requsitions, or Schedule Lines per week. Plant receiving date, 2 fixed days each week (Monday and Thursday only for receiving goods)
Currently we plan with PD and Lot Size WB weekly (99%), some with TB daily or EX.
With WB we plan Schedules with a GR date each Friday to cover the production demands for the complete next week.
Now I want to change and bundle demands and give out Schedule Releases with a goods receipt day on Monday (bundle demands from Tuesday, Wednesday and Thursday) and Thursday. (bundle demands from Friday/opt. Saturday and Monday)
Other settings also thinkable, as I must deal with GR Time and different transport times as well.
I already tested some settings in OMI4, but unfortunatelly not sucessful.
Is the Lot Size the best field to do it?
Can anybody enlight me in that topic?
Thanks in Advance

Dear Alba,
1) after making setting Lot Size: SOP as Lot-for-lot order quantity. save this setting
2) Run MRP in MD02with processing as NETCH
4) make Planning mode parameter as 3 ( Delete & Re-create planning data )
Then check the result

Minimum Lot Size Ignored

Hello All,
To replicate scenario, I have created new material with minimum lot size 10 pcs and created independent requirement (LSF) and then created scheduling agreement.
Independent requirements as 8 pc for every day.
Now when I run the MRP and check in MD04, for the last requirement, planned order was raised for just 9 pcs, ignoring minimum order qty/minimum lot size functionality.
Just for information, Lot size -EX, MRP type PD, Strategy group 10 (though these factor doesnot influence).
Any more settings/customizing required?
BR,
Krishna

Dear Krishna,
I guess you must have activated the check box for Last Lot Exact for the Lot size - EX in T.code OMI4.
If so means remove this and then check with new requirements and MRP run with planning mode - 3.

Monthly lot size problem

hi guys,
i am using monthly lot size"MB" for all my raw/packaging materials.
PROBLEM :
material "M1" has leadtime as 30 days(25 days + 5 days QC)
This material is part of Bill of matwrial of Finished good "FG1"
Now suppose if i put requirement of FG1 for 15th jan 2008 and run MRP today 8th dec 2008.
I should get a purchase requisition with delivery date as 8th jan2008.
but this dosent happen, instead i get PR with delivery date as 2 feb 2008.

Hi,
Think you might have to change the scheduling indicator for your lot sizing procedure in tcode-OMI4.
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.

Deepak.

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.

Question on MRP lot size.

Greetings Gurus
I have a question on running MRP and lot size. We would like to run MRP for our horizon period of 4 months.
Basically, we want SAP to create a single purchase requisition for any requirements that falls within this 4 month period,
But any requirements that fall outside of this, we want SAP to exclude (horizon MRP group set to 4 months)
I am having difficulty making this happen.
I think it may have to do with my lot size definition. Icopied lot size MB and changed the no of periods to 4.
But when I run MRP (@MD03, Processing key = NETPL, Create PR= 1, DelScd = 3, everything else = 1),
it creates 2 requisitions, one for theimmediate 4 month horizon period, but then it creates another requisition for the next 4 month period.
When I set my lot size to MB, it creates everything within the single 4 month horizon period as I expect, but it breaks it up into
requisitions by month.
Any advice on how I can accomplish this?
Thanks in advance
Regards
Ken

Hi Ken,
Txn Code OMI4, make a copy of lot size MB to say Z3 & give a description as required, then change the value of No. of periods to 3 & save. Now you can assign this in your Material Master.
you need copy as Z3 from MB and also assigned to material master (view MRP1), and the short term parameters as per below:
- No of period = 4
- Lot size proced = P
- Lot size ind = M
- Scheduling = 1, else <blank>
For further any issues pls share with us.

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 size use for splitting req. qty. with Two vendors

Hello PP experts,
We have two vendors and we want the each requirement to be split into the two vendor with 30 % for 'A' and 70 % for 'B'.
What are the IMG and master data setting required for the above scenario?
Please let me know whether can will use lot size 'ES' with splitting quota indicator marked in OMI4.
Waiting for your reply.
Regards,
Mona tiwari

Hi Mona,
You have to maiantain first quota arrangement (MEQ1) for the two vendors with alloting the percentage to split the Planned orders/PRs in planning run. Apart from this maintain the lot size either EX, FS or ES with split indicator marked in OMI4 for the quota.
Yes, maintain Quota allowed key in MRP (4) either in purchaing view or in MRP2 view as said by Prasobh.
If helps rewards points.

Report for Reorder point, safety stock, current stock and fixed lot size

Hi,
Purchasing Dept. is looking for a report which can give list of materials falling below the reorder point, so that they can go ahead and create procurement proposals for those materials.
They also want to see the Reorder Point, Safety Stock, current stock and fixed lot size in the same report.
Let me know if there ia any standard report availbale which displays the same or any approach to get the same.
Thanks in Advance.
Regards,
Shankar Goud.

Hi,
There is no standard report because this is meant to be managed by the MRP run.
The MRP lists show all materials that have a problem (such as stock below reorderpoint) but MRP generates requirements for these anyway and so all you need to do is to look for the MRP generated requirements (requisitions?) and you have your list?
Are you using MRP?
If so then please use the standard functions in MRP to get this.
If not, then WHY NOT?

Relation between PO Qty and Minimum Lot size of material master

I have maintained "100" in minimum lot size ( MRP1 View, table MARC and field BSTM) for the material.
I am also succssed to create the Purchase order for 2.5 Qty for the same material. '
I wanted to know, how system is allowig to create the PO with lesser qty or is this view is maintained only for sales?
Please give your expert comments on the same.
Thanks,
Vikas

Used for claculate the procurement qty during MRP and depends on the lot size procedure you select. quota arrangement also uses this lot size.
