Parameters controlling: Lot Size

Dear,
I'm a jobstudent at NV Niko and I have to do some research to introduce new features about SAP.
It is about inventory controlling : parameters controlling.
For certain articles, I can access the parameter controlling and for exemple get the bar chart of the Lot size.
The bar takes place at a certain range of coverage at the average receipt and value of the average receipt. Now I have a few questions about this topic:
Are these 2 variables determined by SAP or is it possible to change them and try to optimize?
In the chart, the bar has a specific place, is their a possibility to see what the perfect place would be? By perfect place I mean in which segment should the lot size be in the optimum for a specific article. Maybe their is a function to see this.
How can we do follow-up-analyze-actions? For exemple, when we select more than 1 article, is their a possibility to take out the bad ones (these that are not in their optimum) and that way spot and improve them?
For the safety stock, I have the same problems, so I hope you can help me with these too.
Thank you
Best regards,

Rounding Value,Minimum Lot Size and Maximum Lot Siz parameters

Hello Gurus,
Please explain me the what is the use of the parameter Rounding Value
,Minimum Lot Size and Maximum Lot Size parameters in the product master and how does it in impact during the Heuristic Run?
Thanks.

Rounding value is the incremental quantities in which the order can be produced/procured. Eg. if orders are possible with quantities 40,60, 80, 100 etc..then rounding value is 20.
Min lot size is the minimum quanity in which order can be produced eg. 40 in above example
Max lot size is the maximum quanitity in which the order can be produced/procured. eg. 100 in our example
Impact on Heuristic run: heuristics takes all the above parameter to plan supply order. eg. if requirement is 55, it will supply plan for 60. If requirement is 120, it will produce two orders - one for 100 and the other for 20. if the reuqirement is 10, the order size will be 40.
Hope this helps.

'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.

MPS Lot size rounding

Hi,
We have following scenario:
1) FG X with planning strategy 11, MRP Type: M0, Fix Lot Size: 100 Box
2) PIR entered for FG X for 100 box.
3) MPS Run
4) Plan Order of 100 box created
5) Convert to Production Order and final confirmation of op 10 for 90 box.
6) Production Order appeared as receipt element as 90 box.
6) In next MPS Run, Plan Order of 100 box being triggered for the FG X again to cater for the outstanding requirement of 10 box.
The client do not want the Plan Order of 100 boxed to be generated again. the stock initial GR of 90 box is deem to be able to cater for the market. In generak if the requirement is less then the batch size (fix lot size), no plan order should be created.
Appreciate if you have any idea/solution that can overcome the above requirement, kindly share with us..
Thanks.
WH. ONG.

Hi Wan Haur Ong,
Well i gone through with your thread and i am having an idea for your requirement.
As you said that you want only for particularly the the remaining quantity like 10 boxes should have a production., It means only for 10 boxes:
I would like to suggest you there is a funcationality called rework process for that you have to use funcationality called Trigger point for that particular operation:
Please maintain these steps for that operation OK:
First check in Tcode OPJF for the selection id a Priority is defined for the Task list type S with usage 1 and status 4 and then Proceed as follows:
1. Create a Reference op set in tcode Ca11.
Enter the plant,Description , usage and status for the ref op set Enter lotsize and unit of measure.
Enter the op as 0010 / workcenter/op control key/Description for the op Enter the standard values and save.
2. Create a Standard trigger point in CO31.(Ex Production)
Enter the Trigger Point usage /Group as FERT.
3. Tick the Trigger Point Functions.
4. Enable the indicator create order with Reference.
5. Enter the system status as PCNF.
6. Enter change as +.
7. Enable the indicator once.
8 . Now place the cursor on the create order with reference.
9. Goto Parameters.
10. In the Parameter enter in the group the created Reference op set group no.
11. Order type as PP01 and group counter as 1 and save the Trigger Point.
12. Now goto the Routing for your Material.
13. Choose the last op to assign the Trigger point.
14. Select the OP -
> Goto ---> Trigger Point overview.
15. Enter the Trigger Point usage as FERT.
16. Now choose that line ,select the Details---> Trigger Point f7. The system will says standard trigger point exists from which you can select the created Trigger Point (EXx Production)and save.
18. MD02/MD04.
19. Convert the Planned Order into Production Order and Release the order.
20. Now confirm th ops.
21. For the last op enter the yield and rework qty and set the status as PCNF.
22. If the status of last op is PCNF then in the system a POP UP will appear as Activited by Trigger Point /Create order with reference/order number/sequence and op number which trigger point works and enter.
I hope it will helps you, please get back to me if you have any questions OK pop me again.

Madhu.G

Reg: lot size and replenishment lead time

1. please explain about lot size and replenishment lead time.
2. please also explain about consumption based planing and in steps explain how to perform manual and automatic reorder point(transc code please)

You use the lot-sizing procedure to determine how the system is to calculate the reorder quantity in the planning run.
A lot size defining the lot-sizing procedure is assigned to every material master record applicable to materials planning.
The lot size is defined in Customizing by the combination of the lot-sizing procedure and the lot-sizing indicator.
Three procedures for lot sizing are available:
o static lot-sizing procedures
o period lot-sizing procedures
o optimizing lot-sizing procedures
You use the lot-size indicator to define the procedure.
The following parameters are also available for controlling the lot-sizing procedure:
o Short-term and long-term lot size
   You can split the lot-sizing procedure into a short-term and a long-term period. This means that you can select one lot-sizing procedure in the near future and a different one in the distant future.
You define the periods in the section of the screen entitled "End of the short-term period/start of the long-term period".
   The valid from date of the long-term lot size area is defined via:
   - a periodicity
   - a number of periods
   The beginning of the long-term period is calculated by taking today's date and adding the number of periods in the future; the long-term planning period then starts on the next complete period.
   Note
For materials that are planned using the short and long-term lot size,
   it is recommended that you define a maximum MRP period. Defining the
   MRP period has the effect that materials after a certain period are
   included in planning even if no changes relevant to the planning run
   have occurred. This avoids a situation where order proposals created
   with the long-term lot size move into the short-term period because no
   changes relevant to MRP have occurred for the material.
   You define the maximum MRP period in the step, "Define maximum MRP
   period". A material that is planned on a regular basis should also be
   provided with an MRP type that contains the indicator for regular MRP.
o Scheduling indicator
   For period lot sizes, you can use the indicator for scheduling to
   determine whether the availability date;
o is to be set to the first requirements date in the period
o or is to be set to the beginning of the period
o is to be set to the end of the period
o or whether the period start represents the beginning of the planned
   order and the period end represents the availability date (repetitive
manufacturing)
Interpretation of the delivery times
For the lot-sizing procedure, you can also define whether the period
start is to be interpreted as the delivery date or as the availability
date using the indicator, "interpretation of the calendar times".
NOTE
The indicators, Scheduling and Interpr.deliv.times are mutually
exclusive.
Indicator for the splitting quota
For the quota arrangements, you can determine whether the requirements
quantities are to be distributed to several items, that is, whether
they are to be split. With the splitting quota arrangement,
requirement quantities are not simply allocated to the smallest quota
rating. Instead, they are distributed among various sources using the
following formula:
Quantity for source of supply X = Quota of source X * reqmts quantity
Sum of all quotas
Overlapping indicator
The overlapping indicator along with the cycle time in the material
master record are used to split the planned orders into several
partial quantities whereby the in-house production time overlaps by
the cycle time.
Lot-sizing procedure for make-to-order production
In make-to-order production, you can use the indicator, Lot size for
make-to-order production to determine whether,
the order quantity is to be calculated using the exact lot size
the order quantity is to be calculated using the exact lot size and
the system is also to take the rounding quantity or the minimum and
maximum lot size into account
the order quantity is to be calculated using the lot-sizing procedure
defined for the short-term area
Maximum stock level variant
The system only displays the Maximum stock level variant field in the
lot-sizing procedure, Replenishing to maximum stock level. The
indicator only has an effect in connection with reorder point planning
taking external requirements into account and in connection with
material requirements planning and controls how the system calculates
lot sizes.

MRP Type P1 & Lot size PK

Dear All,
This is REM scenario,
Client is going scheduling agreements
material master Settings
MRP Type - P1
Planning time fence - 10
Lot Size - PK
Procurement type - F
GR Processing time - 2 days, No plad delevery time maintained.
in planning calendar we are going with only one day as Friday
and we made previous day is working day if friday is holiday.
After MRP system is proposing dates for schedule lines as
16/06/2010 ( wednesday ) Rescheduling date as 07/06/2010 ( Monday ) ( Rescheduling in i.e 10 )
How system is proposing this dates
Please share your views or if required more info then revert back

Hi ,
Bring process forward (reschedule in)
Within this rescheduling horizon, the net requirements calculation checks whether, after a requirement, a firmed receipt exists, which can be used to cover this requirement. Then the system displays a rescheduling date as well as the exception message Bring process forward for this receipt. The net requirements calculation then uses this receipt and the system will only create another procurement proposal if the receipt quantity is not sufficient to cover the complete requirement. Several firmed receipts can be used to cover one requirement.
It does not take in to account the GR processing time and it is purely based on the stock requirement date , parameters in Procurement and Scheduling in the Material Master
So it will consume the requirement backward scheduling and bring the Process forward.
Kumar which strategy are you using ? scheduling agreement is of weekly , daily or monthly bucket ?
How many days SA bring to Production and How many days SA for forecast you are doing ?
Are you using any Program to convert these SA in to PIR and upload ( using any program ) .

Material Cost Estimate with different lot size.

What happens if the material cost estimate is run twice using different lot sizes each time (all other parameters unchanged) for the same period?
Will the cost estimate run later overwrites the results from cost estimate run earlier (though the lot size is different)? What is the role of lot size in a material cost estimate?

The costing lot size impacts your cost estimate if you have lot size independent costs (i.e. setup cost). Those fixed costs are spread over the costing lot sizee to give you a cost per unit.. Larger costing lot sizes can also help you minimize rounding issues.
You can only have one marked cost estimate in a given period. However, you can create and save a cost estimate as many times as you want as long as you have not marked it for release. When you save the estimate it will overwrite an existing estimate. You also have the option of creating multiple estimates under different versions or with different costing variants.

Lot size not being generated

The scenario is as follows:
We have raw material for our internal consumption. for some reason, we have parted with some of the raw material one of the customer/competitor. since we have batch management in our company, we did maintain so. the objective of maintaining batch is to ease the tracing / tracking of the material.
1.material(raw matl - matl type ROH) created. posted goods receipt with movement type 561. batch no. generated.
2 subsequently, sales order created, delivered, billed. accounting doc generated.
3 Further, returns sales doc generated, delivered and posted goods receipt and returned material directly taken into Quality Inspection.
4 Inspection plan generated with inspection characteristics. control key used is "QM01"
Now, system should generate the lot size for the material returned by the customer, which is not happened so far.
Can someone guide as to how to generate the Inspection Lot?

Hi
Try with this but I am not sure.
In Material Master, select "Quality Management" tab and include Inspection Type 05 and select "Active".
By doing this, as and when PGR (Post Goods Receipt) is done, the respective stock will go to quality automatically.
Thanks

Manual Lot Size issue in SNP

Hi Gurus,
I have an issue while creating planned orders manually in the planning book as it is not splitting into the lot size which was maintained in the product master.
Some details on the issue:
I have a product X and I maintained '4000' as the fixed lot size in product master. When I enter 20000 it should spilt it into 5 batches and which is not happenning and it is placing the entire thing as one bulk order of '20000'.
(If I run heuristics, it is splitting basing on the lot size maintained).
It was working correctly for 1 product and for many of the products it is not working. All the parameters for the products are same and there is no difference.
For the product which was working correctly for one user and for the same product if I try it is not working.
I probed more into the issue to see if any parameters were added in his profile, there is one custom parameter which is assigned which splits the planned orders basing on the lot size maintained. I even assigned that profile, it worked once and later it is not working.
The strange thing is for one user it works and for other users it doesn't even work for the same product.
Note: We recently moved from SCM 4.0 to SCM 5.1.
Did any one faced such kind of issues before? Any suggestions are highly appreciated.
Thanks and regards,
Murali.

Hi Murali,
I am surprised to read the issue. I will never expect manual planned order to get split. The lot size settings are applicable only for automated planning i.e. heuristic (MRP in R/3)
If you have indeed observed that the system splits the orders by lot size, I have nothing to comment. (probably that is why you did not get a reply for almost a day.
If you have found some settings and find that they do not work, please raise a message to SAP for the same.
I do not think system should split the manual planned order.

MRP Settings - Minimum Lot size / Saftey stock /Lot Size

Hi
I am confused about some of the settings , We set M1(Monthly lot size ) and PD MRP type settings, We maintained the Minimum lot size as 2500 lb and the safety stock as 300.
I tested by changing the Parameters , I am confused.
Please clarify me
Did MRP is going to suggest the PR once if the stock went below 300 ?
Did MRP is going to wait for the PIR to get accumulate the Minimum lot size settings ?
What will happend if the time bound is beyond a month ?
Please help me to understand the concept
Thanks
JJ

Hi,
Use tcode OWD1 to create rounding profile.
Select create icon for creating new rounding profile.
Input new profile name.
In that Threshold value & Rounding value is available.
Input your value & save.
In MRP1 view give the input of rounding profile.
Example given below for easy understanding.
Threshold value Rounding value
    1- 20 -
>                20
60- 100 -
>              100
900-1000 -
>           1000
8000-10000 -
>     10000
If your requirement is 7, it will convert to 20.
If your requirement is 23, it will convert to 40.
If your requirement is 76, it will convert to 100.
If your requirement is 435, it will convert to 440.
If your requirement is 844, it will convert to 860.
If your requirement is 910, it will convert to 1000.
If your requirement is 8045, it will convert to 10000.
Hope it will helps you.

CK727 -Lot size cannot be passed on in combination with mixed costing

I get below error.
We have KMAT materials and scenario is Non Valuated Sales Order Stock.
in our PPC4 - we have below settings. (Both are SAP recommended)
Qty Structure tab we have Pass on Lot size "1" with individual requirements (must of Non Valuated Sales) and
Transfer Control "PC03" has "Current Std Cost" with "Transfer only with Collective requirements"
I just created a mixed cost qty structure. In it I even added Costing type "01". Sales order costing type is "18".
Mixed costing works as expected. However we are unable to create any Sales Orders.
Lot size cannot be passed on in combination with mixed costing
Message no. CK727
Diagnosis
For costing variant PPC4 and costing version 01, it was defined in Customizing that a mixed cost estimate should be created for quantity structure category M0001. At the same time, it was defined in the costing variant that the Pass_on_lot_size function should be active.
System Response
Mixed costing cannot be carried out simultaneously with Pass on lot size . Costing cannot be proceeded with.
Any help is appreciated.

Hi Kala,
system's response is correct
In the standard program the combination of mixed costing and
simultaneously pass on lot size is not possible.
Please review SAP Notes 402440, 584420 and 749128 .
In particular the SAP Note 402440 describes the determination of the
costing lot size at a mixed costing in detail.

MD03 generated purchase requisition on 04.11.2011 for 72 pcs.
As you can see the available quantity of material on 04.04.11 will be 84,701 - 8,445 = 76,256. That is more than Minimum stock( 73,476)
Can you suggest why system creates purchase requisitions on 04.11.2011 but not on 05.11.2011
I can only assume that it's a one more feature of MRP. It calculates dates and quantitys to be procured as lot size EX was set in material master record and doesn't take into account increasing of stock due to FX lot size.
P.S. When I clear coverage profile in material master , SAP generates pur.requisitions correctly.

OK, now it is more clear.
First you should know that only target is doing a real impact. Min and Max are just for display.
Since you have period as month, looking at it on daily resolution is not relevant, you should look at months. You can also see on your daily display that target stock level will only change at month turn.
Hope that it makes it now easier for you to understand the system's calculation.

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.

SNP Discrete Opt .... Lot Size is not correct

Dear Experts ,
I need some help with SNP Optimization execution ...... Actually i am executing discrete optimization , using weekly buckets.
For i.e
I have a demand with 100 pc ..... minimum lot size is 60 and max lot size is 62 .....
SNP should create two lots with 60 pc each one , but it is creating one lot with 60 and a second lot with 40 ..... It is considering last lot exact to fulfill demand .....
All PDS have discretization flag and the relevant parameters for discretization are set on OPT profile .....
I some setting missing ?
Please i need some help asap .....
Kind Regards
Mauricio

Dear Nandhu ,
Thanks for you help.
At OPT Profile , Discret Constraints tab at Minimun PDS Lot Size and Integral PDS i am maintaining 90 D ..... and when i execute the optmizer i am using 60 days . The Planning Book Horizons is 3 months in weekly buckets.

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
