Costing Lot size in CK11N

Hi,
When we do Cost estimates using CK11N or CK40N the lot size arising is not the costing lot size (We gave 1000).
For ex: We gave lot size as 1000, system give 987 or 990 etc.
I have checked if scrap is playing any role in the calculation. But this is coming for materials even without scrap.
Please let me know what might be causing the problem.
Thanks
Naveen

HI,
Is it for all the materials or for some of the materials.
Check the material master, is it maintained wrongly with some value.
Check in the BOM, is there any scrap % is maintained. Check in the material master also the scarp %.
One more thing, Maintain material master with 1000 as lot size and run CK11n for the same material. Let us know the out come.

Default costing lot size and price unit as 100 in material master

Hello,
The costing lot size and price unit is "1" by default in material master. Due to this in CK11N the costing lot size is coming as 1.
Then we go to MM02 and change the master by making costing lot size as 100 and price unit as 100.
Please advise how can we make this default as 100 instead of 1 in material master. So that everytime we don't need to change.
Is it coming from BOM?
Please suggest.

Tapan

Hi Tapan
No doubts, it is ABAP's responsibility to develop it.. It requires ABAP code to be written
The functional specifications need to be given by you.. This BADI is called during Mat Master Creation/Change.. Your Func Specs should cover
1. Which Mat types it should be used for
2. The costing lot size and price unit to be defaulted...
I used it to check Plant = Profit Center and it worked... For whatever checks and validations required during Mat Master creation, this badi needs to be used

Is it possible to change the Costing Lot size for preference calculation?

Hi Gurus,
Is it possible to change the costing lot size for the preference calculation?
Reason for my question is: We have all prices on price unit 100
and we want to use also the price unit 100 for preference calcalation.
But the preference calculation always take price unit 1.
Is there any possibility to set somewhere the costing lot size for pref.calculation?
Thanks

Does really nobody has a hint?

Costing Lot size in Master Material

Hi All,
May i know any settings for default the Costing Lot Size follow by material type?
Example:
Material A - Type is ZFIN - So after i upload material into MM the Costing Lot Size will auto prompt 10,000
Material B - Type is ZPAC - So after i upload material into MM the Costing Lot Size will auto prompt 1,000
Thank You.

Hi,
There is not setting or Config to set Material Type wise Costing Lot size.
System will read the data from MARC-MARC while running the standard cost estimate as per the standard process of SAP-Costing.

Costing lot size error

Hi Experts,
We have repetitive manufacturing here. I just want to know for cost estimate (Product cose collector) which lot size system will take for costing so also if scrap is also there.

Hi Shivkumar
Plz go through the below link hope that it will be useful to you.

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.

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.

Pass on lot size" function not supported in costing runs

hi when i am doing cost estimate through ck40n i am getting following error.
Pass on lot size" function not supported in costing runs
Message no. CK463
Diagnosis
You have selected costing variant PPC1 for the costing run. The Pass on lot size indicator is set in this costing variant. Costing variants in which this indicator is set cannot be used by the costing run.
System Response
The costing run is not created.
Procedure
You have the following options:
Reset the Pass on lot size indicator in costing variant PPC1 so that the lot size is not passed on.
Use a different costing variant in which the Pass on lot size indicator is not set.
if any one had found any same king of error please help me in fix it.
thanks
kareem

Probably this might be the cause
Sales order by Costing
Check out the below
Pass On Lot Size
Definition
If this indicator is selected, the system determines the costing lot size using the lot size of the highest material in the BOM and the input quantities of the components.
Use
1) Do not pass on lot size
If this indicator is not selected, the materials further down in the structure are costed in accordance with the lot size in the costing view of the material master record. When the materials in the next-highest costing level are costed, the costing results of the semifinished materials are converted to the lot size of the finished material to calculate the material costs for the finished product.
2) Pass on lot size only with individual requirement
In the MRP view of the material master record, you can specify that a material is planned as an individual requirement. If such a material is added to another material, costing uses the lot size of the highest material.
3) Always pass on lot size
Here, the costs for all the materials in a multi-level BOM are calculated using the costing lot size of the highest material. This function is used principally in sales order costing.
If you are costing sales orders using product costing for a material with a multilevel BOM that is produced in-house, choose 2) or 3) . For those individual requirements materials, from a business management point of view it is recommended that the order lot size be used when costing the material components going into the finished product. On the other hand, materials subject to collective requirements are generally costed using the costing lot size in the material master record.
Thanks

Costong Lot Size (Variant Costing/Configuration)

We are trying to identify where to establisth multiple costing lot sizes "in general" --- and in relation to use of "Variant Configuration" in regards to Costing Variants for Varient Configurator.

Material Master -Costing 1 screen is where the Costing lot size is defined.
This can be segmented by plant.
Generally (for your standard peice part materials) you want to keep it at "1". There are some documents where SAP uses "10" or "100" this is for some rounding /calculation reasons. But this can cause other issues, and I just find it confusing to be anything other then "1" (although i have only dealt with standard, "tangible" mfg materials)
The only Costing Variant reasons I can think of are for priority of what "cost" to use (i.e. look for last purchased price, then MM standard cost, then previous, etc) I assume you are talking about running a Sales Order Cost estimate on a Configurable Material ?

Lot Size for Split Cost

Hello,
My company has just had SAP installed and I am trying to confirm whether there is a general calculation in SAP or whether it is due to the configuration that has been choosen from our implementor.
I have costed some materials we have setup as a split cost (choice of either purchased or manufactured) and setup the mixing ratio. I then cost it but SAP generates the Lot size automatically and this can not be changed.
i.e. 90%:10% split gives a lot size of 280 (252 and 28) and 50%:50% split gives a lot size of 200 (100 and 100).
Please can you confirm that this is normal and also if it can be overriden?
Thank you for your assistance

Hi,
This is a normal behaviour of the system.

Lot size (materials planning)

Dear All
Pl explain me in details Concept of Lot size and its relavance in Planing of material
Regards
Manoj

Hi,
MRP will firstly determine the EXACT qty required.
It then looks at the Lot size indicator on the material to see what should actually be ordered / produced.
You might indicate an "exact" lot size, in which case it does just that, it tries to procure the exact amount it has determined.
You might want the system to replenish up to maximum stock and so the lot size would cause the exact requirement to be change to the qty to bring the stock up to the maximum qty.
You might want the system to bundle together the requirements over X days, weeks or months etc. and so produce one large requirement instead of one for each.
You can even get the system to determine if it is cheaper to have large stocks and few PO charges or more frequent POs and so cheaper storage costs.
there are lost of lots sizes and they all try to bring in sensible quantities, instead of just what is immediately required.

Sequence dependent lot-size planning as a basis for PP/DS blocks?

Hi ,
I consider the following system setup for a Mill Products planning implementation .
1) In SNP one performs SOP planning with common goals to adjust sales plan, establish equipment maintenance plan, transportation plan, etc. The first month of the SNP plan is supposed to be in daily buckets. Using the SNP optimizer is a good option since the business goal is to use equipment more efficiently, let's say to minimize setup costs, and there are warehouse limitations for semifinished products as well.
2) In PP/DS we are going to use CDP and block planning since it is the best practice.
3) SNP planned orders can be used as a basis for PP/DS blocks on the resource, upon the condition that the configuration of SNP product - kmat variant and block requirements match.
In SNP i see that the SNP PDS has a duration of 1 day (that's fine), but the sequence dependent lot-size planning requires a bucket of at least 1 week long (1 month in my case) since the SNP orders are sequence-optimized only inside of one bucket. The result of such an optimization are additional counters assigned to SNP orders according to their sequence minimizing setup costs. However, orders are not scheduled according to the sequence.
So far it looks like such a combination is not useful as
- Orders in monthly buckets are not scheduled on days and cannot serve as a basis for block dates proposal for PP/DS block planning.
- If a product production volume is less than 1 day, SNP cannot create any more detailed block in principle since the minimal time bucket is daily bucket.
I searched over forums on these or similar topics, however no definitive answer so far for the question in the subj.
Could anyone bring more light on this ? Maybe I am missing something in the setup or sequence dependent lot size planning was designed for other purposes/industries?
Best regards
Vladimir

Hello Asim,
Issue one
in product selection for propagation range you can set your selection criteria which selects the products dynamically. You just have to change your report variants for planning run. Do I misunderstand your concerns?
Issue two
Changing to planning procedure 1 will not delete the PFE but will prevent APO to create a new entry after any MRP-relevant changes happen or heuristic SAP_PP_020 (which creates the initial entry and does the low level code determination) is run.
In some cases procedure 1 will still create a PFE. Please check customizing for details. Thats why I would recommend to create a new planning procedure with "no reactions".
As soon as you prevent APO from creating new PFEs you can just once delete the PFEs in /SAPAPO/NETCH by just setting the first column for these materials blank (select your materials, mark column, delete indicator).
Corresponding table to MDVM is /SAPAPO/PEGKEY. Indicator for PP/DS is NETCH_RRP.
If material is not planned in APO you do not need a PFE in APO.
Issue 3
Maybe utilize table /SAPAP/PEGKEY
As I said if you prevent creating the entry you just have to delete (set indicator blank) once.
Hope that helps.
Regards,
Uli

Lot size YX

hello
Could anybody tell me what does lot size YX "Lot-for-lot with last lot exact" mean?
Thanks a lot.

Hi,
YX is a customized lot size. check if You set the Last lot exact indicator in Customizing for MRP in the IMG activity Check lot-sizing procedure, in order to define lot-for-lot remaining order quantity.
This makes sure last lot is planned exactly same to the net requirement qty at the end of all calculated lots. Rounding does not affect the last lot planned.
Check below SAP help extarct:
Lot-for-Lot Remaining Order Quantity
Use
You can determine in the lot-sizing procedure that the last lot of the planning run is always planned exactly. You thus prevent that the procurement quantities exceed the requirement quantities and, for example, cause remaining stock levels of discontinued materials with high scrap costs.
Integration
This function can be used for all lot-sizing procedures. It is valid for the whole planning horizon.
You cannot use the function in reorder point planning and time-phased planning.
Prerequisites
You have assigned a lot-sizing procedure, for which lot-for-lot remaining order quantity has been defined, to the material in the material master.
You set the Last lot exact indicator in Customizing for MRP in the IMG activity Check lot-sizing procedure, in order to define lot-for-lot remaining order quantity.
Features
The last lot is planned exactly in the net or gross planning segment of the MRP list and the current stock/requirements list. The available quantity at the end of these segments is thus equal to zero.

Combination of Fixed Lot size and Period lot size

Dear all
I have scenario as follows:
1. My supplier's standard packing size of a raw material is 1000 EA.
2. I want to follow period based lot size to optimise my order and inventory cost. But I don't want to use dynamic lot size which will propose dynamic quantity.
So my requirement is like I want to fix lot size as 1000 at material master and Period is Week. My proposal quantity must be 5000 EA for the following demand pattern:
Week 1:1200
Week 2: 1000
Week 3: 1100
Week 4: 1000
System must consider period as well as fixed quantity.
Kindly throw some light on this.
Advance thanks.

Hi
1.As you are looking for Weekly demand demand quanityt , you have to assign Weekly Lot Size : WB.
2. Goto OWD1 and Create a Rounding Profile which will rounds into Weekly Demand quantity for that plant and simulate .
3.Assign this rounding profile in MMR in MRP1
3.DO NOT assing rounding valu as 1000 .Rather keep it blank
Hope this will solve the problem

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
