Mixed-price variance & Lot size variance

Dears Gurus,
Can anyone give a detail explanation & examples of Mixed-price variance & Lot size variance?
(After reading sap library, I still didn't get clear idea)
Thanks
Ellie

Mixed Price Variance :- This is the variance between a standard price that was calculated in a mixed calculation for more than one procurement alternative and the costing of a procurement alternative.
For Example : Standard Cost was made for a Raw Material A purchased from 2 sources ( X and Y ) with 50/50 ratio..
Actuals it was made of a Raw Material A purchased from X and Y ( in 25:75 ratio ).
The same can happen for production versions also . Standard May have version 1 and 2 (in 50:50 ratio).. actual have version 1 and 2 ( 40: 60) ratio .
Lot Size Variance : Variance due to effect of lot-size-independent costs when the lot size is changed .
For Example : we may have consumables cost per 10000 lot size . Original Lot size during creation of standard is 10000 .
Actually lot size was 150000 .. hence due to change the lot size.. the cost has increased and its lot size variance..
Hope it clarifies..

Invoice blocked for price variance or quantity variance

Dear friends,
In case if in the PO, either there is a price difference between GR and IR or a quantity difference between GR and IR, then does the invoice posted stays automatically in a "blocked" status??
If not, then can we manually do some configuration to make this possible? The intention is that such invoices(with price variance or quantity variance) should remain in blocked status and should not be picked for payment in F110 run.
Please advise asap.
Rgds,
Kunal Vichare.

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.
Regards,
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

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.

Activity variance and production variance seperate in COPA

Dear experts,
My client wanted to break production variance(ko88 in two parts in COPA reports
Total material variance
Total Activity variance
What i am thinking- In PA transfer structure of Production order.I will create four assignements
1)Material price variance-Only RM cost element(Cost element Group)-Price variance category-Material Variance(value field)
2)Material QTY variance-Only RM cost element(Cost element Group)-Qty variance category-Material Variance(value field)
So both assignment linked to material variance value fields.
same way for activity
1)Activity price variance-Only Activity cost element with 43 categoryt(Cost element Group)-Price variance category-Activity Variance(value field)
2)Activity QTY variance-Only Activity cost element with 43 category(Cost element Group)-Qty variance-category-Activity Variance(value field)
So both assignment linked to activity variance value fields.
Is it works for the above requirements or I will face any technical difficulties.
regards
RR

Hi
For sure, it will work....
Another approach can be to update the variance as per cost component structure instead of variance categories in COPA.... Stil the category wise variances can be seen in Other CO reports like Co03 / KKBC_HOE/KKO0 reports

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?

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.

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 ?

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.

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
i cannot upload Docs as my company policy is not allowing
Regards
Madhu

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 ) .
Regards,
Jayavimal

Different fix lot size depending on the production version

Hi all,
I have the next scenario:
2 production versions. 2 different fix lot size por each. So:
Prod Version 1 - Fix lot size 200
Prod Version 2 - Fix lot size 300
I created the Quota Arrangement just to make SAP to take my favourite version. And trought the quota, I can define the lot size for each version. BUT.
If I change the version in the order or in the planned order, the quantity don't change.
So: How can I manage 2 different fix lot size for 2 different product versions? If I change the version once the order is created, how can I do the system change de quantity to the right one?
Thanks in advante
<< Please do not offer points >>
Edited by: Rob Burbank on Oct 1, 2010 2:53 PM

I have n't tried this scenario,
This is my Idea
Create a two production version
for ex: lot size 100 to 1000, set the rounding profile qty as 1000
for lot size 1001 to 99999, set the lot rounding profile value to 5000
BY this way u can get the two lot based on the rounding profie
Expert; please correct if i am wrong

How to perform Data Collection on single SFC with QTY = 1 with material lot size 1?

Dear experts,
We are working with SFC qty>1 on a relaxed routing. At a given operation we want to collect the data on single quantity; i.e. SFC qty on that operation, where the collection will happen, will be 1.The corresponding material lot size is for ex 10. The operator must be able to collect data on SFC with qty=1 multiple times until the quantities will be consumed. He must be also able to collect other values on the remaining quantities on the same operation with the same DC group or other DC groups. How many times the data must be collected is dependent on the shop order build quantity. The data may be collected several time but not more than the build qty. In other words some specific data will be collected on a qty of a product while others will be collected against remaining quantity. The data collection must be also done in a serialized manner.
Here's what we have set up so far:
1) 3 DC groups, each DC group has 3 data fields.
2) Each data field has the following restrictions: Required Data Entries = 0 and Optional Data Entries = 1
3) All DC groups are attached on the same combination of operation\material\routing
4) we are using relaxed routing
Process description:
The operator must be able to collect any data field on single product. For that he will enter the operation where the data collect are attached, he will enter the SFC with qty=1 then he will run the data collection after selecting the appropriate DC Group and entering the needed information. The operator will complete the SFC with qty=1.
The operator will pick the next product, select the same SFC and enter qty 1 and collect other value against this product.
Problem is:
Once the first collection is done on a given SFC with entered qty=1, the system is not allowing the operator to do further collects on the same SFC with qty=1 or any other quantity. He cannot select any DC group from the DC group list. We tried also with the table selection menu on the DC Group list but nothing can be selected.
So we tried to play around with the DC group definitions as follows:
A) we set Required Data Entries = 0 and Optional Data Entries = 10. Still the operator was not able to select any DC group after collecting data the first time. We tried to reopen the pod and list again. But we get the same blocking behavior.
B) we set Required Data Entries = 10 and Optional Data Entries = 1. The operator was able to select the DC group after collecting data the first time. BUT operator must enter the data fields 10 times on one SFC quantity, which is not what we want. Besides again he cannot collect other information on remaining quantities on the same operation.
C) There's an option to serialize the SFC before reaching the operation where the collection is happening, then merging ofter complete. Automation is needed here; hence customization. We are highly avoiding customization now, since we expect the data collect to work well on single quantities even when the main SFC has qty>1
Questions:
1) Are we missing any kind of further configuration\setup?
2) Or the current system design does not allow collecting data on single quantities of an SFC which main quantity is greater than 1?
3) Looking at this link Approaches to Collection of Data - SAP Manufacturing Execution (SAP ME) - SAP Library, there's nothing mentioned about same SFC number with multiple quantities!!!
We are using SAP ME 15.0.3.0.
Thanks in advance for your help

Ali
to collect data for the same SFC multiple times, your system rule "Allow Multiple Data Collection" needs to be set to true for the site.

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.

MRP run on basis of lot size

Dear all
I have two different lot size routing for a inhouse product are 0-2000 and 0-1500 nos . I planned for 5500 nos , after MRP run system should create planned order as per selection of lot size as 0-2000 for 2 planned order and 0-1500 for 1 planned order .is it possible ?
thans in advanced
regards
siva

Dear,
Quota arrangement can be used if the demand (100) is created in which is define the ratio 60:40 but it will create two planned order after MRP Run. Go to transaction MEQ1 maintain a quota arrangement for this material. In MRP 1 view choose lot size with quota splitting and in MRP 2 view maintain quota usage as 4.
